You would be surprised

It fucking beats me why this peice of junk still costs so much

Texas Instruments had exactly that same second thought as you! Behold -- the TI-84+c SE!

High(er)-resolution color screen, recharges via USB, and is a bit thinner.

Unfortunately, they didn't have your first thought -- it has the same hardware inside. It takes longer to draw graphs because it has to plot them in higher resolution. Costs the same, too -- over $100 for a calculator with 1980's technology inside.

I remember a story from roman time (or at least really long ago, I'm not a history person) where a boat was built with half the workers using 11 inch/foot measurements and the other half using 12 inch/foot measurements. Needless to stay the boat didn't make it out of harbor. Then there's this.

Hey that's the Casio FX-991ES plus isn't it?

Do you guys really still use TI-84s? The TI nspire is way better and cost like $20 more tops.

I am a sophomore cs student going into my 4th semester. Here's my experience with the calculator policies for tests in different classes:

I always use a TI-84 cause that's just what I own, but I really only use it for the screen size. Any calculations can be done on a 4-function or scientific calculator like you have. When I don't have a calculator with me, I'm able to use my phone calculator app or try to always keep wolfram alpha or symbolab open in a tab on my computer which is helpful for explaining stuff and a larger range of calculations. In other words, you should be fine with the scientific calculator for 1035 that you have, but a more expensive one will make calculations easier, faster, and possibly more accurate (in my experience the keys on the scientific calculators don't register sometimes and are less sensitive than the nicer calculators, which can mess up a calculation - pain in the ass when you don't realize a button didn't register at the beginning of a multi step calculation until after the fact). There are a lot of ti-83's and ti-84's on eBay that are pretty cheap. I just looked and the first couple results were all under/around $40. Hope this helps!

Just recently bought the new nspire cas. Still getting used to it but man is it sweet. Much more modern and easier to use than my 89 that went missing one day

I raise you for best calculator

I like the TI-Nspire CX better. It's a damn nice calculator.

Go with the brand you're most used to. Since it sounds like you use a casio, you'll want this guy.

and it costs about as much as a regular graphing calculator

Same here I'm staring my 3rd year in ME. I've got a TI NSPIRE CX CAS (my school allows it during exams). It does 2D and 3D graphs, it s rechargeable, in color, programmable and does pretty much everything. There s a nice solve function to automaticaly solve equations (even with multiple variables). It also comes with a desktop sofware.

$134.62 on Amazon!! The TI-84 Silver Edition is $119 on Amazon, so that's not that big of a jump

No I don't think so. You will want a scientific calculator that preferably has complex numbers and calculus functions integrated into it. Something like this is ideal. https://www.amazon.com/Casio-fx-115ES-Engineering-Scientific-Calculator/dp/B007W7SGLO?ref_=fsclp_pl_dp_3

Sorted by Price

Same calc that I have but I paid around $12 at Walmart. Does everything you need to do that doesn't require complex graphing or data analysis (at that point you should be using Matlab anyway).

I got the TI Nspire CX CAS for my last couple years of my BSME and I cannot recommend it more! It does everything! Basically a step above the TI-89 but thinner and faster with a color screen and a rechargeable battery.

Oh, right. So what's with HAVING to have a certain calculator? Surely you have one maths class, and can use any one you want, seeing as any calculator will give you the right answer? What I have is http://www.amazon.co.uk/Casio-FX-85GTPLUS-S-UH-FX-85GTPLUS-Scientific-Calculator/dp/B00364NNU6/ref=sr_1_1?ie=UTF8&amp;qid=1394058512&amp;sr=8-1&amp;keywords=Casio+calculator which seems nothing compared to some super expensive TI one.

A graphing calculator definitely helps a lot for the SAT Math Level 2 test, I would highly recommend getting one.

The TI-84 is not worth it though. Most of the people who recommend it do not know about Casio or HP and simply suggest it because they're only familiar with TI calculators. That's why TI is only popular in the US.

The Casio fx-9860GII is half the price of the TI-84, and has all the programs/functions required for SAT and SAT Math II preloaded (unlike the TI-84) along with a faster processor, better display and more space for programs (even though you won't need to program anything).

For less than the cost of a TI-84, you can even buy the fx-CG50 with a color display and 3D graphing capabilities, which just shows how overpriced the TI-84 is.

Even a used TI-84 is overpriced, because the fx-9860GII usually sells for the same price NEW.

