Question

the problem i am having trouble with is...

9 x 3 + 2 x -2 (3--2)

Answer 1

Ok, so first off let's get rid of that nasty double-negative.

Subtracting a negative is the same as adding. So 3 - -2 is the same as 3 + 2.

Given that, can you figure out the rest?

Answer 2

9*3+2*-2(3--2) = (9*3)+2{-2(3--2)}
first, 9*3=27 , and 3--2=3-(-2)=3+2=5
so, 9*3+2*-2(3--2) =27+2*(-2)*5=27+(-20)=7
