(x+y) is equivalent to (y+x): launching mathematical expressions checking - 2 views

Garrett Eastman on 25 Sep 12"Several of our classes involve students using mathematical expressions, but there was no way for us to automatically check this work. The stated solution to a problem may be x+y, but if a student answers y+x, our system needs to understand that this is also correct." "sympy, an open source Python library for symbolic mathematics," is proposed as a solution.
