A Correct answer
Explanation

Approximate and solve: 699.989 ≈ 700, 7.05 ≈ 7, so 700 ÷ 7 = 100. Next, 4.998 ≈ 5, 17.96 ≈ 18, so 5 × 18 = 90. Then, 14.05 ≈ 14, 3.99 ≈ 4, so 14 × 4 = 56. Finally: 100 - 90 + 56 - 12 = 10 + 56 - 12 = 66 - 12 = 54. This matches option A exactly. Remember to follow the order of operations: division and multiplication before addition and subtraction.
