Logical negation
(Redirected from Logical not)
Logical negation (also known as not) is a logic operation. For a proposition [math]\displaystyle{ P }[/math], its negation is written as [math]\displaystyle{ \neg P }[/math].[1] It takes one input. It flips the value of the input as the output. If the input was true, it returns false; If the input was false, it returns true.[2][3]
