2) +8+ (-9-2- 3) =
3) (-7 + 8) – (-9-5) =
4) (- 6 + 4) + (-8 - 2) =
5) - 2+1-(-9 + 7) =​

Answer 1

Respuesta:

1) (-2-4) – (-8+2) =

=(−6)−(−6)=  

=0

2) +8+ (-9-2- 3) =

=+8+(−11−3)=

=+8+(−14)=

=−6

3) (-7 + 8) – (-9-5) =

=(1)−(−14)=  

=15

4) (- 6 + 4) + (-8 - 2) =

=(−2)+(−10)=  

=−12

5) - 2+1-(-9 + 7) =

=−1−(−2)=  

=1
