Sometimes I think Mathematica might better be called MetaMathematica, not so
much a tool for doing mathematics but a tool for making the tools to do
mathematics.

Quite often it will be very useful to "combine and repackage" Mathematica
procedures into forms that are more natural and convenient for your
application. Writing some definitions and functions along these lines can be
very useful. You don't have to limit yourself to the hooks and buttons that
are manifest in plain Mathematica.

Maybe there's a mathematical reason why simple operations on equations
aren't handled as I'd expect. Mathematica is clearly a powerful tool, but
the few times I've tried picking it up in the past I wind up getting stymied
by the obtuse syntax for certain simple operations.

In this case, I could probably use the power of the tool all at once by
simply treating my set of equations as a unit and asking Mathematica to
reason about them as a group and solve my problem directly. The problem is
that I, and my audience, could probably gain some insight into the problem
by working through a few of the intermediate results. By treating my
equations lexically, rather than mathematically, I'm forgoing Mathematica's
expertise and only allowing it to ensure I don't make transcription errors.
