Bonjour,
Calculer en détaillant les étapes.
A = 24: 6:2x [10 - (4 + 4:2)-2]
A = 4 : 2 x (10 - (4 + 2) - 2)
A = 2 x (10 - 6 - 2)
A = 2 x (10 - 8)
A = 2 x 2
A = 4
B = 72-[64-2 x (32-24:2 + 6)] : 2
B = 72 - (64 - 2 x (32 - 12 + 6) : 2
B = 72 - (64 - 2 x 26) : 2
B = 72 - (64 - 52) : 2
B = 72 - 12 : 2
B = 72 - 6
B = 66.
