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... :rolleyes: - May 2nd 2006, 04:56 AMtopsquarkQuote:

Well, the point remains, why they chose base 60...

Besides the ritual importance, it is a number you can easily chose a half, a third, a quarter, a fifth, a sixth, a tenth, a twelfth etc from.

That must have made commerse easier... :cool:
