Answer 1

Respuesta:

1. 20

2. 0

3. -11

4. 31

5. -17

6. 48

7. -52

8. -11

9. 5

10. 4

Explicación paso a paso:

1. + (+15 – 7 + 8 – 2 + 6) = 20

2. – (-5 + 8 – 7 + 12 – 8) = 0

3. + (-8 + 10 – 15 + 8 – 6) = -11

4. – (+26 – 14 – 20 + 8 – 31) = 31

5. + (+1 – 15 + 9 – 10 – 2) = -17

6. – (+20 – 45 + 31 – 55 + 1) = 48

7. + (-30 + 41 + 1 – 61 – 3) = -52

8. – (+9 – 41 + 30 – 36 + 49) = -11

9. + (3 + 8 – 6 ) – (3 – 10 + 7) = 5

10. – (9 – 8 + 3 ) + (-1 +15 – 6) = 4