If you want even more value, there is the fx-9750GII which is basically a fx-9860GII without a backlight (if you flash the 9860 firmware on the 9750).

It's still ~$20-$45 cheaper than buying a USED TI-84.

The Casio calculators are approved for use in SAT 1, SAT 2, AP, ACT, IB and A-Level exams internationally, so you will not have any problems regarding approval, at least in high school standardized tests.

Now, there are touchscreen calculators and/or a CAS (Casio ClassPad, HP Prime, TI-89, etc.) which are still cheaper than a TI Nspire (or even a new TI 84) but they are not allowed in the ACT, and may or may not come in handy while in college (depending on major, course and professors) so I would just go for the fx-9860GII or the fx-CG50 to be safe.

We do numerical integration without a calculator, it's not that hard. In math classes you have to show how you did that anyway and in engineering classes the integrals are usually easy to do or you don't have to calculate them during tests and exams because everybody knows hot to do them with a computer.

edit: And you could also use a Casio which has these functionalities: FX991ES PLUS. Still a lot cheaper than TI.

Texas Instruments TI-Nspire CX Graphing Calculator https://www.amazon.com/dp/B004NBZAW0/ref=cm_sw_r_cp_apa_i_2lDUCbSD0JK10

If you want an absolute beast of a calculator, I recommend the TI-nspire CX Cas.

It can do anything and everything. It has gotten me through many classes. It can do Complex/Imaginary matrix operations, can graph 3D functions, can solve ODE's, and you can program it to accomplish various tasks.

here

Get this one and you will not regret it. Best calculator ever and is FE approved

I used it for my FE and could really fly on that thing

As a working engineer, I disagree. In my opinion the TI-36X Pro is slightly harder to use and less suited for engineering that the fx-991EX (which

alsoallows you to easily grab and use previous expressions and answers). Not that the TI is in any way bad, but I think the Casio is somewhat better.$17.28 for the Casio

https://www.amazon.com/dp/B00ZZ93346/

18.57 for the TI

https://www.amazon.com/dp/B004NBZB2Y/

Another good choice:

Sharp EL-W516TBSL at $20.49

https://www.amazon.com/dp/B06XS6V17P

None of these are bad choices, but I think the Casio is the best.

It's the one that is recommended by most/all exam boards for those studying further maths gcse. If you aren't doing further maths gcse, the only benefit that a fancy calculator would have is that it is able to solve simultaneous equations for you (however this would only gain you one mark as you need to show all your working out).

Not doing further maths gcse? this is all you need - https://www.amazon.co.uk/Casio-FX-83GTPLUS-S-UH-FX-83GTPLUS-Scientific-Calculator/dp/B001O3IF9U/ref=sr_1_1?s=officeproduct&amp;ie=UTF8&amp;qid=1502886982&amp;sr=1-1&amp;keywords=casio+scientific+calculator

I got the new N-Spire CX CAS . It's dope. Color screen, indefinite integrals, rechargeable battery. Also unlimited nerd cred. I've used it to solve annoying integrals saving me tons of time on tests. (Mech E)

http://www.amazon.com/Texas-Instruments-Calculator-N3CAS-2L1/dp/B004NBZAYS

Especially now when last year's TI-Nspire CAS is $57 on Amazon. Fifty-seven dollars! http://www.amazon.com/gp/offer-listing/B000QSX9EK/ref=sr_1_1_olp?ie=UTF8&amp;qid=1323459570&amp;sr=8-1&amp;condition=new

Disregarding not being able to use it on certain exams I haven't seen a calculator better than my TI-nspire CAS. As far as I know it can do just about anything and personally I find it much easier to type things in and do it quickly. the screen is also fairly big

I got the non color version from Amazon new for $60 like 5 years ago

Ditch your calculator Smart...

What I would suggest you do is make an excel file with all the topics you need to cover and give a deadline for each one (like this http://i.imgur.com/OWj8D8D.png) Try meeting the deadline obviously. Revision guides are worthless, dont buy any. You wont need them. What I would recommend is using Edexcel and your exam board as they have something called "solution bank" which comes on a CD supplied with the book which shows the worked solutions for every question. Use examsolutions as well when doing past papers and thats all you need. I only recommend buying this calculator as it allows for numerical integration and differentiation which makes it easy to double check your answers.

Actually, It's probably the TI-Nspire now.

