Subtracting vectors: A − B as A + (−B)

An example figure from the Vector Diagram Generator.

On a grid, vector A 5 squares to the right, then −B 3 squares straight down from its tip, with the dashed resultant A − B — Vector subtraction drawn as addition: A, 5 squares to the right, then −B, 3 squares straight down from A’s tip, the opposite of a B pointing up. The dashed resultant from A’s tail to −B’s tip is labeled A − B.
