Casio fx-115es plus (fx 991es in Europe).

$17 on Amazon.

>Matrix and Vector Calculations

And it's okay to use on the FE exam if you are in a position to ever take that.

Where?? It's $75 on Amazon. I paid over $50 for mine, 6 years ago, it looks like same as yours but is a different model. These are luxuries I know a bunch of people who can't afford these.

The Casio fx-115 ES PLUS is $17 on Amazon, and has real paper-style notation, solves for x, does stats, matrices, complex numbers, tables of values, and is suitable for LITERALLY ANY HIGH SCHOOL CLASS.

I’ve been preaching to my high school students for years to drop Texas Instruments.

Imo don’t waste the money. Use tools for your phone/pc which will do a better job and stick to a scientific calculator. A lot of college courses won’t let you use graphing calculators on tests. So far I’ve had one class in two years who would allow one.

Casio has a ~$15 scientific calculator with natural display, nonCAS equation solvers, with solve vector math, systems, definite integration/differentiation, etc. great calculator allowed on pretty much all standardized testing. Also runs on solar and is smaller in size as an added bonus.

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

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.

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.

I've personally found that Casio is easier to use, battery lasted longer, less expensive, and often has more functions over other brands.. I've used this calculator for many years.. in Calculus and Algebra we weren't allowed to use Graphing calculators so this was a life saver... also it can solve for X http://smile.amazon.com/Casio-fx-115ES-Engineering-Scientific-Calculator/dp/B007W7SGLO/ref=sr_1_1?ie=UTF8&qid=1443998067&sr=8-1&keywords=casio+115

The Nspire or TI-89 are great both calculators to have for the classes that will allow it. Definitely get one or the other of those.

For everything else, I definitely recommend the Casio FX-115ES Plus. It has a lot of built in functions, it's easy to use, and (if/when you eventually get there) it is approved for the FE and PE exams.

Seriously, best calculator you'll ever own. It can do way more than i just explained, and it never seizes to amaze me.

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:

Not sure about that one, but my favorite, the Casio 115 ($15) has the ability to solve equations up to a quartic.

Technically, it approximates numerically instead of solving symbollicaly, but that's functionally equivalent.

I use a Casio FX115ESPLUS

Also, I've seen 40 dollars calculators on amazon that can do that, and I don't think they have a computer algebra system. Like this one: https://www.amazon.ca/dp/B007W7SGLO/ .

This is a great post. Thank you!

Regarding the windows calculator, I did this list awhile back. Hope it helps:

This is a cross-post from another thread seen here

With the CS271 midterm coming up and the godsend that is Windows Calculator for converting between binary, hex and decimal it's pretty awesome. However, the windows calculator doesn't have any unofficial support for signed binary. But there's a work around!

You simply need to change DWORD -> WORD for 16 bits, and WORD -> BYTE for 8 bits, then put in the binary number and now you have the signed version.

Also, it works for analyzing what number would be in a 8, 16 bit or 32 bit register.

For example, if we have the question:

The following instructions will set the Sign flag:

mov al,0FEh

sub al,2

We know the al is a 8 bit register, so if you plug in 0FEH and have the setting to BYTE, you'll see you will get 0FEH == -2. So the answer here is yes, the sign flag would be set. However, if you have the setting to WORD or DWORD OFEH == 254. And the sign flag would not be set.

I hope this helps someone :)

I apologize that I don't know how to recreate this on a Mac, but this calculator can be a possible solution

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

Casio FX-115ES Plus Scientific Calculator https://www.amazon.ca/dp/B007W7SGLO/ref=cm_sw_r_cp_apa_i_BaLnCb23B6W3A. It displays rational numbers, roots, etc. With easy conversion to decimal form. It shouldnt be allowed because you can compute derivatives and integrals, but for some reason it is.
