Bonjour
Calculer les expressions suivantes en indiquant toutes les étapes :
A = -12-(-4)×(-5-6)
A = - 12 - (- 4) x (- 11)
A = - 12 - 44
A = - 56
B = -4+[24: (-4)]×[-2x(-6)]+(+4)×(-3)
B = - 4 + [- 6 x (12 - 12)]
B = - 4 - 6 x 0
B = - 4
C = 200-[8× (-3)×(-5)]×(-1)
C = 200 - [- 24 x (- 5)] x (- 1)
C = 200 - 120 x (- 1)
C = 200 + 120
C = 320
D = 15-3x (14-21)-5-(-36-2×(-15))
D = 15 - 3 x (- 7) - 5 - (- 36 + 30)
D = 15 + 21 - 5 - (- 6)
D = 15 + 21 - 5 + 6
D = 42 - 5
D = 37.
