About “¬”
Logical 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.
So, if statement A is true, then ¬A (pronounced “not A”) would therefore be false; and conversely, if ¬A is true, then A would be false.
