Derivation Rules for Propositional Logic The derivation rules for propositional logic fall into two categories, equivalence rules and inference rules. Equivalence rules allow individual wffs to be rewritten, while inference rules allow new wffs to be derived from previous wffs in the proof sequence. • Equivalence Rules:
