Bonsoir j’ai besoin d’aide en maths pour l’exercice 19

Bonsoir,

a. 17 - 2 x (8 - 4)

= 17 - 2 x 4

= 17 - 8

= 9

b. 45 : 9 x (6 - 2)

= 5 x (6 - 2)

= 5 x 4

= 20

c. (13 - 5) x (4 + 6)

= 8 x 10

= 80

d. (19 - 7 x 2) + 4

= (19 - 14) + 4

= 5 + 4

= 9

e. 15 + (12 - 3 x 4)

= 15 + (12 - 12)

= 15 + 0

= 15

f. (50 - (13 + 1) x 2) - 6

= (50 - (14) x 2) - 6

= (50 - 28) - 6

= 22 - 6

= 16
