comment is this a foolish way to do proofs?
Say you're given some axioms and some basic identities and you're asked to prove the validity of some equation. For example, the triangle inequality. The first approach I described would be to start with $|a + b|$ and to apply those axioms and identities to generate a more elaborate equation. The result is I'm trying to prove is $|a + b| \leq |a| + |b|$.
