Answer 1

Ответ:

1. -3+4-8-5+7= -5
2. -11+6-7+8-4= -8
3. -10+2= -8
4. -3-6-7+4-11= -23
5. 5-13-2-6+7= -9
6. -1+7-15+1-16= 6
7. -8+(-10)+20+(-1)+1= 2
8. 5-(-11)-7+(-6)+7+(-2)= 0
9. -5-7 = -12
10. -3x7= -21
11. -2x(-8)= 16
12. 14:(-7)= -2
13. -20:(-10)= 200

Answer 2

Let's solve the equations one by one:

1. -3 + 4 - 8 - 5 + 7 = -5

2. -11 + 6 - 7 + 8 - 4 = -8

   -10 + 2 = -8

3. -3 - 6 - 7 + 4 - 11 = -23

   5 - 13 - 2 - 6 + 7 = -9

   -1 + 7 - 15 + 1 - 16 = -24

4. -8 + (-10) + 20 + (-1) + 1 = 2

   5 - (-11) - 7 + (-6) + 7 + (-2) = 12

5. -5 - 7 = -12

   -3 x 7 = -21

   -2 x (-8) = 16

   14 : (-7) = -2

   -20 : (-10) = 2

Therefore, the solutions are:

1. -5
2. -8, -8
3. -23, -9, -24
4. 2, 12
5. -12, -21, 16, -2, 2
