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.

Probably.

But a used TI-83 Plus is only about $30...

Amazon Used TI-83+

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.

and it costs about as much as a regular graphing calculator

Check out my new calculator https://www.amazon.com/Texas-Instruments-TI-84-Graphing-Calculator/dp/B00TFYYWQA

I wanted to get the pink one but it was like 40 extra bucks...

A

literalpink tax...For those who are curious it's $127 on amazon.

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

http://www.amazon.com/Texas-Instruments-N3-CLM-1L1/dp/B004NBZAW0/ref=sr_1_1?s=electronics&amp;ie=UTF8&amp;qid=1314261778&amp;sr=1-1

No way, I'm

waymore oppressed. When I tell people I'm a calculatorkin, they're like "wtf is that?".No one understands me. I was a Casio fx-9750gii in a past life! No one understands! Check your privilidge!

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.

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.

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.

Well, maybe I should have mentioned that it was a collective order. Amazon lists it with 150€. 125€ are still an awful lot of money. Additionally you are obliged to buy books and other stuff for the new school year. A tidy little sum...

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

edit: https://www.amazon.com/gp/offer-listing/B000QSX9EK/ref=dp_olp_0?ie=UTF8&amp;condition=all&amp;qid=1486517993&amp;sr=8-4

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

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.

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:

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.)

Texas Instruments Nspire CX-CAS

>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.

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.

&#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.

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

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.

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’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.

I have a CX CAS I was thinking about selling if you want it.

&#x200B;

I'll let it go for $80

They also have some really fancy graphing ones.

Texas Instruments. Balls of steel.

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

You're not going to regret it. But I would do more shopping instead of just running with Reddit's advice. Sure the CX CAS is more than you need most of the time, but did you know it's not the fastest CAS calculator on the market? HP actually makes the fastest one. Also Casio makes a very user friendly touchscreen calculator that even comes with stylus. How cool is that?

But like I said, the CX CAS is basically all you need. I just hate seeing these calculators get left out all the time.

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

http://www.amazon.com/gp/product/B004NBZAYS/ref=oh_details_o03_s00_i00

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

TI36x Pro: http://www.amazon.com/Texas-Instruments-36PRO-TBL-1L1/dp/B004NBZB2Y/ref=sr_1_1?ie=UTF8&amp;qid=1407807454&amp;sr=8-1&amp;keywords=ti36x

Not defending TI here, but this looks a bit nicer than what I had in high school:

https://www.amazon.com/Texas-Instruments-Nspire-Graphing-Calculator/dp/B004NBZAYS

There's actually a slim color version now. It has the same functionality as the old one though.

I’m going off what I have seen, and the ones I have seen are more of a brick.

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.

Nope, most calculators with CAS are banned on tests such as the ACT, SAT, IB and some AP exams. You're in college so you won't have to worry about those exams, but some professors and other exams down the line might not let you use it.

I don't recommend getting the first first model, but if you must get a greyscale Nspire, get the one with a touchpad. or maybe even a TI-89 -- they are used by a lot of engineering students.

&#x200B;

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

>with out adding any improvements

I wouldn't say that's 100% true. While the most popular models (Ti-84 series) haven't changed much, the one I have the Ti-Nspire CX CAS has quite a lot of new an useful features.

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

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.

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.

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

Actually, they've improved quite a bit.

I'm am international student for what it's worth. Tha's how much they retail everywhere here...

Even on amazon.uk it costs 100+£ while being on a discount too. Idk how you guys get them for much cheaper

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:

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.

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.

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

the one you linked looks to be permitted as well, though: https://www3.dpcdsb.org/STFXS/Documents/Use_of_calculators_in_examinations_2017__version_1.pdf

Ti-Nspire CX

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

If you are taking more than 3 of MathHL/physics/chem/econ then it would be a great investment.

I wanted to give everyone an update on what calculator we decided to buy for my son for high school this year. We bought the NumWorks Calculator and are planning on him using it unless his teacher will not let him. As a back up calculator I bought the TI-84 Plus CE at Target on Sunday, since it is on sale this week for $99.99. We are going to take the TI-84 Plus CE back if he is allowed to use the NumWorks calculator, but I wanted to get it at $99.99 instead of having to potentially pay the full $139.99 price. Target offers a 30-day return policy on the calculator, so we will be able to take it back after his first week of school if he doesn't need it.

&#x200B;

I had already bought the TI-Nspire CX at our local Office Max for $103.91 + tax a week or so ago, but we are going to return it. It is a nice calculator and seems easy to use in some ways and more complicated in others. The documents feature seems overly complicated for a calculator, but maybe it is needed in some situations that I am not thinking of at the moment.

