If a = -8, b = 3, and c = -2, what is (a + b) × c?
- A. 10
- B. -10
- C. 26
- D. -26
Answer: B. -10
(a + b) × c = (-8 + 3) × (-2) = (-5) × (-2) = 10... Wait: (-5) × (-2) = 10. Recalculating: (-5) × (-2) = 10 is POSITIVE. Check: -8+3=-5, -5×-2=10. Answer should be A. But let me verify the given answer matches the math: if we get 10, answer is A, not B.
