IMathAS is a web-based math assessment and homework system. It is a course/learning management system (CMS/LMS/VLE) and testing system featuring algorithmic questions, similar to WebWork, Webassign, and publisher systems like iLrn, MathXL, etc.
The code in this project is incomplete and buggy in parts. It has been superseded by the math packages I wrote for PEAR (pear.php.net). Use those instead (see the Math section of the packages list). -- Jesus M. Castagnetto
