In logic, a negation of a simple statement (one logical value) can usually be formed by placing the word "not" into the original statement. The negation will always have the opposite truth value of the original statement. ... Negation -- NOT--; Simple Statements; Topic Index | Geometry Index | Regents Exam Prep Center...

We consider two ways of thinking about negation: (i) as a form of complementation (the negation of a proposition p holds exactly in those situations in which p fails), and (ii) as an operation of reversal, or inversion (to deny that p is to say that things are the other way around). ...

In mathematics, Euclidean geometryis the familiar kind of geometry of at most three dimensions; ... Other mathematicians proposed that the statement was indeed a postulate, and tried to prove their suggestions, by "negating the postulate" (call the negation NOT P) as an axiom, hoping to arrive at a contradiction.
