It turns out that in our homeland, Arabic numerals did not exist at all until the 18th century.
There was a cunning system based on Cyrillic and symbols. There is even a converter program http://info-7.ru/Titlo/Titlo.shtml Darkness, legion, leodr, vran, deck. Sources: http://hbar.phys.msu.ru/gorm/ahist/cyrik.htm also here http://www.pravpiter.ru/zads/n018/ta013.htm.
Especially interesting is that our ancestors for some reason needed such unimaginable numbers as 10 to the power of 48 and next to it 10 to the power of 50. These are klada, ten vrans and darkness of dark, ten decks. For instance, in the Apocalypse: “The number of the horsemen was two hundred million (Ancient Greek δισ-μυριάδες μυριάδων); and I heard the number thereof” (Rev. 9:16). Not only are various kladas and darkness of dark simply huge numbers, but their powers differ only by a couple of orders of magnitude. Interestingly, maybe scientists have figured something out over something simple.
