Aide moi svp pour exercice 2 et 3

Ex 2 :

a) 8 x (10 +6) = 8 x 16 = 128

b) (7 x 9) + (15 x 11) = 63 + 165 = 228

c) 7 + (11 x 4) = 7 + 44 = 51

d) (8 + 5) x (20 + 14) = 13 x 34 = 442

e) 24 - (20/5) = 24 - 4 = 20

f) (24 - 20) / 5 = 4/5 = 0,8

Ex 3 :

27 - 3 x 4

27 - 12

15

(4+3) x (8-5)

7 x 3

21

24 / 6-5

4 -5

-1

24 / (6 - 5)
