Proof (math)
In mathematics, a proof is a demonstration that, given certain axioms, some statement of interest is necessarily true.
Proofs employ logic but usually include some amount of natural language which of course admits some ambiguity. In fact, the vast majority of proofs in written mathematics can be considered as applications of informal logic. In the context

Proof (logic)
Proof theory, studied as a branch of mathematical logic, represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques. Proofs are typically presented as inductively-defined data structures, such as plain lists, boxed lists, or trees, which are constructed according to the axioms and rules of inference of

Truth-values
In logic, a truth value, or truth-value, is a value indicating to what extent a statement is true.
In classical logic, the only possible truth values are true and false.
However, other values are possible in other logics:
fuzzy logic and other forms of multi-valued logic
