To give the set closure with respect to subtraction, or to give it an additive identity.
1 is an additive identity
no 1 is not an additive identity
There is only one set and it does have an additive identity.
Additive identity: zero. Multiplicative identity: one.
It is the additive identity.
The additive identity for rational, real or complex numbers is 0.
additive inverse is when in an equation there is a plus zero. you automatically know that anything plus 0 is still that number, so that is additive identity.
No, it is not.
0 is the identity
