Sagot :
Bonjour
E = 23 - 18 = 5
F = -5 + 5 = 0
G = -2 - (-2) = -2 + 2 = 0
H = -2 + (-12) = -14
E = 23 - 18 = 5
F = -5 + 5 = 0
G = -2 - (-2) = -2 + 2 = 0
H = -2 + (-12) = -14
Bonjour,
E=23-(32-14)=23-18=5
F=(-9+4)+(11-6)=-5+5=0
G=(-13+11)-(5-7)=-2-(-2)=-2+2=0
H=-2+(-4+(-8))=-2+(-12)=-14
Voilàà, j'espère que ça t'a aidé !
