Bonjour,

A = 100 - 43 - 7,20 x 4 + 7,50 : 3

A = 100 - 43 - 28,80 + 2,50

A = 100  + 2,50 - (43 + 28,80)

A = 102,50 - 71,80

A = 30.70

B = 100 - (43 - (7,20 x 4) + (7,50 : 3))

B = 100 - (43 - 28,80 + 2,50)

B = 100 - (43 + 2,50 - 28,80)

B = 100 - (45,50 - 28,80)

B = 100 - 16,70

B = 83,30

C = ((100 - 43) - (7,20 x 4 + 7,50)) : 3

C = (57 - (28,80 + 7,50)) : 3

C = (57 - 36,30) : 3

C = 20,70 : 3

C = 6,90

D = (100 - 43) - (7,20 x 4) + (7,50 : 3)

D = 57 - 28,80 + 2,50

D = 57 + 2,50 - 28,80

D = 59,50 - 28,80

D = 30,70

E = ((100 - 43) - 7,20 x 4 + 7,50) : 3

E = (57 - 28,80 + 7,50) : 3

E = (57 + 7,50 - 28,80) : 3

E = (64,50 - 28,80) : 3

E = (64,50 - 28,80) : 3

E = 35,70 : 3

E = 11,9
