Using this as a guide, we define the conditional statement P → Q to be false only when P is true and Q is false, that is, only when the hypothesis is true and the conclusion is false. In all other cases, P → Q is true. This is summarized in Table 1.1, which is called a truth table for the conditional statement P → Q.3 Answers. The ⇒ notation means that if the function on the left hand side of the notation is true, then so is the function on the right hand side of the notation. So consider X ⇒ Y. This means that if X is true, then Y is also true.
