Answer:
(8 (-1))
Step-by-step explanation:
Simplify the following:
8 (7 + 4×2 - 4 (11 - 7))
11 - 7 = 4:
8 (7 + 4×2 - 44)
4×2 = 8:
8 (7 + 8 - 4×4)
-4×4 = -16:
8 (7 + 8 + -16)
7 + 8 = 15:
8 (15 - 16)
15 - 16 = -(16 - 15):
8 (-(16 - 15))
| 1 | 6
- | 1 | 5
| 0 | 1:
8 (-1)
8 (-1) = (8 (-1)):
Answer: (8 (-1))
