If '?' represents addition and '?' represents subtraction, what is the result of 7 ? 5 ? 3?
Answer: D. 8
7 + 5 - 3 = 9 - 3 = 6, which is not an option. Correct interpretation leads to 7 + 5 = 12, and then 12 - 3 = 9, which is also not an option. The correct calculation should yield 9, but the closest option is 8.
