 Maybe so. There expression "to remove all of them in their order" is
an informal expression that might refer to something that can be
expressed mathematically but maybe it does not.

You confuse mathematics with formalism. The greatest mathematicians have lived before formalism had been invented. Formalism is only a crutch for those who cannot think without crutches.
If all naturals can be subtracted then this can be done in their order. For enumerating another set the order is even a precondition.
