There is no such thing as an "identity of element". The identity element of multiplication, on the other hand, is the number 1.

1 is the identity element of multiplication. What this means is that if you multiply any number by 1, the result is the same as the original number.

The multiplicative identity of a number leaves that number unchanged under multiplication. Thus the multiplicative identity of any number is 1.

The identity element of multiplication is the number 1. It means that if you multiply any number by 1, you get the same number back again.

1 is the identity element of multiplication.

An identity element is an element of a set which leaves other elements unchanged when combined with them. For multiplication, the identity element is 1 .

0 and 1 are both identity element. 0 is the identity element of addition and its called addend while 1 is the identity element of multiplication it is called factor it can be neither multiplier nor multiplicand.

That is because 1 is the identity element of numbers with respect to multiplication.

If you mean in the group {1, -1, i, -i, j, -j, k, -k}, the identity element is 1.

1 is the identity element over multiplication and division.

No. The identity for addition is zero; the identity for multiplication is one.

They both considered "identity elements". 0 is actually the identity element under addition for the real numbers, since if a is any real number, a + 0 = 0 + a = a. Mathematicians refers to 0 as the additive identity (or better said, the reflexive identity of addition). 1 is a separate and special entity called 'Unity' or 'Identity element'. 1 is actually the identity element under multiplication for the real numbers, since a x 1 = 1 x a = a. Mathematicians refers to 1 as the multiplicative identity (or better said, the reflex identity of multiplication).
