In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation.
A semigroup generalizes a monoid in that there might not exist an identity element.
It also (originally) generalized a group (a monoid with all inverses) to a type where every element did not have to have an inverse, thus the name semigroup.
