$[4, 0]$

To add or subtract vectors, one can only combine components of like position with each other. Thus, we subtract the second component of c from the second component of b, and we subtract the first component of c from the first component of b to obtain: $b=[2, 3]$ and $c=[-2, 3]$ $b-c=[(2-(-2)), (3-3)]=[4, 0]$
