If you subtract zero, you get the original number back.The reason it is not usually considered the "identity element of subtraction" is that the base operations are addition and multiplication - subtraction and division are simply the inverse operations to addition, and multiplication, respectively. When defining numbers in an axiomatic system, the emphasis is on those base operations.

The identity element must commute with every element in the set under the relevant operation. However, x - 0 = x while 0 - x = -x for any element in the set.

What is the identity element for addition and subtraction?

0, zero, is defined as the identity element for addition and subtraction. * * * * * While 0 is certainly the identity element with respect to addition, there is no identity element for subtraction. The identity element of a set, for a given operation, must commute with every element of the set. Since a - 0 ≠ 0 - a, according to group theory, 0 is not an identity with respect to subtraction.


What is identity in math?

In mathematics, identity is a transformation that leaves an object unchanged. In addition and subtraction, the identity element is zero. Adding or subtracting zero to or from a number will leave the original number. In multiplication and division, the identity element is one. Multiplying or dividing a number by one will leave the original number.
