This is called the identity property of division. a number times 0 = 0 100*0=0. Examples : We have seen that the Euler totient function \(\phi\) is mulitplicative but not totally multiplicative (this is one reason it is convenient to have \(\phi(1) = 1\)). By transitivity of equality, we have 1 =10. Definition of. No. ----Have Instagram? The multiplicative identity is a common occurrence in advanced algebra.

In mathematics, an identity element, or neutral element, is a special type of element of a set with respect to a binary operation on that set, which leaves any element of the set unchanged when combined with it. The number 1 is, in fact, the multiplicative identity of the ring of integers and of its extension rings such as the ring of Gaussian integers , the field of rational numbers , the field of real numbers , and the field of complex numbers . Multiplicative identity definition, an identity that when used to multiply a given element in a specified set leaves that element unchanged, as the number 1 for the real-number system. It is also called the Identity property of multiplication, because the identity of the number remains the same. For example, 4 is the multiplicative inverse of 1/4 because 4 × 1/4 = 1.
