Except instead of clothes, we have mathematical formulas. All the steps follow the rules of logic and induction. Since they are more highly patterned than most proofs, they are a good place to start. As such, proof theory is syntactic in nature, in contrast to model theory, which is semantic in nature. Use rules of inference, axioms, and logical equivalences to show that q must also be true. Proof theory is a major branch of mathematical logic that represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques. Hopefully we won't get chilly walking down the runway. The proofs we've looked at so far have been all about directly proving something is true. Direct Proof: Assume that p is true. Given a few mathematical statements or facts, we would like to be able to draw some conclusions. The definition of mutually exclusive with examples.
