A proof is a mathematical statement which has been demonstrated to the satisfaction of enough mathematicians of repute normally using the standard methods of mathematical logic, deduction and induction.

People will talk about axioms and rules of deduction, and say
that a proof consists of (effectively) a web of statements, each
of which is either an axiom, or the result of applying a rule of
deduction/derivation from earlier statements.

Well, perhaps, in theory, yes.

In practice, that's not how it ~works. It's much murkier.

Such a statement is then normally called a theorem.

Here is a list of pages on proofs:

* Proof by induction
* Proof by contradiction
* Proof that e is irrational
* Pi is irrational
* Root two is irrational
