bonjour
Merci de mettre ton profil en collège et non lycée
A = 7.2 + 8 .4 - 9.6 + 2.4
A = 18 - 9.6 = 8.4
B = 2.8 - ( 7.4 + 2.1 + 3.4)
B = 2.8 - 12.9
B = - 10.1
C = - 8 ( - 5 ) - ( - 7 ) ( - 6 )
C = 40 - 42 = - 2
D = - 5 + 2 * ( - 4 )
d = - 5 - 8 = - 13
E = - 4 ( - 2) - 0.5 ( - 1 - 3 )
E = 8 - 0.5 * - 4
E = 8 + 2 = 10
