Propositional logic uses normal and principal forms to standardize complex statements

Propositional logic uses normal and principal forms to standardize complex statements for easier analysis and manipulation. These forms break down logical expressions into structured combinations of literals, using operators like AND, OR, and NOT. Common types include Disjunctive Normal Form (DNF) and Conjunctive Normal Form (CNF). Principal forms, like PDNF and PCNF, offer canonical representations using minterms or maxterms derived from truth tables, ensuring logical equivalence and simplification.
