SpletIn logic and mathematics, the logical biconditional, sometimes known as the material biconditional, is the logical connective used to conjoin two statements P and Q to form the statement "P if and only if Q", where P is known as the antecedent, and Q the consequent. This is often abbreviated as "P iff Q ".Other ways of denoting this operator may be seen … SpletThe biconditional connective p ↔ q is read “p if and only if q.” Here's its truth table: T F F T p q p ↔ q F F T T F F T T One interpretation of ↔ is to think of it as equality: the two propositions must have equal truth values.
