Found this on youtube.  Feel it is interesting enough to share.

- created by middle school students at Harold Kaveolook middle school on Barter Island Kaktovik, Alaska.

- when adopted by schools, resulted in higher math exam scores among students.

Wow. Where were they when I needed them. 😉

Quite interesting. I already knew about the Mayan numerals and can do calculations with them, but Kaktovic notation certainly seems more elegant, both aesthetically and in intuitiveness, and it's adapted to their language. In that regard...

...you'd need to switch your thinking to base 20, like Clint Eastwood had to think in Russian when "borrowing" the Firefox:

Other languages that do things slightly different when it comes to numbers are East Asian ones: digit grouping separators, if adapted to their way of speaking, should go every four digits instead of three. I noticed it via this song:

As for Indo-European languages, I read somewhere long ago a hypothesis about why the words for new and nine in some of them look and sound similar. The proposed idea was that it's due to weaving in prehistoric times: since you can hold eight thread ends separated between one person's fingers at most, the ninth and subsequent ones would need a new hand (someone else helping) to keep them in place.

Salute.
