    if we say 0/0=n which can be proved by timesing the whole equation by 0 to get 0/0 & obviously n can be any No. :. 1=0/0=2 ect. or is there a fundamental rule I've missed here.

    The fundamental rule you've missed is that you can't divide by zero.

    why does mathematics back down from this are then "you can divide by all No.'s except 0" if we confounded this problem perhaps we would achieve greater enlightenment & even unlock the secretes of the universe. perhaps if all numbers are the same then our understanding of matter & energy would have to be overhauled.

    Maybe you ought to look into it and see what amazing things you discover...

    Well, if you allow division by zero you get a lot of faulty proofs that can be made. For example, I could prove that 0=1, 1=2, and any number of strange things.

    We can have a limit however, and say that \displaystyle\lim_{x \to 0^+} \dfrac{1}{x} = \infty

    To divide by something just use the sharing reasoning.

    10 sweets divided by 2 people = 5 sweets each.
    Because you can share 10 sweets between the 2 people.

    10 sweets divided by 4 people = 2.5 sweets each
    Because you can share 10 sweets between the 4 people, even if you don't get a whole number.

    SO on an so forth, until you get to dividing by 0.

    10 / 0 ... (sticking with the analogy of sweets)
    You cannot share the sweets between noone, because there's noone to give the sweets to. Therefore dividing by 0 is not possible.


    Using the example you tried:
    0/0 = n
    Yes, 0 = n x 0
    but that would only work for the 0/0.
    But what about if it was , say 7 / 0 = ?
    then you would get 7 = ? x 0 Which wouldn't work.

    You may then think that you have provided a counter example by saying 0/0 works.
    However, 0/0 doesn't make sense. Why would you try and share (for example) sweets? There are no sweets to share, let alone people to share it between. WHich is why this is not a counter example as it is also an indeterminate..

    Sometimes you can but it really depends on what you're doing. And 0/0 = 1.

    No, you can't.

    No, it doesn't.

    You can divide by zero. Don't listen to the liars. They're just working for the government and they don't want you to realize that we'd have contact with extraterrestrial intelligence.

    Maybe not in pure maths. But when you do physics you get comfortable with these things.

    Yep, you can take 0/0 to be equal to 1 to make results work out 'properly', but the fact remains that 0/0 makes absolutely no mathematical sense (unless you're taking limits).

     0/0 has no meaning. Taking limits on the other hand has plentiful meaning.

    Yeah, in fact apples and oranges are the same thing as well: just empty a basket of each.

    This is a strange thread. I too was puzzled for a bit by the idea of dividing by 0.

    I feel your pain brother.
