Best scientific calculators according to redditors

Report it to the police, they will direct you to the correct department. Insider trading is taken very seriously in the UK.

*Presuming your not talking about Casio calculators.

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

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

I've got a calculator for all my chips: http://www.amazon.co.uk/dp/B0034BAQS8/

Be careful.

Ask around your university before you spend real money.

Many university professors forbid the use of calculators during exams. So its best to not become dependent on them.

Wolfram Alpha can help you do homework, but you better know how to do it all long-hand.

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

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&qid=1394058512&sr=8-1&keywords=Casio+calculator which seems nothing compared to some super expensive TI one.

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).

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.

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 also allows 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.

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

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&ie=UTF8&qid=1502886982&sr=1-1&keywords=casio+scientific+calculator

If you really need to write the fractions, my personal pick would be the TI 36x pro, but maybe a HP 300s or a Sharp EL-W535TGBBL might fufill your needs while being cheaper. But honestly if you want to go all out for a great calculator that will make you fall in love with RPN, get a HP 35s

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.

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&qid=1457070600&sr=8-1&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.

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 need a graphical calculator, when you really don't. A calculator like this is really all you need.

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.

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.

much better than ti36

My engineering buddies have told me that the preferred calculators for engineering field is Casio. This is wgat i have and it has impressed me bounds over the TI-36x. Casio fx-115ES PLUS Engineering/Scientific Calculator https://www.amazon.com/dp/B007W7SGLO/ref=cm_sw_r_other_awd_eTKxwb9D86A41

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.

The newer version

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

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

https://www.amazon.co.uk/dp/B0034BAQS8/ref=cm_sw_r_cp_api_KqiKyb5W2A10F

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

When I did it, majority of people used these.

As someone who struggled with this your advice is spot on. I'd add this, go buy this, right now. https://www.amazon.com/Casio-fx-115ES-Engineering-Scientific-Calculator/dp/B007W7SGLO/ref=sxin_4_osp48-5659e66b_cov?ascsubtag=5659e66b-b19b-4e15-a7ee-aeb0197df8eb&creativeASIN=B007W7SGLO&crid=1C44CHKHJVQOZ&cv_ct_id=amzn1.osp.5659e66b-b19b-4e15-a7ee-aeb0197df8eb&cv_ct_pg=search&cv_ct_wn=osp-search&keywords=algebra+calculator&linkCode=oas&pd_rd_i=B007W7SGLO&pd_rd_r=f8a8168c-87f4-4474-96ca-a65c1ca3a602&pd_rd_w=EdTW5&pd_rd_wg=1ve1q&pf_rd_p=a23a388c-add5-49df-b293-a31ade89c6bf&pf_rd_r=C59CRJHJSGD0Q4MKTSST&qid=1574775839&s=electronics&sprefix=algebra+cal%2Celectronics%2C143&tag=spyonsite-20

​

It does half the test for you if you know how to use it :)

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&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&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!

Many six forms around the country are asking students to get that calculator for the new A levels as you can do spreadsheets calculations on them.

The previous calculator that was widely recommended for A level was this: https://www.amazon.co.uk/Casio-null-FX-991ESPLUS-Scientific-Calculator/dp/B0034BAQS8/ref=sr_1_3?s=officeproduct&ie=UTF8&qid=1504215120&sr=1-3&keywords=casio+calculator.
This one can't do spreadsheet calculations.

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).

Buy a new one for $12: https://www.amazon.com/Casio-fx-115ES-Engineering-Scientific-Calculator/dp/B007W7SGLO

Contact Casio

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.

That's a lot of cash for a calculator that doesn't work right.

<3 my FX-115

>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).

I bought a Casio fx-115ES but never used it - the Windows calculator was so much easier to use. Also the Casio is limited to 16 binary bits in the display and the Windows calc goes to 64 bits (at least). Still, can't go wrong for $14

It's also pretty cheap

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

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.

This calculator got me through highschool and Uni. It was enough for my math and science classes, you dont need a fancy graphing calculator unless you're taking engineering or advanced math courses.

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.

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

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

​

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.

​

Saludos!

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.

​

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

 

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.
 

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.

Our physics teacher specifically instructed the invigilators for mocks to not allow them, although he is hardly the best source for information.

I think the data bank regulation actually means data you can input and store yourself, meaning you could have revision notes stored on there, rather than just constants.

The amazon listing states that the calculator is "Approved for Key stages 3, 4 and 5, recommended for Advanced GCSE, A/AS level and Highers. Allowed in every UK exam where a calculator can be used."

Seems fairly clear cut to me but the whole situation is a mess. For example, if asked to solve a quadratic equation, do you still have to do it manually and use the calculator to check? Or can you just straight up write down the solutions it gives you? Simultaneous equations? Matrix multiplication?

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 personally like this one (https://www.amazon.com/Texas-Instruments-MultiView-Scientific-Calculator/dp/B001A4G1TY). The only annoying thing is exponents, instead of a "E" button there's a "X10^." I used it for a Calculus based Physics class and it worked just fine.

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

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.

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.

Not really. https://www.amazon.co.uk/dp/B00364NNU6/ref=cm_sw_r_other_awd_BU3Qwb7XXRKZT amazon sell the same calculator for the same price.
