What is it?
Mathway is a Web calculator that not only solves math problems for you, but also shows you how it got to the answer with step-by-step directions. (Note: The answers are free, but Step-by-Step instructions require a fee)
Where can I get it?
Mathway is available for through standard internet browsers (
