Bonsoir vous pouvez m'aider Exercice1 :
Calculer:
A = (3 - 5) - (6 + 2)
B = (-6 + 4) - (3 + 2)
C = (7 - 2) + (- 3 + 4)
D = (- 5 + 3) - (1 – 3).
2.Exercice2 :
Calculer :
A = (3 - 2) - (2 - 7)
B = 3 - (6 - 2) + (- 5 + 2)
C = 4 + 3 - 2 - (3 + 4)
D = (- 2 + 4) - (3 - 7) + 3 - 5 + 1
E = 3 - (2 + 5) - (3 - 7) - 5
F = 1 - 4 + (3 + 5) - (2 + 7) + 2.
