There are some advanced problems that it can't slove once you go into derivatives and upper level calculus but ive never had a problem with algebraic equations.
The only thing that This app can't track down, it is word problems, love this app so dang much. It is the best Mathematical problem solving app ever. The app itself helped me threw most of my college class, simple interface, good for solving problems that most calculators don't have buttons for, and a fantastic homework helper.
It helps me ony math homework. I'm smart, but when it come to algebra I stare at the questions for a few min/hours, love this piece of software. Very helpful and simple to use, deserves all the stars. I love how it can tell numbers from people handwriting and not just print.
