ASCII Character ¬
NegationClassical negation is an operation on one logical value, typically the value of a proposition, that produces a value of true when its operand is false, and a value of false when its operand is true. Thus if statement P is true, then ¬P (pronounced "not P") would then be false; and conversely, if ¬P is false, then P would be true.
