The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A". Another possible notation for the same relation is {\displaystyle A i x,} A i x, meaning "A contains x", though it is used less often.where \(P\) and \(Q\) are statements. We say that \(P\) is the hypothesis (or antecedent). \(Q\) is the conclusion (or consequent). An implication is true provided \(P\) is false or \(Q\) is true (or both), and false otherwise.
