A vector area is a set of components, referred to as vectors, that may be added collectively and multiplied by scalars. A set of components is a vector area if it satisfies the next axioms:
- Closure beneath addition: For any two vectors u and v in V, their sum u + v can also be in V.
- Associativity of addition: For any three vectors u, v, and w in V, the next equation holds: (u + v) + w = u + (v + w).
- Commutativity of addition: For any two vectors u and v in V, the next equation holds: u + v = v + u.
- Existence of a zero vector: There exists a singular vector 0 in V such that for any vector u in V, the next equation holds: u + 0 = u.
- Additive inverse: For any vector u in V, there exists a singular vector -u in V such that the next equation holds: u + (-u) = 0.
- Closure beneath scalar multiplication: For any vector u in V and any scalar c, the product cu can also be in V.
- Associativity of scalar multiplication: For any vector u in V and any two scalars c and d, the next equation holds: (cu)d = c(ud).
- Distributivity of scalar multiplication over vector addition: For any vector u and v in V and any scalar c, the next equation holds: c(u + v) = cu + cv.
- Distributivity of scalar multiplication over scalar addition: For any vector u in V and any two scalars c and d, the next equation holds: (c + d)u = cu + du.
