Work Step by Step
To add vectors A and B, draw vector a, then from the tip of vector A draw vector B. A new vector drawn from the tail of A to the tip of B is the sum of the two vectors.
To subtract vector B from vector A, start by drawing vector A, then from the tip of A, draw vector B with the same magnitude, but facing the opposite direction. A new vector drawn from the tail of A to the tip of B is the difference of B from A.
