Binary Composition:
Let A be a non- empty set . A binary composition (or a binary operation) on A is a mapping f:A×B--->A. Therefore binary composition f assigns a define element of A to each ordered pair of elements of A . This mapping f is generally denoted by the symbol "o". For a pair of element a,b in A,the image of (a,b) under the binary composition o. is denoted by. aob. The image of the element (b,a) is obviously boa.
The symbol like *,+ are also used to denote a binary composition.
