In mathematics, a ring is an algebraic structure consisting of a set together with two operations: addition (+) and multiplication (•).These two operations must follow special rules to work together in a ring. Mathematicians use the word "ring" this way because a mathematician named David Hilbert used the German word Zahlring to describe something he was writing about.

In mathematics, rings are algebraic structures that generalize fields: multiplication need not be commutative and multiplicative inverses need not exist. In other words, a ring is a set equipped with two binary operations satisfying properties analogous to those of addition and multiplication of integers. Ring elements may be numbers such as integers or complex numbers, but they …

A ring is a set equipped with two operations (usually referred to as addition and multiplication) that satisfy certain properties: there are additive and multiplicative identities and additive inverses, addition is commutative, and the operations are associative and distributive. The study of rings has its roots in algebraic number theory, via rings that are generalizations and extensions of ...
