When talking about vector space, you usually need the "scalar (field)", and scalars need inverse to be well-defined.

So for integers, the scalar should be integer itself. Sadly, inverse of integers stops being an integer, ~~from where all sorts of number theoretic nightmare occurs~~ Instead, integers form a ring, and is a module over scalar of integers.
