Work out vector subtraction instantly with clear inputs, formula shown and shareable results.
Vectors subtract component by component. The result a − b points from the tip of b to the tip of a, and its magnitude is the distance between those two points.
Vector subtraction
a − b = (a₁ − b₁, a₂ − b₂, a₃ − b₃)
a − b = (4, 4, −2), of magnitude 6.
No. b − a is the same length but points in the opposite direction.
