I must admit I'm a very math-challenged person. Numbers were my main weakness at school and even nowadays I have problems to check if my change is correct when I'm shopping. But this doesn't mean I can't appreciate a tool like Math Solver.

This amazing program helps you solve all kinds of mathematical problems, from a simple addition to a complicated geometrical function. Not only does it solve the operation, but also draws a graph based on it if possible, and gives extra information about the generated graph. The program also includes an excellent database with constants and functions.

On the downside, I think Math Solver is not really comfortable to use. Solving expressions and representing functions take too many clicks. Also, as each piece of information is offered in a separate window, your desktop can get really messy. Besides, Math Solver keeps a history of previously entered expressions so that you can review them or reuse them at any moment, but unfortunately they're not saved when you quit the program.
