Equivalence refers to a relationship between two propositions or statements where they hold the same truth value in every possible scenario. This concept is essential in propositional logic, as it allows us to establish when two statements can be considered interchangeable based on their truth conditions, often represented by logical operators like 'if and only if' (iff). Understanding equivalence helps in simplifying complex logical expressions and reasoning about the validity of arguments.
