Can you prove that any number is expessable in Roman Numerals?
And a double bar is x10^6? I see...Originally Posted by ThePerfectHacker
Well then, all you should need to be able to do is express any number from 1 to 1000. Then using one bar and "non-barred" numerals you will be able to get to 1,000,000. Then with two bars, one bar, and non-barred you can get to 10^9, etc. This isn't a formal proof (obviously) but one should easily be able to generate one from this.

Well... It's the case with Sumerian, Egyptian, Babylonian etc numerals, that you can express any number with their help; The point is, symbolic notation would be too large, to be of any practical use.
But Babyonians rule; They could even denote decimals (in base 60), which makes their ideas on number very modern - or our ideas on number rather old...
