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.

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.

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
