Yes.
Verified.
Identity: 0....x+0= 0+x=x for all x
Closure: x+y is aninteger when x and y are
Associativity: (a+b)+c= a+(b+c) ...check
Cummutativity: a+b = b+a
Inverse: a+(-a) = 0
check check check
Unless of course you are going back to the basic basics where you do that define an integer ala Bourbaki. Hmmmm......

An abelian group must have the property that a + b = b + a for all a,b in the set of integers.
It seems easy enough, but you'll probably need to take a closer look at the definition of addition, first.