Casio FX 115ES Plus. I've been using it for a while its saves me a lot of time when doing multiple cross products and solving simultaneous equations (because you know, aintnobodygottimefothat!). It also has more features that you would find helpful. Another contender is the TI-36X Pro (recommended here quite often although I've never used it).

For a calculator, I'd recommend a scientific calculator+wolfram (I like thisone). For notes, I tend to keep one notebook for each course+loose leaf for homework.

FYI I wasn't calling your position naive, you actually identified some significant factors. I was just building on your argument. If perfect competition existed, competitors would naturally emerge. Thus there are factors that prevent significant competition from emerging.

The fact that that TI-83 is the recommended calculator in some classrooms—and they

arerequired in others—means that the instruction is geared towards use of the TI-83. Sometimes, even the textbooks give instructions on how to solve problems with a TI-83 specifically. From a student's perspective, the mathematics course gets much more difficult without instructions on how to solve the problem with their most useful tool. From a teacher's perspective, it is much easier to teach a classroom with a single brand of calculator than it is to teach a classroom where every kid has his or her own. The same economies of scale apply to the county level.The other calculators in the TI-83 price range of $100 from competitors are much more sophisticated, including a color graphing calculator from Casio and a calculator with the capability for 3D graphing from HP. Meanwhile, calculators with similar competency cost about half what the TI-83 costs. I would say that is significant undercutting.

TI gained a monopoly because of economies of scale in education from having a standard calculator. There's nothing necessarily malicious about that. But it is pretty clear that they are exploiting that position to serve their own self-interest, as businesses are wont to do.

An Alpha Smart Neo 2 with a nightlight might be an option. Just plug it into a computer later and it'll transfer all the text over. Useful in lots of other situations where you want to write without the distractions offered by modern devices too.

What you are looking for is an "AR-7778 musical calculator" (amazon link)

let me introduce you to the best calculator i've ever used,

http://www.amazon.ca/Casio-FX-115ES-Plus-Scientific-Calculator/dp/B007W7SGLO/ref=sr_1_1?ie=UTF8&amp;qid=1457070600&amp;sr=8-1&amp;keywords=casio+115es+plus

it can do complex arithmetic, definite integrals, matrix calculations.

anything you realistically need to do, this calculator does it for me.

Hello everyone!

I had been wanting to post my edc for school and felt since the semester is almost over, now would be a great time. I am a computer science major and have been carrying this with me for several months now. Also, pls excuse the obvious line down the middle - i merged two seperate pictures together. So here is my edc from L>R, T>B.

I do carry all of this with me. It's not too heavy as I've tried to minimize the weight of the items I did decide I wanted to carry.

Some bonus pics are below:

[The reason I carry the extra monitor/keyboard/mouse/etc] (https://imgur.com/n6QRldz)

This is the one I use: Casio fx-115ES PLUS

$13 and does 99% of what I need it to do. Anything it can't do I just plug into Wolfram Alpha.

If you're looking for a writing gadget that's still portable but a bit bigger, I just wanted to mention the Alphasmart Neo 2. It's basically a full-sized keyboard with a built-in word processor that stores a couple hundred pages of text and that's it. Coincidentally powered by Palm OS. It connects to your PC as a USB keyboard, and when you hit the "send" button, it types out the contents of its text buffer into the word processor of your choice on your PC. I picked one up for $40 on Amazon:

https://www.amazon.com/Neo2-Alphasmart-Processor-Keyboard-Calculator/dp/B00T0ZG06O

TIL.

Okay I just checked the prices and I realize it's not that expensive. It's just above a $100 on Amazon which is a pretty good deal (considering you buy refurbished and not new.)

I used two calculators in my algebra, trig, calculus, and stats classes:

(1) TI-89. I just got the most basic model I could find on craigslist. It cost me $50. I'll probably be able to sell it for $50 if I ever want to get rid of it. It's handy to keep around just in case. It is useful for calculus because it is the cheapest TI calculator that can solve derivatives, integrals, differential equations (etc) symbolically.

(2) Casio fx-115ES. This is a scientific calculator, and I find myself using it whenever I need a calculator. It has a pretty intuitive interface that can save you from dozens of parenthesis when writing a long expression. Also, it can do definite integrals and evaluate the derivative of an expression at a given x value.

I find that when I want to do graphing or statistics or whatnot, I usually end up using a computer. As such, I haven't touched my TI-89 in a while. I mostly use it to loan out to friends and other students.

