For years I have been using MathCad, which is an excellent application for computational purposes.

I was recently given Mathematica and just installed it. I know that Mathematica is a better product, but it seems user hostile compared to MathCad.

When I first started using MathCad, I just hacked it without the manual. I do not seem to be able to do that with Mathematica.

Does anybody have any opinion on these two products?
