Homework Help: math

evaluate the following expression if a= -2, h=5 and w= -8
aw^2(w is squared)-hw

I did (-2)(-8)^2-(5)(-8)
(-2)64-(5)(-8)
-128-(5)(-8)
-128-(-40)
-128=40= -88
I believe this is correct but I want to make sure.
Thank you for your help

correct

however, your line
-128=40= -88 makes no sense,
It is probably a typo, since the + and = are only a "shift" away from each other.
