Thank you for the quick responses! What if the balls were arranged into just one roll, and they could only be taken away sequentially, as they appear in the row. If this is the case, is it then impossible to take away infinite balls and end up with infinite left to go? If so, why?

I know that infinity minus infinity is undefined because subtracting infinity from infinity can equal anything you want. But if I want it to equal infinity, what does the proof look like?

Furthermore, how can I translate the mathematical proof into a story using physical objects. Specifically, say I have an infinite number of balls. How can I illustrate that if I take an infinite number of balls from the pile, that there are still an infinite amount of balls left?
