  1. ( -15 ) . 68 + 2 . ( -150 ) + ( -60 ) . 3
    = ( -15 ) . 68 + 2 . ( -15 ) . 10 + ( -15 ) . 4 . 3
    = ( -15 ) . 68 + ( -15 ) . 20 + ( -15 ) . 12
    = ( -15 ) . ( 68 + 12 + 20 )
    = ( -15 ) . 100
    = -1500

  2. Bạn tham khảo !
    (-15) .68 +2 .(-150)+(-60). 3
    =(-15).68+2.(-15).10+(-15).4.3
    =(-15).68+(-15).20+(-15).12
    =(-15).(68+12+20)
    =(-15).100
    =-1500
