Auto-simplification: CAS does, Calc Suite doesn't
In the CAS Calculator, if I define f(x) = (x^2-1)/(x-1), it automatically simplifies to x+1, and if you compute f(0) you get 1.
In the Calculator Suite, making the same definition, there's no simplification done and f(0) is undefined (as it should be).
Why the difference? Why does the CAS auto-simplify? Can I turn that off?
