What is the multiplicative identity element in the set of whole numbers? In mathematics, the additive identity of a set that 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 The "Additive Identity" is 0, because adding 0 to a number does not change it: a + 0 = 0 + a = a. 7.
