An unbounded number can be subtracted individually.
As long as it is finite.
However, if all are
subtracted individually, then a last one is subtracted. That cannot
happen.
Whatever do you mean by that? There is no last to inf.many. „All” are
not finite.
But all can be subtracted collectively: |ℕ \ {1, 2, 3, ...}| = 0.
