A l’aide 1 et 2 merci❤️❤️

Réponse:
1. A = (3 x 9) - (9 Ă· 3) = 27 - 3 = 24
B = 2 x (3,5 - 0,7) = 2 x 2,8 = 5,6
C = (2,4 + 4,8 + 1,2) x (4,5 - 2,5) = 8,4 x 2 = 16,8
D = 3 x 2 + 5 x 3 = 6 + 15 = 21
E = 5 + 3 x 12 = 5 + 36 = 41
F = 3 + 3 x 2 + 32 = 3 + 6 + 32 = 41
2. â—Ź 56 Ă· 8 + 8 = 15 â—Ź 56 + 8 - 8 = 56
â—Ź 56 + 8 Ă· 8 = 57 â—Ź (56 + 8) Ă· 8 = 8
â—Ź (56 - 8) Ă· 8 = 6 â—Ź 56 x (8 - 8) = 0
