In mathematics the additive identity of a set which is equipped with the operation of addition is an element which, when added to any element x in the set, yields x.

Description

One of the most familiar additive identities is the number 0 from elementary mathematics, but additive identities occur in other mathematical structures where addition is defined, such as in groups and rings.
