    just doing it abstractly but with these signs, you should first go about this problem in a similar matter.

    And whether i is an imaginary number √(-1) , or just a variable like a,b, c and on... `you should expand the parenthesis and add like terms`

    Or, more creative (4-3i)-(-8+i) (12-8-3i)-(-8+i) (12-8-4i+i)-(-8+i) (12-4i-8+i)-(-8+i) (12-4i)+(-8+i)-(-8+i)

    I assume 4+8= 12 and -3-1=-4 But my example (5-7i)-(9-9i) does it different

    Its because it is 5-9=-4 not +

    (5-(-9)) +(-7-1) two negatives turn into a positive--> (5+9) +(-7+1) @14mdaz

    i thought you said it was (5-7i)-(9-9i), so when you expand it all out its 5-7i-9--9i=-4-2i
