One way to combine vectors is through addition (or composition). This can be done algebraically or graphically. For example, to add the two vectors U [-3, 1] and V [5, 2], one can add their corresponding components to find the resultant vector R [2, 3]. One also can graph U and V on a set of coordinate axes, completing the parallelogram formed with U and V as adjacent sides, obtaining R as the diagonal from the common vertex of U and V.
