Answer 1

5189+(1030 - 709) × 120 = 43709
1) 1030 - 709 = 321
2) 321 × 120 = 38520
3) 5189 + 38520 = 43709
7402 - (3103 + 809) ÷ 12 = 7076
1) 3103 + 809 = 3912
2) 3912 ÷ 12 = 326
3) 7402 - 326 = 7076
3000 - ( 2005 - 1800 ÷9×7) = 2395
1) 1800 ÷ 9 = 200
2) 200 × 7 = 1400
3) 2005 - 1400 = 605
4) 3000 - 605 = 2395
