 | | In mathematics, a proof is a demonstration that, assuming certain axioms, some statement is necessarily true. |
 | | The distinction between formal and informal proofs has led to much examination of current and historical mathematical practice, quasi-empiricism in mathematics, and so-called folk mathematics (in both senses of that term). |
 | | Proof by construction: (also known as proof by example) constructing a concrete example with a property to show that something having that property exists. |
