May be I should reframe the question.
How do you prove there isn't a system of numbers to base N where it
doesn't work?
Thanks,
Robert

There's a reasonably good discussion of this here:

I probably should know this...
So when you rearrange the digits of a number (>9) and take the difference, it
is divisible by nine. A result that sometimes points to accounting errors. If
the numbers are not base 10 the result is divisible by (base-1).
What is the associated theorem for this?
Thanks
