In mathematics, a binary operation <math>*</math> on a set '''A''' is said to be commutative if for all <math>x,y</math> in '''A'''  we have <math>x*y=y*x</math>. An Example of a commutative operation is addition in the [[real numbers]]. When a [[group (mathematics)|group]]'s operation is commutative, it is said to be [[Abelian]]
