Bonjour,

A = (-4) + (-3)

A = (-7)

C = (+13) - (-7)

C = (+13) + (+7)

C = (+20)

B = (-5) + (+12)

B = (+7)

E = -8 - 7

E = -8 + (-7)

E = (-15)

D = 4 - (+9)

D = (-5)

F = -5 + 5

F = 0

H = 10 - (+11)

H = -1

G = 3 - (+9)

G = -6

Bonne journée :)

bonjour

A=(-4)+(-3)=-7

B=(-5)+(+12)=+7

C=(+13)-(-7)=+20

D=4-(+9)=-5

E=-8-7=-15

F=-5+5=0

G=3-(+9)=-6

H=10-(+11)=-1
