aidez moi svp A= 18-6-4 B= 7x9-5x4 C= (3+5)x(7-9) D= 17+7x9-8+4 E= 3+[5-(4-2)] F= (3-1+5)x(9-7) G= [10+3x[9-2)]x4 H= [14-(11-2)]x[(7-3)x0,5]

Bonjour

A= 18-6-4 = 18-10 = 8

B= 7x9-5x4 = 63-20 = 43

C= (3+5)x(7-9) = 8x -2 = -16

D= 17+7x9-8+4 = 17 + 63 -4 = = 76

E= 3+[5-(4-2)] = 3 + (5-(2)) = 3 + 3 =6

F= (3-1+5)x(9-7) = 3 x 2 = 6

G= [10+3x[9-2)]x4 = ( 10 + 3x7) x4 =

(10 + 21) x 4 = 31 x 4 = 124

H= [14-(11-2)]x[(7-3)x0,5]

= (14-9) x (4x0,5)

= 5 x 2

= 10

Bonsoir
