Number System by Inuit School Kids now in Unicode

[Tom.G]

TL;DR Summary

The “Kaktovik numerals" is a base 5, 10, 20 number system, and it improved the kids mathematical understanding and computational speed.

In the remote Arctic almost 30 years ago, a group of Inuit middle school students and their teacher invented the Western Hemisphere’s first new number system in more than a century. The “Kaktovik numerals,” named after the Alaskan village where they were created, looked utterly different from decimal system numerals and functioned differently, too. But they were uniquely suited for quick, visual arithmetic using the traditional Inuit oral counting system, and they swiftly spread throughout the region. Now, with support from Silicon Valley, they will soon be available on smartphones and computers—creating a bridge for the Kaktovik numerals to cross into the digital realm.

Interesting number system. I was surprised to find that they had a symbol for zero, but read that one of the girls in the class came up with the idea for a symbol from her arms raised above her head.
