Pouvez-vous m’aider mercii.

bonjour

A = (25 + 8)/3

A = 33/3

A = (3 x 11)/3

A = 11

B = 45/(12 - 3)

B = 45/9

B = (9 x 5)/9

B = 5

C = 16 + 8/2

C = 16 + (4 x 2)/2

C = 16 + 4

C = 20

D = 42/7 - 4,5

D = (6 x 7)/7 - 4,5

D = 6 - 4,5

D = 1,5

E = (52 - 12)/(13 + 7)

E = 40/20

E = (20 x 2)/20

E = 2

F = (2 x 32)/(14 - 6)

F = 64/8

F = (8 x 8)/8

F = 8
