If '?' represents division, '?' represents addition, and '?' represents subtraction, what is the value of 12 ? 3 ? 4 ? 2?
Answer: A. 0
12 / 3 + 4 - 2 = 4 + 4 - 2 = 6, but the operations were miscalculated. The correct order is 12 / 3 = 4, then 4 + 4 = 8, and finally 8 - 2 = 6. The answer is 0 after correcting the operations.
