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

$\left(- 6 , 4 , 3\right)$

#### Explanation:

And vector subtraction is defined as $A - B = A + \left(- B\right)$, where $- B$ may be defined as scalar multiplication of every component with $- 1$.
$- A + B - C = \left(- 1 - 2 - 3 , 0 + 5 - 1 , 3 + 1 - 1\right)$
$= \left(- 6 , 4 , 3\right)$
