  • Bonjour,

    (-4,5)x(+100+50)
    =(-4,5)x150
    =-(4,5x150)
    =-675

    -500x(50x100)+(-50)
    =-500x(5000)+(-50)
    =-500x5000-50
    =-2500000-50
    =-2 500 050

    Voilà
  • = ( - 4,5 ) x ( + 100 + 50 )
    = - 4,5 x 150
    = - 675

    = - 500 x ( 50 x 100 ) + ( - 50 )
    = - 500 x 5 000 - 50
    = - 2 500 000 - 50
    = - 2 500 050
