What is Binary operation?
In [[mathematics]], a '''binary operation''', often shown as *, on a [[set]] is a way of combining a pair of elements in that set that results in another element of the set. For example, if we take a pair of [[natural number]]s and let the operation * be addition, then their [[sum]] is also a natural number, and is the result of applying this particular binary operation. Another example of an operation on the natural numbers is [[multiplication]]. For instance, take the natural numbers 2 and 3. When multiplied together they give 6, another natural number. Others: The sum between [[Matrix (mathematics)|matrices]]. The composition of [[Function (mathematics)|functions]]. The [[Set|union]] and the [[intersection]] of sets are also two different binary operations on the set of all sets, or on subsets in a [[power set]]. == References == [[Category:Mathematics]]
