This site is part of the MegaMath site which is a project of the Computer Research and Applications Group of Los Alamos National Laboratory. WebMath is not a database of questions and answers, or an online math testing site. WebMath is a math-help web site that generates answers to specific math questions, as entered by a user of the site, at any particular moment. In fact, currently, WebMath is of little use unless a particular math problem to solve is typed into it. You can try any problem you like and if the problem is a little difficult you can get helpful hints by following the hints link.
Complete solutions are available to teachers with e-mail addresses upon request.
