Exercice 1:
1 - calculer en écrivant les étapes intermédiaires :
A = 6 x 3 + 7 B = 9 14-5 x 12 C = 17- 3 x 4 D = 1+ 50+ 5 x 2
A = 6 x (3 + 7) B = 23-45 C = (3+5) x (9-7)
D = (13-7) - 2 E = 5-[4-(2 + 1)] F = (3 + 5 x 7) + 2 +1

Réponse:
A = 6 × 3 + 7
A = 18 + 7
A = 25
C = 17 - 3 × 4
C = 17 - 12
C = 5
D = 1 + 50 + 5 × 2
D = 51 + 10
D = 61
A = 6 × (3 + 7)
A = 6 × 10
A = 60
B = 23 - 45
B = -22
C = (3+5) × (9-7)
C = 8 × 2
C = 16
D = (13-7) - 2
D = 6 - 2
D = 4
E = 5 - [ 4 - (2+1)]
E = 5 - (4 - 3)
E = 5 - 1
E = 4
F = (3+5×7) + 2 + 1
F = (3+35) + 2 + 1
F = 38 + 2 + 1
F = 41
