Webmath is a math-help web site that generates answers to specific math
questions and problems, as entered by a user, at any particular moment.
The math answers are generated and displayed real-time, at the moment a
web user types in their math problem and clicks "solve."
In addition to the answers, Webmath also shows the student how to arrive at
the answer.
