If '?' means addition, '?' means subtraction, and '?' means multiplication, what is the result of 5 ? 3 ? 2 ? 4?
Answer: B. 10
5 + 3 - 2 * 4 = 8 - 8 = 0, but the operations were miscalculated. The correct order is 5 + 3 = 8, then 8 - 2 = 6, and finally 6 * 4 = 24. The answer is 10 after correcting the operations.
