Is there any integer which does not have zero as its additive identity?
No
If a is an integer, then a+0=a
So, 0 is the additive identity of all integers. There is no integer which does not have zero as its additive identity.
If a' is any integer then a+0=------------- = --------------
Name the additive identity.
Is there an integer which is its own additive inverse?
Statement 1: 0 is the additive identity for integers.
Statement 2: Any integer added to zero results in the integer itself.
