Preposition Logic – Negation of a Statement


If p is a statement , then the negation of the statement is negative of the statement. Suppose p is “I am hungry” .

The negation of the statement is “not p” where not is the negation operator.

p:  I am hungry.

not p : It is not the case that I am hungry or I am not hungry.

There is another way we can represent the negation operator.

p is the simple preposition, then \neg p is negation of the statement p . We have to be careful about the negation operator.
