Answer:
-20
Step-by-step explanation:
According to PEMDAS, we need to do the math in the parentheses first.
Applying PEMDAS to the inside of the parentheses, then we have to divide -6 by -1, where we would get 6.
Adding a negative is the same as subtracting, so adding negative 10 is the same as subtracting 10.
Subtracting, we get 6 - 10 = -4 and we're left with:
Multiplying, <u>our final answer is -20.</u>
