I like reading about pre-decimal number handling in Europe. This text kind of made me wish for some historical drama movie going all in on doing that tired "genius concentration flow breakthrough" trope (it's always the same sequence of excessive cross fades) with expert handling of the counting board the text describes. And particularly into illustrating how noting down the results in Roman numerals would effectively be like the duality of working in RAM and disk persistence we know from computers. And that's the point were I suddenly realize that they didn't even talk in the same numeral system as we do, probably a wild mix of terms like dozens or score and so on for countables, Latin for years and who knows what more. And, to make things even more weird, spoken Latin, as opposed to their written numerals, seems to be refreshingly decimal except for those crazy duode- and unde- anomalies? From this perspective, it seems almost impossibly unlikely that they kept non-decimal systems around for so long.
