Binary Operator
An Operator defined on a set 
which takes two elements from as inputs and returns a single element of .Binary operators are called compositions by Rosenfeld (1968). Sets possessing a binary multiplication operation include theGroup, Groupoid, Monoid, Quasigroup, and Semigroup. Sets possessing both a binarymultiplication and a binary addition operation include the Division Algebra, Field, Ring, Ringoid,Semiring, and Unit Ring.
