By interchanging + and -, which equation will NOT be correct? I. 16 ÷ 4 + 6 × 2 - 5 = 15 II. 9 + 8 × 3 ÷ 4 - 2 = 5

1. Neither I nor II
2. Both I and II
3. Only II
4. Only I

Correct answer: Only I

Solution

After interchanging + and -, equation I becomes 16 ÷ 4 - 6 × 2 + 5 = 4 - 12 + 5 = -3, so it is incorrect. Equation II becomes 9 - 8 × 3 ÷ 4 + 2 = 9 - 6 + 2 = 5, which is correct.
