, 12:15, September 3, 2008I know what a binary operation is, but how many of our readers do?

In mathematics, the '''commutative property''' states that 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]].
