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.
