In trying to rebuild an expression piece by piece, I have generated the following expression:
>>> Add(*[Pow(*[y,2],evaluate=True),Mul(*[-1,Pow(*[y,2],evaluate=True)],evaluate=True)],evaluate=True) y**2 - y**2 >>> What do I need to do at this point to get it to go to zero? -- You received this message because you are subscribed to the Google Groups "sympy" group.
