Answer 2

1. Calculation: 7 + 5.31 + 9 + 13.49

To solve this calculation, simply add the given numbers together: 7 + 5.31 + 9 + 13.49 = 34.8

2. Calculation: 8.31 - (4.29 + 3.721)

To solve this calculation, first add the numbers inside the parentheses, then subtract the result from 8.31: 8.31 - (4.29 + 3.721) = 8.31 - 7.011 = 1.299

3. Calculation: 62.7 + 8.31 + 5.79 + 0.07

To solve this calculation, simply add the given numbers together: 62.7 + 8.31 + 5.79 + 0.07 = 77.87

4. Calculation: (8.21 + 9.73) - 0.001

To solve this calculation, first add the numbers inside the parentheses, then subtract 0.001 from the result: (8.21 + 9.73) - 0.001 = 17.94 - 0.001 = 17.939

5. Calculation: 0.7 * 1.3 + 5.1 / 0.17

To solve this calculation, first perform the division, then perform the multiplication, and finally add the results together: 0.7 * 1.3 + 5.1 / 0.17 = 0.91 + 30 = 30.91

6. Calculation: 3.38 - 2.24 / 1.25

To solve this calculation, first perform the division, then subtract the result from 3.38: 3.38 - 2.24 / 1.25 = 3.38 - 1.792 = 1.588

7. Calculation: (3.38 - 2.24) / 1.25

To solve this calculation, first subtract 2.24 from 3.38, then divide the result by 1.25: (3.38 - 2.24) / 1.25 = 1.14 / 1.25 = 0.912

8. Calculation: 31.7 / 63.4 - 23.4 / 11.7

To solve this calculation, first perform the division separately, then subtract the results: 31.7 / 63.4 - 23.4 / 11.7 = 0.5 - 2 = -1.5

9. Calculation: (0.008 - 0.992) / (5 * 0.6 - 1.4)

To solve this calculation, first subtract 0.992 from 0.008, then perform the multiplication and subtraction in the denominator, and finally divide the numerator by the denominator: (0.008 - 0.992) / (5 * 0.6 - 1.4) = -0.984 / (3 - 1.4) = -0.984 / 1.6 = -0.615

10. Calculation: 13.5 * 9.1 * (-3.3) / (-0.00013)

To solve this calculation, first perform the multiplication, then divide the result by -0.00013: 13.5 * 9.1 * (-3.3) / (-0.00013) = -419.355

11. Calculation: 12 * 7.6 - 7

To solve this calculation, first perform the multiplication, then subtract 7 from the result: 12 * 7.6 - 7 = 91.2 - 7 = 84.2

12. Calculation: 3 - 1.5 * 0.8

To solve this calculation, first perform the multiplication, then subtract the result from 3: 3 - 1.5 * 0.8 = 3 - 1.2 = 1.8

13. Calculation: (3.1 - 2.9) * (3.1 + 2.9)

To solve this calculation, first perform the addition and subtraction inside the parentheses, then multiply the results together: (3.1 - 2.9) * (3.1 + 2.9) = 0.2 * 6 = 1.2

14. Calculation: 5.3 * 5.3 - 4.7 * 4.7

To solve this calculation, first perform the multiplications, then subtract the results: 5.3 * 5.3 - 4.7 * 4.7 = 28.09 - 22.09 = 6

15. Calculation: 3 / 1.5 + 5 / 1.25

To solve this calculation, first perform the divisions, then add the results together: 3 / 1.5 + 5 / 1.25 = 2 + 4 = 6

16. Calculation: 0.81 / 0.009 - 6.5 * 2.6

To solve this calculation, first perform the division, then perform the multiplication, and finally subtract the result from the division: 0.81 / 0.009 - 6.5 * 2.6 = 90 - 16.9 = 73.1

17. Calculation: 0.81 / 0.009 + 6.5 * 2.6

To solve this calculation, first perform the division, then perform the multiplication, and finally add the result from the division: 0.81 / 0.009 + 6.5 * 2.6 = 90 + 16.9 = 106.9

18. Calculation: 0.5 * 0.5 - 0.02 / 0.1

To solve this calculation, first perform the multiplication, then perform the division, and finally subtract the result from the multiplication: 0.5 * 0.5 - 0.02 / 0.1 = 0.25 - 0.2 = 0.05

19. Calculation: (0.68 + 2.45) - 2.22 * 0.3

To solve this calculation, first perform the multiplication, then perform the addition and subtraction: (0.68 + 2.45) - 2.22 * 0.3 = 3.13 - 0.666 = 2.464

20. Calculation: (0.425 + 3.575) / 0.5

To solve this calculation, first perform the addition, then perform the division: (0.425 + 3.575) / 0.5 = 4 / 0.5 = 8

I hope this helps! Let me know if you have any further questions.
