12(-8 + -4)
First let us do the calculation of the numbers inside the brackets.
-8 + - 4 = -12 (+ of - is -)
So, 12 ( -12) = - 12 x 12 = - 144

parentheses come first -8 + -4 = -12 (rule of adding integers is same signs add and keep the sign)
12 x -12 = -144 ( rule for multiplying integers is opposite signs make a negative)
