Bonjour j’aimerais vraiment vous mettiez sur cet exercice je ne comprends pas merci


B= 5 + 7x2
D= 12-4x3
C= (12-4)x 3
A =(5 + 7)x 2
E= (21 – 18)x (12 - 10) + 1
F= 18 + (12- 2x (13-9)]
G=(4,8 - (2,5 +0,3))x (3 + 3,5)
H =[18+ 2 x(120 - 45)] x1,5
1 =700 - [300 – (300 – 80)]




Solutions : F = 22; G = 13; H = 252; 1= 620

bonsoir

B= 5 + 7x2

B = 5 + 14

B = 19

D= 12-4x3

D = 12 - 12

D = 0

C= (12-4)x 3

C = 8 x 3

C = 24

A =(5 + 7)x 2

A = 12 x 2

A = 24

E= (21 – 18)x (12 - 10) + 1

E = 3 x 2 + 1

E = 6 + 1

E = 7

F= 18 + (12- 2x (13-9)]

F = 18 + (12 - 2 x 4)

F = 18 + 12 - 8

F = 30 - 8

F = 22

G=(4,8 - (2,5 +0,3))x (3 + 3,5)

G = (4,8 - 2,8) x 6,5

G = 2 x 6,5

G = 13

H =[18+ 2 x(120 - 45)] x1,5

H = (18 + 2 x 75) x 1,5

H = (18 + 150) x 1,5

H = 168 x 1,5

H = 252

I =700 - [300 – (300 – 80)]

I = 700 - (300 - 220)

I = 700 - 80

I = 620
