adding a negative is the same as subtracting a positive
PEMDAS
parenthasees first
then mulitplication
so parenthaseees
(3.2+-15.6)=3.2-15.6=-12.4
the other parenthasees
4.1-5.3=-1.2
-12.4-6(-1.2)
multiplication
(-) times (-) =(+)
-6 times -1.2=7.2
-12.4+7.2
addition, or subtraction (7.2-12.4)
answer is -5.2
