Question

UpStudy AI · Accepted Answer

1. Evaluate the product:
   $$
   (-2)(4) = -8
   $$

2. Evaluate the exponent:
   $$
   (-1)^3 = -1
   $$

3. Substitute the results into the expression:
   $$
   -7 - (-8) - (-1)
   $$

4. Simplify by changing the subtraction of a negative to addition:
   $$
   -7 + 8 + 1
   $$

5. Compute the sum:
   $$
   -7 + 8 = 1 \quad \text{and} \quad 1 + 1 = 2
   $$

Thus, the final answer is:
$$
2
$$
The final answer is 2.
