Ah, I don't understand you. What do you mean roman 'nine'? a phonetic
way of saying things? What bankers use to help prevent forgeries?
Something else?
This is getting deep. It is an embarrassing metamathematical fact that
numbers cannot be defined. At least, mathematicians gave up trying a
century ago.
In mathematics, the essence of counting a set and finding a result n,
is that it establishes a one to one correspondence (or bijection) of
the set with the set of numbers {1, 2, ..., n}.

Our ancestors defined the fingers (or digits) as "the set of numbers."
Modern mathematicians have managed to enhance the definition
quantitatively but not qualitatively.
Not all of them

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
