MathCheck examples

The purpose of MathCheck is to help students learn high school and early university mathematics. The student can type in or copy and paste a solution to a problem. MathCheck shows the solution in mathematical notation and partially checks it. With MathCheck, students can get some useful feedback on their solutions and thus improve them before delivering them to a human teacher.

MathCheck is currently under development. Please feel free to try it as much as you like, but please do not start serious use without asking me first. If you find a bug in MathCheck, please tell me.
