Every number will have only 3 digits. In the ones place, there are 5 choices. For every choice of digit made in the ones place, there are 8 possible choices for the hundreds place (you can choose from 1-9, omitting whatever is used in the ones place), and there are 8 possible choices for the tens place (you can choose from 0-9, omitting whatever has already been used elsewhere).
So there are

So there are
Number 1: (-1+2i)+(6-9i)
Number 2: (3-3i)-(4+7i)
Number 3: (-5+2i)+(-2+8i)
