Perfect for my AP Calculus homework. The matrix operations saved me on my final exam! The graphing feature works exactly like my teacher's TI-84.

I use this for classroom demonstrations. My students love that it's free and works on their phones. The interface is identical to the physical TI-84 Plus CE.

Way better than buying a $120 calculator. Works offline and has all the functions I need for statistics. The statistics suite is particularly impressive.
