Proving Zp is a Vector Space for Prime p

In summary, the conversation discusses the proof that Zp is a vector space if and only if p is prime. The concept of vector space and its axioms are also mentioned, along with the question of which field the vector space is over. It is clarified that the problem is to show that Zp is a vector space, not a field. It is stated that any field can be a vector space over itself, but it is sufficient to prove that Zp is a field if and only if p is prime.

What does the Z5 under addition and multiplication look like? What are the axioms of vector space?

A vector space over what field? Are you sure the problem is not to show that Zp is a field if and only if p prime?

The exercise doesn't specifies so I think is any field, and yes I'm sure the problem is vector spaces not fields

Any field is a vector space over itself so it is sufficient to show that Zp is a field if and only if p is prime.