Just because it doesn't have graphics and isn't programmable doesn't mean its junk. There seems to an attitude in US schools that you absolutely

needa graphical calculator, when you really don't. A calculator like this is really all you need.Just a normal scientific calculator??

Casio FX-85 GTPLUS is a good calculator.

https://www.amazon.co.uk/dp/B00364NNU6/ref=cm_sw_r_cp_api_iqiKybN458YPN

Even better, a Casio FX-991ESPLUS, it's even silver!

>I believe that the government should require that all publically funded schools accept all graphing calculators regardless of who produces them or what brand they are and instead bases them off of functions necessary to complete the curriculum.

Already you can use any graphing calculator. Incidentally, there are numerous calculator companies in business. Do you mean for the government to impose penalties on schools that recommend a specific graphing calculator to complete the course? What kind of law do you want to make and what would it say?

Aside: there are legitimate reasons to ban graphing calculators that are too good in classrooms. If there is a test on integration, having a calculator that can show you step-by-step symbolic solutions can invalidate that test. You can argue that being able to integrate by hand is a stupid skill that's not worth learning, but that's a very separate argument.

See more SAT rules for calculators here. Both for a stunningly long list of competitive graphing calculators and for some features that are banned in some testing situations.

>So, for starters because of the textbook industry the use of the TI-83/84 has run rampant and has monopolistic competition on college campuses (and thus relevant work places) as a result.

So? It's tried and true. I work in finance, and we all all use Dixon Ticonderoga pencils because they work. Oh, and we all have HP-12cs, lol. Would you propose a law banning Dixon Ticonderoga because their lead is too smooth, and their grip is so light, and their eraser too supple? "Your product is too good! Destroy it and design it again!"

>This monopolistic competition allows them to charge up to $150 for a Calculator that has not been improved upon since 1996.

So? Lots of things aren't cheaper than they used to be.

>Today most phones (even non smartphones) are more powerful than both of these calculators in terms of raw hardware.

I hate responding to every single one of your points with "So?" but really: "So?"

What, specifically, do you want a graphing calculator to do that it can't do? Keep in mind also that there are way better graphing calculators out there, just nobody buys them because the purpose of a graphing calculator is to help students learn math skills more than it is actually used to solve problems.

I can't honestly think of a single function I want on my TI-84 (as a learning/educational tool) that it doesn't have. It would be nice if it were faster, I guess, but it doesn't make sense for them to redesign an entire calculator just to make it as fast as your dumb phone.

It does everything that you want it to do.

With CASIO calculator keys.

If you're looking for advanced I would recommend a ti-89 though most courses may not let you use something with a CAS. You might like this: (https://www.amazon.com/Casio-fx-115ES-Engineering-Scientific-Calculator/dp/B007W7SGLO)[Casio fx115es] or the ti34 multiline

Go for TI- 84 plus. It was and still is the most reliable scientific calculator, I have used that model since high school and its never let me down. Although I've dropped them down a lot hah. The newer versions are even sleek and aesthetic, decent and affordable. Don't go for low quality garbage, they always come with some kind of catch.

https://www.amazon.com/Texas-Instruments-Blueberry-Graphing-Calculator/dp/B00UG8TN2M/

If you are in India, then

https://www.amazon.in/Texas-Instruments-TI-84-Graphing-Calculator/dp/B00TFYYWQA/

&#x200B;

Don't go for Nspire or others, I don't think there is any need for those in bachelors engineering courses.

It's not a great idea to go for used when it comes to Scientific Calcies, as they are a very handy tools and usually people don't sell their calculators unless its not working properly. Its like purchasing a used drill set not always a great idea.

http://www.amazon.com/Prizm-FX-CG10-Color-Graphing-Calculator/dp/B00481K4KS/ref=sr_1_1?ie=UTF8&amp;qid=1323465336&amp;sr=8-1

That's the one I have. The screen is fucking amazing and the calculator doesn't feel like a brick in my hand.

Casio fx-83gt Plus. I bought it on a whim when it was a fiver at Tesco. I'm not sure I like the 'Natural VPAM' thing. I preferred how calculators used to work. Well worth a fiver though.

Most of my professors so far only allow Calculators that are allowed on the FE. as /u/DrJamaican mentioned, get a good calculator that is allowed on the FE and learn how to use that as you would breathe. I usually recommend the Casio FX991EX, it does spreadsheets and 4X4 matrices and the display and overall functionality is amazing compared to it's only real competitor the TI-36x Pro. The only thing the TI does better is keep memory of operations between power cycles. If you are gonna graph any for a class it is gonna be using MATlab or some other software package. So save yourself the money on a graphing calc and buy two great scientific calculators (always need a backup).

