2007 ➗ (2+0+0+7) − (2 × 0 ×0 × 7) = ?
Correct answer: C. 223
- A. 9
- B. 214
- C. 223
- D. 2007
Explanation
To solve the expression, follow the BODMAS rule: 1. Calculate inside the parentheses first: (2+0+0+7) = 9. 2. Then divide 2007 by 9: 2007 ➗ 9 = 223. 3. The multiplication within the subtraction part is (2×0×0×7) = 0. Subtracting 0 does not change the result, so the final answer is 223. Options A, B, and D result from errors in applying the order of operations or arithmetic mistakes.
