>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"...

$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 (:

I must have been a bit unclear in my wording. One of the main reasons for my complaints is that I want a calculator that is faster and has a higher resolution. We both already agree, then, that the EX series is newer, faster, and has a higher resolution screen than the ES series. Anything I wrote on that subject is meant only to confirm those facts with hard evidence and to show more-precisely how much faster the EX series is than the ES series, rather than leaving the answer a vague "faster". It turns out the EX is about 5 times faster than the ES.

As a mathematics and computer science graduate who often tutors students ranging from fifth year elementary maths to linear algebra and number theory, I use almost all of the functions on the 115es plus at different points. I enjoy keeping my maths knowledge intact by doing some calculations or solutions on paper or in my head and using my calculator to confirm my results or tell me I'm wrong, which includes something as simple as finding the prime factorization of a somewhat large integer or finding the product of a series. Those are but two of many (literally hundreds, as mentioned in my post) examples of what the fx-115ES Plus can do that the US fx-991EX can't do at all. I can get around some of those by converting the products to sums but that's a huge extra step on my part and also hardly worth doing since those will take a very long time on the calculator. I like to go to the library on weekends and study "How to Solve It: Modern Heuristics", which covers various areas of maths, and getting through all tedious calculations by using my cheap scientific calculator or confirming the soundness of my more symbolic results by doing a few quick inexact calculations. That's why I would LOVE the fx-991EX to do all that my old fx-115ES Plus can do. I also hate worrying about the battery life of my graphing calculators and having to recharge them. I hardly have to worry if I've been doing tens of hours of calculations on my scientific calculator for weeks on end, but often have to get new batteries for my TI-89 or have to recharge any of the newer ones. I'm honestly really tired of always having to worry about recharging my mobile and other devices as well.

I have a similar philosophy for other devices, like my MP3 player, the SanDisk Clip+. I got it when it was cheap, not $100 as it is now due to scarcity. After I switched its operating system to RockBox, which makes it able to play all sorts of audio files and added tons of functionality like a highly-customizable equalizer, I had a very simple device that could do everything I wanted. I don't care about fancy colors and album art or touchscreens on a simple audio player. All that stuff breaks and uses more power anyway. All I care about is that it's powerful enough to do all the real things I want it to do, not pointless fancy graphical things meant only for marketing purposes that are detrimental overall.

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

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.

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.

Short answer: HP 39gs.

Long answer depends on a few more things:

  • What do you plan to study in college? Will you need the calculator for calculus? engineering? computer science? linear algebra?
  • Do you need to be able to use it on any particular standardized tests?
  • Do you have any experience or familiarity with other calculators?
  • Do you know how to program? Do you want to know how to program?
  • Can you figure out how to do things on the calculator on your own with the manual, or do you need your teacher or textbook to demonstrate?

If you only need a scientific calculator, the Sharp W516X / BSL has 4 assignable buttons at the top (D1-D4) ;) Plenty of room there to stick your own labels on (there is a newer model available too, but the D1-D4 custom keys have been moved down with the rest of the others).

I disassembled my TI 84+ Silver edition, and found a single PCB supported by a gratuitous amount of plastic. If you put one of these on it, I imagine it wouldn't get much better for durability.

HP 35S 35S Programmable Scientific Calculator, 14-Digit LCD https://www.amazon.com/dp/B004A0XHH4/ref=cm_sw_r_cp_api_i_ssjwDbAX34RV2 this one? Ive been eyeing it for a minute

u/ohitsanazn · 1 pointr/calculators

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.

If you're allowed a little programming, the HP-35s is excellent.

It isn't a graphing calculator, but it does have some programmability, so it may not be alright for your classes.

If you're looking for a bare-bones scientific calculator, you could do worse than the TI-36XS Pro.
