0
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.

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.

What is Identity element of subtraction of rational number?
It is 0.
What is the identity element for subtraction?
The minus sign.
What is the number zero called for addition and subtraction?
It is the "additive identity".
Is zero the identity number for multiplication?
No. Zero is the identity element of addition. One is the identity element of multiplication. That means that adding zero, or multiplying by one, doesn't change the number.
The identity element for addition is a?
Zero.
What is the identity element for addition?
Zero.
What kind of integer is zero?
zero is the additive identity element.
The identity element for addition is 1?
No. The identity for addition is zero; the identity for multiplication is one.
