What IMathAS is
IMathAS is a web-based system for creating and grading mathematics homework and tests. Instructors can use algorithmically generated questions and have numerical answers and mathematical expressions graded by computer. Assessment formats include multiple choice, matching, essay, matrix, interval, graphing, file upload, and multipart questions. Math display, calculator-style entry, and point-and-click graph creation support math-focused work. Course tools include announcements, text items, attachments, discussion forums, and a gradebook. Instructors can share questions through libraries and export or import question sets between systems. IMathAS supports LTI 1.1 as both a consumer and a producer. It can be used on the web or installed on a web server; self-hosting requires PHP 7.4 or later and MySQL 5.7 or later. The software is free and open source under the GNU Public License. The maker says it is designed for math assessment, not as a multipurpose platform. Documentation includes training videos, use and question-writing guides, and detailed feature references. There is no official support or warranty.
