Salut j'ai vraiment besoin d'aide Merci en avance au personne qui contribueront !

CONSIGNE:effectuer les calculs suivants en détaillant vos étapes.

A=6×(5-9);
B=(-3-6)×(6-8);
C=-7×(-3+8);
D=(3-7)×(5+12)
E=(+12)-(-3)×(+7)
F=-5×(+3)+7;
G=(-8)-(-4)×(+7);
H=(-7)×(+2)+(-8);
I=5+(9-6);
J=8-6×(-5) ​

Explications étape par étape :

Bonjour,

A=6×(-4)=-24

B=(-9)×(-2)=18

C=(-7)×5=-35

D=(-4)×(17)= - 68

E= 12+3×7= 12+21=33

F= (-5)×3+7= -15 +7= -8

G= -8 +4 ×7 = -8 + 28=20

H= -7 ×2 -8 = -14 -8 = - 22

I= 5+3=8

J= 8+30=38

A = 6 × (5-9)

A = 6 × (-4)

A = -24

B = (-3 - 6) × (6 - 8)

B = 9 × (-2)

B = 18

C = -7 × (-3 + 8)

C = -7 × 6

C = -42

D = (3 - 7) × (5 + 12)

D = (-5) × 17

D = 85

E = 12 - (-3) × 7

E = 12 - 21

E = -9

F = -5 × 3 + 7

F = - 15 + 7

F = -22

G = -8 - (-4) × 7

G = -8 - 28

G = 36

H = -7 × 2 + (-8)

H = -14 + (-8)

H = 6

I = 5 + (9 - 6)

I = 5 + 3

I = 8

J = 8 - 6 × (-5)

J = 8 - 30

J = -22
