Additive identity Additive identity 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". 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. Let "N" be a set which is closed under the operation of addition, denoted +. An additive identity for "N" is any element "e" such that for any element "n" in "N", Example: The formula
