What is negation?

Negation is the act of denying or refuting a statement or proposition. It is the opposite or absence of something. In logic and mathematics, negation is often represented by the symbol "~" or "¬".

Negation is the logical operator that reverses the truth value of a proposition. In other words, it is the operator that makes a true proposition false and a false proposition true. The negation of a proposition is denoted by the symbol ¬, which is placed before the proposition. For example, if P is the proposition "It is raining," then ¬P is the proposition "It is not raining."
