A = 10 -6 : (-2)
A = 10 + 3
A = 13
B = (2-7) × (- 3 - 1)
B = - 5 x - 4
B = 20
C = 5-8 × (-2) + 15 : (-5)
C = 5 + 16 - 3
C = 18
D = 10 - 8 x(- 6 - 10 : (-2))
D = 10 - 8 x (- 6 + 5)
D = 10 - 8 x - 1
D = 10 + 8
D = 18.

Effectuer les calculs :
A = 10 -6:(-2)
A = 10 + 3
A = 13
B = (2-7) × (- 3 - 1)
B = (-5) x (-4)
B = 20
C = 5-8 × (-2) + 15 : (-5)
C = 5 + 16 - 3
C = 21 - 3
C = 18
D = 10 - 8 x(- 6 - 10 : (-2))
D = 10 - 8 x (-6 + 5)
D = 10 - 8 x (-1)
D = 10 + 8
D = 18
