Answers and explanations

Question 1: The correct answer is B) 810. You can rewrite the expression as (567 - 99) + 432 = 468 + 432 = 810.

Question 2: The correct answer is A) 578. First solve the parentheses: 567 + 89 = 656. Then 1234 - 656 = 578.

Question 3: The correct answer is C) 12. 144 ÷ 12 = 12.

Question 4: The correct answer is A) 888. 999 - 888 = 111, then 111 + 777 = 888.

Question 5: The correct answer is C) 9. 9 × 9 = 81.

Question 6: The correct answer is C) 180. 12 × 15 = 180.

Question 7: The correct answer is A) 1122. 456 + 789 = 1245, then 1245 - 123 = 1122.

Question 8: The correct answer is A) 5555. 9999 + 1111 = 11110, then 2222 + 3333 = 5555, so 11110 - 5555 = 5555.

Question 9: The correct answer is C) 8. 72 ÷ 8 = 9.

Question 10: The correct answer is A) (30 ÷ 6). (6 × 5) = 30, (3 × 2) = 6, so 30 ÷ 6 = 5.
