Question

1.(- 6) + (-9) – (-10) + (-5)
2. (- 9) + (-11) – (+15) + (+7) – (-8)
3. (12) - (-15) – (-8) - (+13) – (-10)
4. (8 ) - (-12) – (-9) + (-3)- (-7)
5. (- 5) - (-4) – (-7) + (-8) + (-2)

Answer 1

Respuesta:

−6+(−9)−(−10)+(−5)=−10

2×(−9)+(−11)−15+7−(−8)=-29

(12) - (-15) – (-8) - (+13) – (-10)=32

(8)−(−12)−(−9)+(−3)−(−7)=33

(−5)−(−4)−(−7)+(−8)+(−2)=-4
