Answer 2

Let's solve this step by step:

1. 350 ÷ 50 - 210 ÷ 70 - 4 = 7 - 3 - 4 = 0

2. 180 ÷ 2 + 7 × 70 - 70 × 7 = 90 + 490 - 490 = 90

3. 720 ÷ 9 + 180 ÷ 20 - 23 = 80 + 9 - 23 = 66

4. 640 ÷ 80 - 120 ÷ 30 + 9 = 8 - 4 + 9 = 13

5. (120 ÷ 2 + 60 × 6) ÷ 60 = (60 + 360) ÷ 60 = 420 ÷ 60 = 7

6. 4 × 80 - 270 ÷ 3 + 13 = 320 - 90 + 13 = 243

7. 90 × 4 + 60 × 4 - 20 × 7 = 360 + 240 - 140 = 460

8. (270 ÷ 3 + 270 ÷ 9) ÷ 30 = (90 + 30) ÷ 30 = 120 ÷ 30 = 4

9. 2 × 60 - 3 × 40 + 60 × 4 = 120 - 120 + 240 = 240

10. 70 × 4 + 70 ÷ 70 + 50 × 7 = 280 + 1 + 350 = 631

11. 810 ÷ 9 + 7 × 50 - 40 × 8 = 90 + 350 - 320 = 120

12. (5 × 70 - 70 × 4) ÷ 10 + 4 = (350 - 280) ÷ 10 + 4 = 70 ÷ 10 + 4 = 7 + 4 = 11

13. 210 ÷ 7 + 120 ÷ 3 + 70 × 3 = 30 + 40 + 210 = 280

14. 400 ÷ 5 + 5 × 40 - 420 ÷ 6 = 80 + 200 - 70 = 210

15. 2 × 30 - 360 ÷ 4 + 30 × 4 = 60 - 90 + 120 = 90

16. 420 ÷ 7 + 560 ÷ 7 + 4 × 80 = 60 + 80 + 320 = 460
