Casio fx-991ES Plus C 2nd Edition CalculatorGreat calculator that is budget friendly and has everything your child needs to get thru highschool. The display is dot matrix so it gives really nice output of functions formulas and placement. Buttons are a bit cheap feeling and not too tactile. sometimes pressing the key doesnt register when youre punching in numbers quickly. Built-in metric conversions are handy -- theres a reference chart on the cover of the calculator. Contrast is a bit wonky to read out by default so make sure you adjust contrast in setup.I'm not about to list out all the functions of this calculator... you can read the product page for this.Good high function complex display calculator great for highschool and university if you get there. Honestly this stuff used to be 100$ back when i grew up but now its so affordable.

The Casio FX-991-ES plus C 2nd Edition is the best non-programable scientific calculator at present time. Although it has 417 functions and slightly slower processor than the FX-991-EX 552 functions, it is physically more stable on flat surfaces, the buttons feel better and the font size is better, and it is more practical in speed of keystrokes when solving different levels of math problems. It is also, better when taking tests than the new FX-991-CW which requires many more keystrokes and switching consistently between settings, catalog, and the tools functions to solve the same simple and complex problems, and the FX-991-CW has problem when dividing in scientific notation where the wrong answer will be given if the number in the denominator is not placed in parentheses where this is not the cast with the Casio FX-991-ES plus C 2nd Edition.

Excellent calculator for the price. It can do unit conversions, and solve quadratic problems. Only drawback is that the buttons are a little hard to press, and the protective case is loose

It’s a light weight powerful calculator, good enough for school and university.
It comes in a box package. It’s authentic Casio product. Genuine Casio. It does not support 4x4 Matrix calculations like mentioned in description.
There is a bug with complex mode … i^4 will throw a math error but iiii would give 1 as answer.

It is a very good non-programmable calculator for first and second year students. It is has quite a bit of complexity functionality and a pretty easy-to-use interface. I wished the calculator allowed me to use +2 lines at a time though (e.g. a 6 line display). But I feel like you can only find big displays in programmable calculators (which can't be used for most university courses)

This is definitely a great calculator that has helped me get through my grade 12 advanced functions course. I find it very useful and easy to navigate and has multiple useful functions. I was actually recommended this calculator by a friend who took the math class the previous semester and I’m so thankful she did!
