I just came across this thread about the base-20 system of the Inuit people and the numerals invented for it in the 1990s: https://mathstodon.xyz/@johncarlosbaez/110215432175491555 This makes simple calculations just beautiful. Hraban

Hans, genial. Once you told to me “hoe krijg je het voor elkaar…”. Now I tell you, how do you get this done… the mail has not even had the time to “cool” down and you post this. I am astonished. Kind regards Willi

Thank you very much! I want to use this for paginations ;)) (Sorry for somewhat erratical response behavior – I’m quite busy preparing for the book fair in Leipzig…) Hraban

Hi! dit is really interesting, I just spent two hours reading different sources. And yes, the SIL GentiumKatovik made the wikipedia show everything nicely! Thanks Hraban Willi

Hi everybody, because I am not a mathematician, I looked on the internet for more explanations for the Katovik numerals. I found on YouTube films, worthwhile to enjoy: https://www.youtube.com/watch?v=fIZB4bRwxqI&ab_channel=Dave%27sMathVideos https://www.youtube.com/watch?v=ObRFHiU_r9I&ab_channel=TheFerret Willi

Hi Willi, What fun! I think I found a couple math items to correct. 1) The second line of the tables at the top of page 2 should be: 1000' 100, 10, 1; 8000, 400, 20, 1 2) For the year conversion: 2023 = 5x20^2 + 1x20 + 3. (Your 0 should be my 1). This will give a three digit Kaktovik numeral. You have 4 digit Kaktovik numerals for 2023, with both a 0 and a 1. Gavin