I have a Ti-nspire CX, selling for $75 shipped. Best graphing calculator you can get.

Texas Instruments TI-Nspire CX Graphing Calculator https://www.amazon.com/dp/B004NBZAW0/ref=cm_sw_r_other_awd_dBN1wbPD6DVM0

Here the calculator most people get for A-Level Maths/Further Maths is either this one (£68/$88) or this one (£29/$38). A-Levels are the main academic qualifications in the UK for 16-18 year olds in college.

Casio FX-991EX Engineering/Scientific Calculator, Black https://www.amazon.com/dp/B00ZZ93346/ref=cm_sw_r_cp_apa_dBGYBbKC723D3

The newer version

Start thinking only in solutions. Don't dwell on things you believe you can't do, like not being able to read or write. Think about what you can effectively do to write, try things out, different things, different situation, try to find a place where reading/writing for you is managable.

&#x200B;

About writing; I have trouble in getting distracted. I write best when I write on an Alphasmart (https://www.amazon.com/Neo2-Alphasmart-Processor-Keyboard-Calculator/dp/B00T0ZG06O) .(Mobile physical wordprocessor with no internet access) This is best done in an empty room or in public.

It's real! https://www.amazon.com/dp/B07RL7HM5V (as of this posting). And you're dead on, /u/1brkn1 it's miscategorized in the Television & Video department so naturally it's wall-mountable.

here you go

From what I've gathered, TI appears to be releasing the European version publicly earlier. I think that their primary motivation for keeping these under wraps is so that kids can't use them on primarily US AP exams because stringent proctors might flip out if they see a calculator not on the list. European versions also have some minor differences in their abilities, specifically CAS and exact arithmetic, so it would probably be wise to stick to your local domestic version if you're planning to take standardized exams with it such as AP exams and other CollegeBoard exams. That could be a reason why my delivery was scheduled for today instead of the AP AB/BC exams which occurred yesterday.

Amazon (USA) has a listing here that just got posted recently, because I checked a few days ago and it wasn't available. It says that they're shipping next week (May 20th), but it's a third party seller of which claims to have very positive reviews for TI products, but I'm not sure if I would trust for a (semi-) major launch like this. I think that for the vast majority of people who don't need heavy computation, a first-gen color NSpire will do just fine, and if you really need the power, you should honestly be using Desmos/Wolfram|Alpha on desktop. This product is mainly for looks/status from my first impressions, but feel free to correct if I'm wrong.

&#x200B;

Edit: spelling to satisfy the CMB. Also, something of note might be to try searching with double quotes "" because Google treats the text inside only for exact matches, and to use the Roman numeral II because it appears that most sites are adhering to the TI branding of II instead of 2.

I think that’s an fx gt85 Plus. Standard calculator that every school has

I’m a high school math teacher. That isn’t any normal price I’ve ever seen for a ti-84+, it’s actually about $100. Here’s the standard amazon listing which is consistent at most other places. If you want the color version (which I don’t recommend) you’re looking at about $150.

Btw, the color versions are backlit and rechargeable. This means that since they’re backlit they suck down the batteries and have to be recharged way more often than the non-backlit version which last forever on one set of 4 AAAs. Also, those rechargeable batteries only take so many charges before they start seeing decreased life. I’ve had multiple students who have to charge their calculators weekly or more and eventually they won’t hold a charge. You can take apart the calculator and replace them yourself if you don’t mind getting into it. But, lots of people aren’t comfortable with doing that and ti isn’t going to do it for you.

