WebWherever logic is applied, especially in mathematical discussions, it has the same meaning as above: it is an abbreviation for if and only if, indicating that one statement is both necessary and sufficient for the other. This is an example of mathematical jargon (although, as noted above, if is more often used than iff in statements of definition). WebInstead, we can discern the meaning of “if and only if” using our already rigorous definitions of “if”, “and”, and “only if”. Specifically, “ P if Q and P only if Q ” will be translated “ ( (Q→P)^ (P→Q)) ”. (If this is unclear to you, go back and review section 2.2.) Now, let us make a truth table for this formula. P.

WebSince implications are not reversible, even though we do have \(27=27\), we cannot use this fact to prove that \(21=6\). After all, an implication is true if its hypothesis is false. Therefore, having a true implication does not mean that its hypothesis must be true. In this example, the logic is sound, but it does not prove that \(21=6\).