&#x200B;

Another thing that seems weird about the TI-Nspire CX is when you divide two numbers. If you put in 3 divided by 8 you would think you would get the answer of 0.375, but instead you get 3/8, which is what you entered in the first place. To get 0.375 for the answer you need to remember to use one of the three methods mentioned in the How to convert between fractions and decimals for TI Nspire CX video. I am guessing there is a reason for 3/8 = 3/8, but it seems odd to me.

&#x200B;

TI-Nspire CX's touchpad for moving the cursor around the screen doesn't seem that great based on the Texas Instruments TI-Nspire Review video I found. The TI-Nspire CX emulator is not bad to navigate on my PC with my mouse, but I am not sure how well the actual calculator will work with the little trackpad in the middle of the directional buttons.

&#x200B;

It is nice that the TI-Nspire CX calculator spells out things with full titles instead of what looks like function names on the TI-84 Plus CE. For example, to calculate an "Integral" you need to hit the following buttons on each calculator:

&#x200B;

TI-84 Plus CE:"MATH" > "9:fnInt("TI-Nspire CX:"menu" > "4 Calculus" > "2 Numerical Integral"NumWorks:"Toolbox" > "Calculations" > "int(f(x),x,a,b) - Integral"&#x200B;

This is just one example, but you can see how the TI-84 uses older naming with not a lot of letters for the titles. The TI-Nspire CX isn't bad once you know which menu to look under, but the NumWorks calculator seems easier to use and they show you both the long name and the formula.

&#x200B;

I really recommend downloading the three emulators for these calculators at the following links and trying them yourself to see how they will work before buying one.

&#x200B;

&#x200B;

Watch some videos on each on YouTube and try to figure out how to solve some problems that you find online to see which is easiest to use. The TI-84 Plus CE and the TI-Nspire CX we needed to follow instructions to get the answers to problems. Once we read the instructions for the problems for the TI calculators it was sometimes funny how easy it was to find the answer on the NumWorks. I had to do a little search for how to do a couple of things on the NumWorks, but everything was straightforward and made sense. I don't know if we are missing something and there will be things that are more complicated on the NumWorks, but currently it seems the easiest to use.

&#x200B;

I'm also not a fan of how the TI-Nspire CX buries the "sin", "cos", "tan", "abs", "square root", etc. functions under the "trig >" and "symbols" (not sure what to call it) buttons. I guess it is easy to use them once you find them, but I like how the TI-84 and NumWorks have those functions and others visible on the calculator either on a button or above a button that you access with the "2ND" or "shift" keys.

&#x200B;

My son, wife, and I went through a few more problems the other day and every time the NumWorks seemed the easiest to use without any or much help from searching on Google. The NumWorks calculator just seems more intuitive to use and things make sense. 3/8 on the NumWorks equals 3/8 = 0.375. The NumWorks even says that 6/16 equals 3/8 = 0.375 without pressing any special buttons. The TI-84 Plus CE says it is equal to 0.375 and the TI-Nspire CX says it is 3/8 unless you go through the steps mentioned in the video above, but then you just get 0.375 without 3/8. The NumWorks gives you both answers right from the start, since the developers must've determined you might need both. Do you see what I mean about the NumWorks being more intuitive?

&#x200B;

I really recommend the NumWorks calculator if you are allowed to use it at your high school. If you don't trust me, then try the online version or download it for your iPhone/iPad or Android device for free and see for yourself. I think you will be surprised at how well it works and how old it makes the TI-84 Plus CE and even the TI-Nspire CX feel. Engadget says "NumWorks graphing calculator is made for students raised on tech" and I would agree with that statement. I also agree with Romain Goyet, the creator and head of Numworks, when he says "If you give students something that's 25 years old, it's going to seem complicated to them." The TI-84 Plus CE seems complicated and like it was made back in the 1990s. The NumWorks graphing calculator seems like something that was made in 2017 and a lot easier to use.

here is a ti nspire cas for $30 plus a little shipping. You can get it for a little less but I don't trust the sellers for those. This is the calculator I used and this is where I bought it.

*cough*

OP has this calculator, not the bottom tier you linked.

> more expensive than three normal 1080p monitors.

if you're buying $99 monitors, then they're probably crap

>>Since you're all being pedantic idiots, I looked up the actual price

You're not getting a good <$93 monitor, and 7ms is only good for console gaming. Try again.