Secondly, this whole calculator conspiracy theory is just that. We math teachers don’t suggest ti because there’s some ti rep padding our pockets or because “Pearson is paid blah blah blah”. We suggest them because they’re simple and idiot proof. The older ones were tanks. They’re more intuitively set up than Casios or HPs. They’re just good calculators.

much better than ti36

I used a super fancy ti calculator (ti voyager, had a qwerty keyboard and everything) for my first two years of college and then my engineering profs banned it and told us we could only use fe (fundamentals of engineering exam) approved calculators. I then went and researched the best of those calculators and discovered the Casio fx 115 es.

http://www.amazon.com/gp/aw/d/B007W7SGLO?pc_redir=1408869410&amp;robot_redir=1

I'm not trying to get you something you don't want but after learning to use this calculator i realised how much of a waste of money graphing calculators are. You are never asked a question on any college level test that says "plot what this function looks like" unless it is something your calculator can't handle and for homework assignments you can just install x cas on your smartphone.

http://www-fourier.ujf-grenoble.fr/~parisse/install_en

There is also a ti equivalent of the calculator so noone here thinks I'm a Casio rep but imo the Casio is way more capable and user friendly (I'm personally fond of the button layout)

http://www.amazon.com/gp/aw/d/B004NBZB2Y/ref=mp_s_a_1_1?qid=1408927322&amp;sr=8-1

anyway what I'm saying is I'll get you either of those calculators (Casio fx 115 or ti 36) but not the graphing calculators because I don't own any and think they're a waste of money for over dependant math newbies. If that interests you let me know and I'll buy one for you asap.

Seriously these calculators can do vector math, dot products, derivatives and integrals, probability (ncr and npr) and list values of functions in a table format (as close to graphing as you need to get imo). Even the normal graphing calculators can't do all that!

It's not a bad idea to do this to make sure you haven't been given one of these.

i have 2 calculators, the first casio 115ES is allowed on the FE exam (Fundamentals of Engineering) that you take upon graduation so its good to be familiar with it

Casio 115ES has a natural display thats unbelieveably good, much better than other 115 series casio.

$14 http://www.amazon.com/gp/product/B000A3IAHM/ref=oh_details_o03_s00_i01

the seconds is a TI N-spire CX CAS (Computer Algebra System)

it allows you to solve any equations symbolically ex: integrating from x to infinity using x and infinity as terms..

it will probably not be allowed on exams but for $144 from amazon it has a color screen and touchpad mouse cursor and is within 2 years old and will be relevant for the forseeable future

Let me introduce you to my buddy, the Alphasmart Neo, they don't make them any more so snap one up while you can. Endless battery life, instant on/off (no boot time), no distractions, no gimmicks except spellcheck, it saves every keystroke and stores up to 8 running files that sync to word.

Not actually a 4 function calculator but just about the same thing. This is what we’re required to use, department wide.

Casio fx-260 SOLAR Scientific Calculator, Black https://www.amazon.com/dp/B000Q5XTBQ/ref=cm_sw_r_cp_api_fCtGAbKWZ3YKV

I miss CAS :/

For general number crunching I use my trusty TI-36x. It's $20, does definite integration and derivation and pretty much everything else that a TI-84 does (minus the graphing). It's also solar powered and rather small.

For heavy duty calculations I use my TI Nspire CAS

>I've been wondering which calculators are easiest to use and do all necessary calculations for engineers.

Casio fx-115 has stood by me for more than a decade. It got me through school and beyond and I've yet to replace it or the batteries.

It also happens to be acceptable for the FE/PE exams (something I didn't know when I bought it).

CE here (4th year). Had an 84 Plus coming in, bought the nspire cas a year ago and extremely happy with it. It's honestly not that much more $ than a new 89 (get CAS because complex number math). Really nice functionality, matrix solvers, statistics stuff. Didn't need it for first year but later math courses it has been quite helpful. My EE buddy is always stealing my calculator for his exams :). If you have questions feel free to ask.

I've got a HP-35s and the Casio FX-991EX amazon

&nbsp;

I bought the Casio as I couldn't take a programmable calculator into exams, and the 991EX is probably the best scientific calculator around right now. It's a newer model than the ES with a better display and a couple of extra features such as spreadsheets. The only negative I have to say about it is you only get 5 columns in the spreadsheet. That's 5 more than most calculators and I've used it successfully for stability calculations in naval architecture exams.

&nbsp;

If you can get something programmable but don't need graphs, get a HP 35 and learn RPL and stack memory; I can punch numbers out in half the time on that than i can on the casio.

Sharp Electronics EL-W535X Writeview. It's approved by the ENCS dept.

It's around $150 on Amazon...

http://www.amazon.co.uk/Casio-FX-83GTPLUS-S-UH-FX-83GTPLUS-Scientific-Calculator/dp/B001O3IF9U/ref=sr_1_2?ie=UTF8&amp;qid=1333233060&amp;sr=8-2

Don't quote me, but I think this can do it.

