Quote: Roman Numerals are a non-positional notation
Roman numbers don't depend for value on their relative distance from the decimal point like ours does: they had different markers for Ten, Fifty, Hundred, and so on (until they needed really big numbers, when they started using bars over the number which multiplied it by 1000).
Quote: incorporate base #5, as well as base #10 They used a kinda composite system , which used both base five (V, L, D) as well as base ten (X, C, M). Division in roman numbers was ... um ... interesting. whi8ch might have been why they used abaci (though we have no idea if they invented it or teh Chinese, they both used very similar devices).
Quote: Romans used a duo-decimal system for fractions I didn't know that!

OriginalGriff wrote: Romans used a duo-decimal system for fractions Hi,
There is some wonderful scholarly work going on by a modern generation of historians who are correcting the optics of the warped eurocentric/western lens prior generations' scholars looked through, and used to frame the interaction between "West and East."
Lisa Jardine (deceased 2015) is one of my favorites; her work "Worldly Goods" is a masterpiece. Stewart Gordon's "There and Back: Twelve of the Great Routes of Human History" is a newer (2018) contribution. My own amateur research in this area is more oriented to intra-Asian trade, and cultural transmission of ideas, art, and culture.
1300 years ago, in (what is now) China, we could have leased Bactrian camels to take our precious silks and luxury crafts across the Silk Road, a journey of 185 days; the Bactrian Camels, carrying a load of 100~200kg. each, could go for three days without water as we crossed the Taklamakan desert, even though we couldn't. For money, we might have used Sasanian silver (ancient Iranian empire: a high-quality mintage widely used).
But, of course, silk itself was a currency all along the Silk Road.
If we survived our journey, we might have come back rich, perhaps laden with Roman gold. More importantly, we might have had stories to tell that induced wonder in all who heard them.

You might say I am actually Dutch, or that the Romans forced their culture upon Europe, but I will not hear it!
Also, the world is flat, unlike Mars which we have observed to be round.
I am also vegetarian and therefore I am ethically superior to you and everything you say will be twisted and turned and taken out of context so all your arguments are invalid.

No, octal would be more natural, since we actually have 8 fingers.Ayt least I do!

I've recently been watching some YouTube videos late at night about the Sumerian Sexagesimal (base 60)[^] system. It's extremely interesting. The Sumerians absolutely knew about zero.. but they did not have a symbol for it. In all of the clay tablets with calculations requiring a zero... there is a blank space where the number zero should be. That makes perfect sense to me... with zero being NULL.

There is some very interesting speculation about west-to-east (from Egypt) cultural transmission of iconography and the mathematical basis for weights and measures in this book on the weights of Burma (now Myanmar):

It's an out-of print book for a specialist, and ridiculously expensive, now. And, frustrating to read because some very grandiose theories are proposed, but sources are not annotated satisfactorily.
