Answer 1

Ответ:

================================

1. - 7 - 4 + 12 - 8 + 9 =  21 - 19 = 2

2. + 5 - 9 - 6 + 4 - 11 =  9 - 26 = - 17

3. - 3 - 8 + 15 - 8 - 2 =  15 - 21 = - 6

4. + 13 - 7 - 5 + 3 - 7 =  16 - 19 = - 3

5. - 11 + 6 - 9 + 5 - 2 =  11 - 22 = - 11

6. + 8 - 12 + 3 + 8 - 9 =  19 - 21 = - 2

7. - 9 + 11 - 7 - 8 + 5 =  16 - 24 = - 8

8. + 2 - 8 - 6 - 3 + 12 =  14 - 17 = - 3

9. + 2 - 3 - 5 + 7 + 8 =  17 - 8 = 9

10. + 17 - 9 - 11 + 5 - 9 = 22 - 29 = - 7

Answer 2

Let's solve these arithmetic expressions step by step:

1. -7 - 4 + 12 - 8 + 9 = -7 - 4 + 12 - 8 + 9 = -7 - 4 + 12 - 8 + 9 = 2

2. +5 - 9 - 6 + 4 - 11 = 5 - 9 - 6 + 4 - 11 = -17

3. -3 - 8 + 15 - 8 - 2 = -3 - 8 + 15 - 8 - 2 = -6

4. +13 - 7 - 5 + 3 - 7 = 13 - 7 - 5 + 3 - 7 = -3

5. -11 + 6 - 9 + 5 - 2 = -11 + 6 - 9 + 5 - 2 = -11 - 9 - 2 = -22

6. +8 - 12 + 3 + 8 - 9 = 8 - 12 + 3 + 8 - 9 = -2

7. -9 + 11 - 7 - 8 + 5 = -9 + 11 - 7 - 8 + 5 = -8

8. +2 - 8 - 6 - 3 + 12 = 2 - 8 - 6 - 3 + 12 = -3

9. +2 - 3 - 5 + 7 + 8 = 2 - 3 - 5 + 7 + 8 = 9

10. +17 - 9 - 11 + 5 - 9 = 17 - 9 - 11 + 5 - 9 = -7

So, the results are:

1. 2
2. -17
3. -6
4. -3
5. -22
6. -2
7. -8
8. -3
9. 9
10. -7