Got one lying around at my friends house, I'll ask him to check

For my first two years of EE coursework, I'd say 90% of the math can be straight up solved with algebra, or simplified to a first order differential equation.

Engineering is not about calculating hard math, it's about knowing when to apply which techniques.Uh. Best tip I can give you is learn to be fast with your calculator; it'll save you a lot of time. My personal favourite is Sharp EL-W535XBSL. This underrated $20 tier of calculator lets you convert between polar/rectangular coordinates, basic matrices up to 4x4, binary/hex calculations, unit conversions, and all your basic trig functions. And you're not lugging around that $90 TI brick that's banned from exams anyway.

Ohyeah. One of my profs made the circuits to water pipes analogy. Learn those, they're fun and helpful.

Lab coats are provided by the department in 99% of cases in my experience. I wouldn't even be allowed to bring my own one. Safety glasses is not something biologists use the vast majority of times. Really most of the things biologists use on a daily basis are either too expensive or impractical to give as a gift to be honest. I personally love to have a proper calculator in all my labcoats (3x, this one) because there's nothing more annoying than these one-line calculators lying around everywhere. Maybe a nice new briefcase/bag with a good calculator? Hard to get more biology-themed and be useful at the same time I think.

Yup. It's an extremely powerful calculator that very few people know about because everyone would just go buy TI stuff. Honestly felt like cheating sometimes when I took exams with it.

&#x200B;

It looks like the FX-991EX ClassWiz is the newer model though.

https://www.amazon.com/Casio-FX-991EX-Engineering-Scientific-Calculator/dp/B00ZZ93346

I second this. If it is allowed it is THE best calculator to have.

https://www.amazon.com/Texas-Instruments-Nspire-Graphing-Calculator/dp/B004NBZAYS/ref=sr_1_3?ie=UTF8&qid=1539915403&sr=8-3&keywords=nspire+cx+cas

&#x200B;

Though if you plan on taking the state licensing exams it might ruin you as graphing calcs aren't allowed on those tests.

I just checked Amazon. They have TI 84 Plus for $90.00. Proof

got a link to the CX II CAS? All I'm finding is this and it doesn't exactly look comfortably legit

Ah, that's pretty much the same then, we were just told to buy a scientific calculator. If anything influences what brand people get, it's probably what others already have, or what they've seen their older siblings use. I know one guy bought this one after he saw me use mine to automatically solve an equation, that was about the most complex we were allowed to have

I love my Sharp EL-W535 Writeview calculator. It's simple but holds the numbers and "looks" like a textbook without the graphing technology.

You can get it here for around $12 https://www.amazon.com/Sharp-EL-W535XBSL-Engineering-Scientific-Calculator/dp/B004J6M29S

Texas can and they did...

i have an fx155es too, if i was buying a calculator today id get either this or this

I used this one in addition to the Windows calculator. The Windows calc is the easiest way to convert between binary, hex, and dec, though.

Yo te recomendaria esta: Casio CG10

La use los ultimos 3 años del colegio por que me pedían gráfica y realmente te la enseñaban a usar. Lo que fue contraproducente a la hora de rendir matemática en el CBC y me digan che u/ZellahYT que mierda haces con eso, tenes que aprender todo de nuevo y a mano ahora.

What exactly does a graphing calculator do? In the UK, they're not terribly common - I did my degree with the same calculator I had in school plus Excel.

Buenos dias muchachada (No me peguen, ya me voy).

Calculadoras graficadoras para la facultad? Si, no, por que?

&#x200B;

Dado a que mi calculadora cientifica no hace ni siquiera resolvente, estaba viendo de traer con Grabr una Casio FX CG50 pero no se.. ya veo que al final es una de esas pelotudeces que no necesito (Dicho sea el paso, hago ing informatica y en este momento estoy cursando Analisis 1). La otra opcion era traer algo mas sencillo como una Fx-115ES Plus o similar pero ahi ya no se si vale la pena con Grabr.

Edit: Y si tienen recomendaciones de modelos, se las tomo también.

&#x200B;

Saludos!

Boom. I'm a math expert now.

Well I already have the TI-84 I mentioned, which is not CAS capable. If necessary, I can fall back on that.

Just to be certain, you are referring to this bad boy, right?

