Then the contents of the drawer at time zero is identical to the contents of the drawer at time one, since all of the socks are identical and there are still an infinite number of them in the drawer at both times. But the contents of the drawer at time zero is also identical to the contents of the drawer at time one plus the sock that was taken out, since they are exactly the same material. So we have the equations:

Are you assuming that the arithmetic of infinite cardinals is the same
as that of the finite cardinals?

Infinite numbers that obey all the rules of finite numbers probably
cannot exist.
