quelqu'un pourrait m'aider s'il vous plaît car j'arrive pas A=(-3) - ((+8) -(-9))+(-3) B =[(-3) - (+5)) +((-1)+(-7)) C=(-7) -((-3) + (+7)) +(-2) D=(+7) + ((+1)

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

=-3-(8+9)-3

=3-(17)-3

=-3-17-3

=-20-3

=-23

B =[(-3) - (+5)) +((-1)+(-7))

=-3-5-1-7

=-8-1-7

=-9-7

=-16

C=(-7) -((-3) + (+7)) +(-2)

=-7-(+4)-2

=-7-4-2

=-11-2

=-13

D=(+7) + ((+1) – (-9)) + (-10)

=7+1+9-10

=8+9-10

=17-10

=7

E=(-7) - (+3)+(-10) -(-9)

=-7-3-10+9

=-10-10+9

=-20+9

=-11

F = (+6) + (-4) - (-1)+(-4)​

=6-4+1-4

=2+1-4

=3-4

=-1

Réponse:

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

(-3)-(+8+9)+(-3)

-3-17-3

-23

b=((-3)-(+5))+((-1)+(-7))

(-3-5)+(-1-7)

(-8)+(-8)

-16

c=(-7)-((-3)+(+7))+(-2)

(-7)-(-3+7)+(-2)

-7-4-2

-13

d=(+7)+((+1)-(-9))+(-10)

(+7)+(+1+9)+(-10)

+7+10-10

7

e=(-7)-(+3)+(-10)-(-9)

-7-3-10+9

-20+9

-11

f=(+6)+(-4)-(-1)+(-4)

+6-4+1-4

2+(-3)

-1
