Answer 2

It seems like you have provided a series of mathematical expressions. Let's solve each of them step by step:

1. 19 - 6 + 14 ÷ 6: First, perform the division: 14 ÷ 6 = 2.33 (rounded to 2 decimal places) Then, subtract 6 from 19: 19 - 6 = 13 Finally, add 2.33 to 13: 13 + 2.33 = 15.33

2. 8. 13 + 8 - 9: This expression seems a bit unusual with a space between 8 and 13. Assuming it's multiplication, we can calculate it: 8.13 + 8 - 9 = 17.13 - 9 = 8.13

3. 6 ÷ 32 - 6 ÷ 23: First, perform the divisions: 6 ÷ 32 ≈ 0.1875 (rounded to 4 decimal places) 6 ÷ 23 ≈ 0.2609 (rounded to 4 decimal places) Then, subtract the second result from the first: 0.1875 - 0.2609 ≈ -0.0734 (rounded to 4 decimal places)

4. 27 - 7 - 7.19: Subtract 7 from 27: 27 - 7 = 20 Then, subtract 7.19 from 20: 20 - 7.19 ≈ 12.81 (rounded to 2 decimal places)

5. 9 - (21 - 8): First, calculate the expression inside the parentheses: 21 - 8 = 13 Then, subtract the result from 9: 9 - 13 = -4

6. (40 - 29) ÷ 12: First, calculate the expression inside the parentheses: 40 - 29 = 11 Then, divide the result by 12: 11 ÷ 12 ≈ 0.9167 (rounded to 4 decimal places)

7. 8 ÷ (19 - 3): First, calculate the expression inside the parentheses: 19 - 3 = 16 Then, divide 8 by 16: 8 ÷ 16 = 0.5

So, the results of the provided mathematical expressions are as follows:

1. 15.33
2. 8.13
3. -0.0734
4. 12.81
5. -4
6. 0.9167
7. 0.5
