Question
When to proof P→Q true, we proof P false, that type of proof is known as
Solution
The type of proof you're referring to is known as "Proof by Contrapositive". In this method, instead of directly proving P → Q, you prove the contrapositive, which is ¬Q → ¬P. If P is false (¬P is true), and this implies that Q is also false (¬Q is true), then the original statement P → Q is proven to be true.
