Answer 2

1) 6 - 82 = - 76

2) 69 - 41 = 28

3) - 470

4) - 982 - 658 = - 1640

5) 902 - 370 = 532

6) - 4.6 - 8.1 = - 12.7

7) 8- 1.9 = 6.1

8) - 9.4 - 86= - 95.4

9) 9 - 1.1 = 7.9

10) 29.2 - 7.12 = 22.08

Answer 3

Let's solve these arithmetic expressions step by step:

1. 6 + (-82) = -76
2. 2.69 + (-41) - 3 = -41.31
3. -567 + 97 = -470
4. -982 + (-658) = -1640
5. 902 + (-370) = 532
6. -4.6 + (-8.1) = -12.7
7. 17.8 + (-1.9) = 15.9
8. -9.4 + (-86) - 9.9 + (-1.1) = -107.4
9. 10.2 + (-7.12) = 3.08

Please note that in expressions with decimal numbers, I have considered the proper placement of the decimal point.
