What this means is that Infinity - infinity = infinity - infinity does not always hold! Crazy, huhn?


Eh, that's all right because infinity-infinity is not well-defined.

Hmm isn't it that every infinite moment 10 balls are put in and one taken out. Therefore you can solve this problem with the equation y=10x-x
i.e. y=9x
therefor as x approaches infinity y approaches infinty

Therefor at midnight there will be an infinite number of balls in the urn.

There is no midnight. It never gets there. Dave the lost's link went here, which is the wikipedia link, but this link describes it better (to me, anyway) and shows arguments and counter-arguments.

I, personally, like this argument if we decide the paradox has no effect:

But if we have an infinite number of time intervals, each ball will have been taken out at some time. So it seems that while, at each instant of time, there are more balls in the urn than have been taken out, at midnite there will be no balls inside the urn.


No matter what, the infinite time intervals has an effect. And where on earth did you get that urn? I want one domokun
