= Propositional proof system
{wiki=Propositional_proof_system}
A **propositional proof system** is a formal system in mathematical logic that is used to establish the validity of propositional formulas. It consists of a set of rules and axioms that allow for the derivation of logical statements from other statements. The goal of such a system is to demonstrate that certain propositions can be proven true based on established truths, regardless of the specific interpretation of the involved propositions.
