I guess there is a good reason not to simplify symbolic expressions by default. As I said in my previous post: Provided that all your examples are with matrices whose coefficients are polynomials, your students should simply work with matrices over a polynomial ring. Such as: sage: P.<x> = CC[] sage: A=matrix([(x+1)*(x-1)]); B=matrix([x^2-1]) sage: A == B True Of course, the matrices would then not have a simplify_rational method. Generally, it seems to me that one should use the symbolic ring only when really needed.
