When I have given introductory Mathematica courses, one of the things I
would point out early on, was that you should never implicitly trust
Mathematica to get an answer that was important to you.

By that, I did not mean what you seem to mean - that Mathematica was
particularly buggy - because it is not, but every substantial piece of
software contains some faults, and fingers contain bugs too - so it is
easy to mistakenly type something like:

Integrate[Exp[ax]x,x]

and be be amazed by the answer. Likewise, systems of equations can be
numerically unstable and generate junk.

It might almost be better to train students on slightly faulty software
to make them more vigilant!
