Answer:
-3
Step-by-step explanation:
Order of Operations rules require that we do any work within parentheses first.
Thus, we must begin with (−5)–[ (−7)+(−3)–(−8) ].
Here, we must do the work within square brackets first: [ (−7)+(−3)–(−8) ]. This is equivalent to [ -7 - 3 + 8 ], or [-2].
Doing this reduces the original problem to the following simpler expression:
(-5) - [-2], which simplifies to -5 + 2, or -3. The value of this expresion is -3.
