Homework Help: A difficult control input question

  1. May 8, 2008 #1

    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??

    Your hyperlink seems to have commas instead of periods. This should be it:


    EDIT: Strange it only works if I copy and paste the URL into the address bar, not when I click the link.
