Answer
$-33$
Work Step by Step
Recall, in order to solve problems involving order of operations, we use the PEMDAS rule.
First Priority: P - parentheses and other grouping symbols
Second Priority: E - exponents
Third Priority: M/D - Multiplication or division, whichever comes first from the left to the right
Fourth Priority: A/S - Addition or subtraction, whichever comes first from the left to the right
Apply the exponents first to obtain:
$=(-2)(-2)(-2) -2(2)(2)(2)-3(3)
\\=-8- 16 -9$
Subtract to obtain:
$=-24 -9
\\=-33$
