Question

Let vectors A=(1,0,-3) ,B=(-2,5,1) and C=(3,1,1), how do you calculate A-B?

Answer 1

A - B = (3 , -5 , -4 )

Explanation:

A - B = (1 ,0 , -3 ) - (-2 , 5 , 1 )

To perform this subtraction : add/subtract the x-components of the vectors. Similarly do the same for the y and z components.

hence: A - B = [ (1-(-2)) , (0 - 5 ) , (-3 - 1 )] = (3 , -5 , -4 )
