no, 0, anything minus 0 is still whatever it was.
0 is the identity
Subtraction is not an identity property but it does have an identity property. The identity is 0 and each number is its own inverse with respect to subtraction. However, this is effectively the same as the inverse property of addition so there is no real need to define it as a separate property.
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.
Yes it is.
minus
It is 0.
The minus sign.
It is the "additive identity".
The question does not make sense.

No. Subtraction is not commutative.No. Subtraction is not commutative.No. Subtraction is not commutative.No. Subtraction is not commutative.
If you subtract 0 from any number, that number remains unchanged. Hence, the identity of the number is preserved.
