Bonjour

Calculer en respectant les priorités :

E = (7-5) + (2-3) - (-7 + 5-3)

E = 2 - 1 - (- 10 + 5)

E = 1 - (- 5)

E = 1 + 5

E = 6

F= -10 - (5 -3 + 2) + (-13 + 12)

F = - 10 - (7 - 3) - 1

F = - 10 - 4 - 1

F = - 15

G = 12 - (-8 + 4 - 7) - (9 + 3 - 4)

G = 12 - (- 15 + 4) - (12 - 4)

G = 12 + 11 - 8

G = 23 - 8

G = 15

H = 5- [(12 + 5 - 11) - (7 + 1)]

H = 5 - [(17 - 11) - 8]

H = 5 - (17 - 11 - 8)

H = 5 - (17 - 19)

H = 5 - (- 2)

H = 5 + 2

H = 7.
