The '''multiplicative''' identity for a ring or field is the element, ''i'', of the set that, when multiplied by any element ''a'' in the set yields an answer of ''a''. In the [[integers]], [[rational numbers]], and [[real numbers]], the multiplicative identity is 1. For the [[complex numbers]], the multiplicative identities are the roots of 1.
