  1. (-27) × 1011 – 27 ×(-12)+ 27 × (-1)
    = (-27) × 1011 + (- 27) ×(-12)+ (-27) × 1
    = (-27) × (1011 + (-12) + 1)
    = (-27) × 1000
    = -27000
     

  2. Giải đáp:
     
    (-27) x 1011 – 27 x(-12)+ 27 x (-1)=27 x (-1011) – 27 x(-12)+ 27 x (-1)=27 x (-1011+12-1)=27 x (-1000)                                                                                                                                                =-27000
