WebMathematical statements are often indicated using capital letters. For example, we might describe the statement ‘five is less than eight’ by writing P: five is less than eight. The negation of P, symbolized by ∼ P, is the statement having the opposite truth value. That is, when P is true, ∼ P is false and when P is false, ∼ P is true.

WebJan 8, 2024 · Sorted by: 0. The truth table for conditional P Q (you can find this online) tells us that the conditional P Q is false if P is true and Q false; otherwise it's true. So your counterexample has to be a case where P holds, but Q does not. In your example, x = − 6 works as a counterexample. x = 6 is true, but x = 6 is false; thus x = 6 ...
