prove that set of all integers is not a vector space
You need to specify what set the scalars are in...If the scalar set is \(\mathbb{R}\), then scalar multiplication isn't closed.
Just have to show an integer multiplied by a scalar is not an integer any more. For example, 4 multiplied by 1.2 is 4.8, which is not an integer any more. Therefore, the set of all integers is not a vetor space.
