Explications étape par étape
Bonjour
Exercice 5 :
Calculer :
A = 3 - 5 + 4 - 6
A = 7 - 11
A = (-4)
B = -1 + 4 - 2 - 3
B = 4 - 6
B = (-2)
C = -18 + 23 + 47 - 12
C = 70 - 30
C = 40
D = -7 + 3 - 20 + 7 + 5
D = 15 - 27
D = (-12)
Exercice 6 :
Calculer
A = 1 - 5 + 3 + 7 - 4
A = 11 - 9
A = 2
B = -10 + 3 + 8 - 4 - 5
B = 11 - 19
B = (-8)
C = -3 + 11 - 17 + 12
C = 23 - 20
C = 3
D = 28 - 19 - 19 + 10 - 28
D = 10 - 38
D = (-28)