Thank You for your positive response! As far as tips, I would recommend doing practice test on https://www.khanacademy.org/ and this will help you to increase your SAT Score and the format is exactly like the Official College Board SAT Exam. For the Math section I would recommend the TI-84 Plus CE because of the color display which makes plotting multiple graphs useful, a rechargeable battery is nice as well too. https://www.amazon.com/dp/B00TFYYWQA/ref=cm_sw_r_tw_apa_i_tSU2DbN5ATPRQ

For the Essay section I would recommend following the perfect paragraph format which is:

1 Topic Sentence (TS)

1 Concrete Detail (CD)

2 Commentaries (CM)

1 Concluding Sentence (CS)

As far as I know, the TI 84-Plus CE-T is the best one available for Maths HL, as n-spire calculators are banned. If you’re buying an 84 Plus, buy a new and thin one like this.

i was actually doing some poking around and found a graphing calculator that dosen't suck as hard as the TI shit, and it looks like the price has gone down since the last itme i checked http://www.amazon.com/Prizm-FX-CG10-Color-Graphing-Calculator/dp/B00481K4KS

Would something like this be fine: http://www.amazon.com/Texas-Instruments-NSCAS-PWB-1L1/dp/B000QSX9EK/ref=sr_1_24?ie=UTF8&amp;qid=1343931357&amp;sr=8-24&amp;keywords=ti84

It seems like the best price at the moment.

You won't find calculators like that in England. The only one you'll find is a Casio FX 85GT PLUS

http://www.amazon.com/Texas-Instruments-TI-84-Graphing-Calculator/dp/B00TFYYWQA

They've changed it somewhat.

They do have the TI-84 Plus CE now.

Well actually... the Ti-84 Plus has been updated. And it's really nice imo

Just a bit of advice, start early in your degree getting used to a NCEES approved calculator. HP35s is my favorite and I still use at my job and the Casio is another good choice.

I don't know what major you are but if you are in engineering I would strongly recommend one of these for a little bit more:

What's your budget?

You could buy a used ThinkPad.

An x230 ca go for about £150 on ebay and is an insane bargain. Those things can run win10 just fine, as far back as the x200, which is even cheaper. The keyboards are phenomenal- I had an x230 which unfortunately broke, and now I'm typing on a newer thinkpad.

Or you could get a cheap bluetooth keyboard on amazon- there's a lot of good ones.

If you prefer writing on a pc, you may consider a mini prebuilt pc such as a pi or an intel nuk, and get a keyboard for that.

Perhaps you could use a library computer? Those generally are free to use, and you could save your work on the flash drive.

If your laptop was new/you had a warranty/ it had a barcode of some sort, perhaps you could contact the company it is made by? They may offer you a discount or even a replacement (though that's kinda rare).

Bluetooth keyboard or ThinkPad is my go-to though.

Actually, an even better solution could be a keyboard with a screen. There are some keyboards with small panels attatched that are used specifically for typing documents- they're fairly rudamentary but will work just fine. They can connect via usb most of the time and are very cheap. Try something like this

I hope this helps bro!

Edit: As others have suggested, use a cloud service for backups at least. I use OneDrive as it's built into windows and supports android and iOS, but Google Drive is also reliable and gives you more storage for free.

TI-nspire CX no question

Just a few more dollars than an 84+ Silver Edition on amazon.

It's got a faster processor, more RAM/ROM, color screen, better controls, overall a calculator for this generation. The 84 series is from the early 2000s I believe in this model is a lot more recent.

Plus I just bought one and all the 84 users in my math class are jealous of its beauty.

Used only in Radian mode.

Sooo many versions of the 89 and I dont know what the differences are. There's the 89, 89+, 89 silver, 89+ silver & 89 titanium.

Here's a link to the Nspire, its a relativly new model, has a color screen & touch pad.

There were mandatory for us

https://www.amazon.com/Texas-Instruments-TI-84-Graphing-Calculator/dp/B00TFYYWQA

This 'next gen' Ti-84 got me through my AE degree completely fine and I never found myself needing anything more powerful or capable for the entire curriculum. The build quality is excellent, it's rechargeable, durable, and it's very lightweight. I have no concerns sticking it in an outer pocket in my bag since it's not fragile. Plus not having to worry about batteries is great and this is faster than a standard Ti-84, not to mention the color display.

Overall I think this would make an excellent gift for your son.

edit: it also comes in red which is what I got.

100-140€ range over here (conversion varies)

I'd personally suggest one of these https://www.amazon.com/Texas-Instruments-TI-84-Graphing-Calculator/dp/B00TFYYWQA as they're a pretty solid compromise between cost and function
