Bonjour,

Exercice 6

A = (3 – 5)(6 + 2)

= –28

= –10

B = (–6 + 4)(3 + 2)

= –25

= –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)

= –14

= – 5

C = (–8 + 6) – (–7 + 11)

= –24

= –6

D = (–8 + 5) – (–3 – 4)

= –3(–7)

= –3 + 7

= 4
