Question

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

Answer 1

`(-6,4,3)`

Explanation:

For vector addition, you simply ad corresponding components separately.
And vector subtraction is defined as `A-B=A+(-B)`, where `-B` may be defined as scalar multiplication of every component with `-1`.

So in this case then

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

`=(-6,4,3)`
