Solution: Define a binary operation $+$ on $\mathbbZ$ such that for any $a, b \in \mathbbZ$, $a + b$ is the usual integer addition. Verify that this operation satisfies the group axioms: closure, associativity, existence of identity (0), and existence of inverse (for each $a \in \mathbbZ$, there exists $-a \in \mathbbZ$ such that $a + (-a) = 0$).
