A difficult control input question

  1. htp://s290,photobucket,com/albums/ll279/transgalactic/?action=view&current=IMG_8838,jpg

    the main problem comes when in one input i need to divide the number by 2
    (subtract a zero from the original input)

    while in other control input i need to multiply by two
    (which meens to add a zero to the original input)

    i dont know how to delete or add an output
    when i have a certain control input

    the number of outputs is constant

    what should i do??
