The sum of two vectors is simply [1]

\mathbf{u} + \mathbf{v} = \left( u_1 + v_1 +, \ldots, + u_n + v_n \right)

One property of vector addition is known as the commutative property [2]:

$\mathbf{A} + \mathbf{B} = \mathbf{B} + \mathbf{A}$

Another property of vector addition is known as the associative property [2]:

$\left( \mathbf{A} + \mathbf{B} \right) + \mathbf{C} = \mathbf{B} + \mathbf{A}$
