# With sage cell server implement an automatically generated and automatically checks the job in algebra or calculus.

Hello! I have a problem. How to organize a dialogue with the user? So that he could enter a reply, and the server gave the answer: right or wrong. On the example of computing the determinant of a matrix. The following quote program listing.
