Pearson's MyMathLab, a widely used course management system for math classes costs each student approximately $85.50. Though many students purchase used textbooks, they still must pay the full price for access to MyMathLab. MyOpenMath was created by a mathematics faculty instructor who wanted an open source that could be used instead of MyMathLab. MyOpenMath is free to students and to faculty educators.
