bonsoir , j'ai besion un coup de pouce pour un exercice de math s'il vous plait. calculer en détaillant: C=120-8x{10²+(6-11)x(-3+4x5)] D=(5-7)-(-8+5)+(-7-5)-(9-

C = 120 - 8 x {10² + (6-11) x (-3 + 4 x 5)]

C = 120 - 8 x {100 + (-5) x (-3 + 20)]

C = 120 - 8 x {100 + (-5) x 17]

C = 120 - 8 x {100 - 85]

C = 120 - 8 x 15

C = 120 - 120

C = 0

D = (5-7) - (-8+5) + (-7-5) - (9-5)

D = (-2) - (-3) + (-12) - 4

D = -2 + 3 - 12 - 4

D = 1 - 12 - 4

D = -11 - 4

D = -15

Bonsoir

calculer en détaillant:

C=120-8x{10²+(6-11)x(-3+4x5)]

C = 120 - 8(100 - 5 x (-3 + 20))

C = 120 - 8(100 - 5 x 17)

C = 120 - 8(100 - 85)

C = 120 - 8 x 15

C = 120 - 120

C = 0

D=(5-7)-(-8+5)+(-7-5)-(9-5)

D = (-2) - (-3) + (-12) - 4

D = -2 + 3 - 12 - 4

D = 1 - 16

D = -15
