Answer 3

Extra info that you probably don't need:

There are vectors with a more physical representation that can be called 'pointers' (they follow the definition above), and there are also vectors which are single rows or single columns from matrices. They have much the same properties, but are harder to give a physical representation to (draw as an arrow).

A vector is anything that satisfies the axioms of a vector space
