Propositional calculus

In mathematical logic, a propositional calculus or logic is a formal system in which formulae of a formal language may be interpreted as representing propositions. A system of inference rules and axioms allows certain formulae to be derived, called theorems; which may be interpreted as true propositions. The series of formulae which is constructed within such a system is called a derivation and the last formula of the series is a theorem, whose derivation may be interpreted as a proof of the truth of the proposition represented by the theorem. Truth-functional propositional logic is a propositional logic whose interpretation limits the truth values of its propositions to two, usually true and false. Truth-functional propositional logic and systems isomorphic to it are considered to be zeroth-order logic.
