Réponse :
Bonjour,
Exercice 6
A = (3 – 5) – (6 + 2)
= –2 – 8
= –10
B = (–6 + 4) – (3 + 2)
= –2 – 5
= –7
C = (7 – 2) + (–3 + 4)
= 5 + 1
= 6
D = (–5 + 3) – (1 – 3)
= –2 – (–2)
= –2 + 2
= 0
Exercice 7
A = (2 – 7) + (–3 – 5) – (2 + 3)
= –5 + (–8) – 5
= –5 – 8 – 5
= –18
B = (2 – 3) – (5 – 1)
= –1 – 4
= – 5
C = (–8 + 6) – (–7 + 11)
= –2 – 4
= –6
D = (–8 + 5) – (–3 – 4)
= –3 – (–7)
= –3 + 7
= 4
