TI-36X Pro Scientific Calculator (Bulk Packaging)

MUCH more than any other scientific calculator

I'll keep this brief, but know that I love this more than my graphing calculators. It is closer to one of those than a scientific calculator, and usually faster, funnily enough. It can do up to 3rd degree polynomial coefficient solving, linear homogeneous equation solving, 3x3 matrix math, common scientific constants and unit conversion, complex numbers and vector math, simple derivatives and integrals, a bunch of various math functions, simple statistics calculations, and a LOT more. Also the mathprint notation makes fractions a breeze, I often use it over my graphing calculator for that reason. My only slight gripe is that this company didn't send me the quick reference sheet that goes in the cover and user manual with the calculator. Both are a google search away, and the user manual is actually worse than a lot of good guides online, but I am slightly sad about that reference sheet. If that is my only complaint, then you know the calculator is good.
