USER REVIEWS "This program has an incredible amount of power for such a compact program. I teach high school math, and this program can work with all sorts of expressions, graphs, and help check my work. Definitely worth it!" "You will love this calculator. It's powerful to calculate everything, doesn't matter you're a high school student or college student. Specially for the people who like to solve problems with graphs!" "This app is so powerful and slick looking. It is totally amazing and what it can do." "One of three Apps I use when teaching A Level maths. Have recommended to numerous students. Excellent." "This is one of the best. The CAS capabilities are compatible to only two other apps, and this one is all offline and includes countless additional features. It's never steered me wrong and is the first thing I go to when I'm in a hurry to figure something out. If you're a student this is pretty much as good as it can get." "I am 8 years old and this App is awesome! It helps you learn calculus quickly. It's a work of art!"
