For arbitrary elements, u, v and w of V, and arbitrary scalars, a and b in the field F, Existence of the zero vector in V such that v + 0 = v for all v in V (Identity element) Existence of the inverse element -v in V such that v + (−v) = 0 for all v in V (inverse elements) u + (v + w) = (u + v) + w
