    a real number proof question..

    i got a real number called "x"

    prove that if it follows this rule n>x>=0

    for every real and positive "n"

    then "x" must have the value x=0

    ??

    i dont know how to solve it because
    from this expression
    n>x>=0

    "x" must not be equaled to 0

    i cant see the way to solve it

    ??

    Think about this:
    They´re telling you that a positive real number x is smaller than ANY positive real number n. So n "pushes" x to the 0.
    That´s not even close to a proof, but it may help you, since for what I read you were not getting the idea of the proposition...
