Sagot :
bonjour
A = ( 14 - 5 ) x 2 = 9 x 2 = 18
B = 12 : ( 6 x 2 ) = 12 ; 12 = 1
C = ( 8 - 5 ) x 3 = 3 x 3 = 9
d = 0.5 x ( 38 - 10 ) = 0.5 x 28 = 14
Bonjour
Calculer chaque expression en détaillant les étapes :
A = [14 - (2 + 3)] x 2
A = (14 - 5) x 2
A = 9 x 2
A = 18
B = 12 : [(4 + 2) x 2]
B = 12 : (6 x 2)
B = 12 : 12
B = 1
C = [8 - (7-2)] x 3
C = (8 - 5) x 3
C = 3 x 3
C = 9
D= 0,5 x [38 - (7 + 3)]
D = 0,5 x (38 - 10)
D = 0,5 x 28
D = 14.
