Reddit mentions: The best scientific calculators

>Agree that all three of those calculators are solid choices.

These are good times to be in the market for a scientific calculator. If the OP has $54 to spare he could buy all three. For $37 he could try your favorite and my favorite.

If his budget is really tight, he can still get a pretty good name brand calculator for under 10 bucks:

Texas Instruments TI-30Xa $8.99

https://www.amazon.com/dp/B00000JBNS/

Casio FX-260 SOLARII $8.47

https://www.amazon.com/dp/B071R3H9WB/

Sharp EL-501XBGR $7.23

https://www.amazon.com/dp/B004TS0GR6/

Of the above three I like the TI the best. Whoever designed the TI-30Xa really "gets it" when it comes to making the things you use a lot be unshifted.

Or he could try the cheapest scientific calculator on Amazon and learn the valuable lesson "you get what you pay for"...

https://www.amazon.com/dp/B07GCBT5JN/

$3.50 with free shipping if you have Amazon Prime. Then another $3.50 in two weeks when the keys fall off and you wish you had bought the TI-30Xa (:

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).

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

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.

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!

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.

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.

-----

These two are very useful non-graphing calculators for cheap (just under $20/each):

https://www.amazon.com/Texas-Instruments-Engineering-Scientific-Calculator/dp/B004NBZB2Y/

https://www.amazon.com/Texas-Instruments-34MV-TBL-1L1/dp/B001A4G1TY/

But before you drop $50-150 on a sexy Graphing Calculator, make sure you'll be allowed to use it.

It's partly because I'd like to be able to just pick one up from the store at a very inexpensive price that does everything my fx-115 es plus does. I have more-powerful graphing calculators, but would like a cheap one I can take everywhere without worrying about having it stolen or broken, as well as having a longer battery life than any graphing calculator has. The much faster (according to benchmarks) and aesthetically more-pleasing fx-991ex would have filled that need for me. The aesthetics matter in this case since I can easily see more information on the screen at once and have to scroll less often if at all in order to see a longer formula. However, the 991EX (US) lacks lots of functions that made its predecessors of 6 or 7 years here stand out. I know for certain that the Japanese version has even more functions (by a small margin) than the German version and can be switched to English, but it would be three times as expensive for me to acquire as well as requiring wait time for it to arrive. The whole point was to be able to find a calculator that can easily be replaced that I can take everywhere that is at least as good as the one I have with an updated processor for more-quickly making intensive calculations and that's even easier to use due to a display that can contain more information.

Note: Just to confirm that the ClassWiz series is significantly faster than what I have, I watched this video and performed the same calculation on my fx-115ES Plus. While my 115ES Plus, at 2 minutes 58 seconds, was 30 seconds faster than the 991ES, it was vastly outperformed by the 991DEX, which only took 36.8 seconds in total. The ClassWiz series, it seems, is about 5 times faster than what I have according to that example.

Hello! Thanks for the contest!!

On my list I have "Victor 940 Advanced Scientific Calculator" and here is a [link](Victor 940 Advanced Scientific Calculator https://www.amazon.com/dp/B01FUT8JPS/ref=cm_sw_r_cp_api_7hXsybC6R5H60)

I've been teaching myself math so that I can return to school. I've been using the website Kahn Academy to study all of math from elementary and up. I'm pretty far in my progress(feels so good to say that!!!)and soon I'll be needing a more scientific calculator.


Happy holidays and hats off to you!

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.

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.

This has been my go to lol buttons feel nice and it's small so it can fit in my pocket sometimes easily

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.

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

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've got this one and I love it!
http://www.amazon.com/CASIO-Scientific-Calculator-FX-991ESPLUS/dp/B0034BAQS8/ref=sr_1_2?ie=UTF8&qid=1465072255&sr=8-2&keywords=Casio+FX-991

It's also pretty cheap

Interesting, it's literally the exact same calculator! Lol
Found this on Amazon AU https://www.amazon.com.au/dp/B0089QSATA/ref=cm_sw_r_cp_awdb_c_MR3VCbJWN7Y17
It's on the list, and they seem to be shipping it to the UAE.
Search amazon for the 100AU, it doesn't pop up for me for some reason.

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

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

Not certain it counts, but i've used my TI-30 nearly every day since I bought it and it's been nothing but perfect to me. Little big for a pocket carry, but if you're lugging around a bag it's definitely one of the most useful items I can think of.

I own this one in blue:

http://www.amazon.com/Texas-Instruments-30XIIS-TBL-1L1/dp/B007HIVMBO/ref=sr_1_13?ie=UTF8&qid=1381364027&sr=8-13&keywords=ti-30

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.

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?

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

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).

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 used this for applied calculus Casio fx-115ES PLUS Engineering/Scientific Calculator https://www.amazon.com/dp/B007W7SGLO/ref=cm_sw_r_other_awd_eTKxwb9D86A41

I've since recommend the calculator to friends and most of them concerted to Casio because of the calculator.

Bunch of used one on Ebay under $20. Free shipping too....

A new TI-36 is $18 on Amazon. What can the 85 do what the 36 can't?

Or just switch brands:

http://www.amazon.com/Casio-fx-115ES-Engineering-Scientific-Calculator/dp/B007W7SGLO/ref=sr_1_11?s=office-electronics&ie=UTF8&qid=1426431440&sr=1-11&keywords=calculator

>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).

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

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.

For a non-programmable calculator: I loved the Sharp EL-W535B WriteView during undergrad.

http://www.amazon.com/Sharp-EL-W535B-WriteView-Scientific-Calculator/dp/B000RZDSWK

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.

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.

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.

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.

https://www.amazon.ca/Casio-FX-115ES-Plus-Scientific-Calculator/dp/B007W7SGLO/ref=pd_cp_229_2/145-3695051-5130712?_encoding=UTF8&psc=1&refRID=45VGAMTQ1QVYZE6ZADVJ

Works good. They sell it with the Eng sticker in the bookstore

much better than ti36

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

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

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.

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

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

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 :)

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.

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.

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

OR

Contact Casio

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

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.

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

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

The newer version

When I did it, majority of people used these.

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.

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

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

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

<3 my FX-115

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.

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

http://smile.amazon.com/gp/product/B007W7SGLO?psc=1&redirect=true&ref_=oh_aui_search_detailpage

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

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

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.

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.

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.
