Vector Subtraction

Subtracting a vector is the same as adding its negative.

The difference of the vectors p and q is the sum of p and –q.

p – q = p + (–q)

Example:

Subtract the vector v from the vector u.

Solution:

u – v = u + (–v)

Change the direction of vector v to get the vector –v.

Check: The column vector should represent the vector that was drawn.
