G=-5+(-12)

=-5-12

=-17

H=9+(-13)

=9-13

=-4

J=13+(-13)

=0

I=7,4+(-0,4)

=7,4-0,4

=7

N=6-(-14)

=6+14

=20

=7-20

=-13

Bonsoir :)

Réponses :

G= -5+(-12)

G = -5-12

G= -17

H= 9+(-13)

H = 9-13

H = -4

I= 7,4+(-0,4)

I = 7,4-0,4

I = 7

J = 13+(-13)

J = 13-13

J = 0

N = 6-(-14)

N = 6-14

N = -8

P = 7+(-20)

P = 7-20

P = -13
