There's the notion of "Greeking" in fonts. Given that people have recently been reminded of this system again, I wonder whether the Unicode fallback BMP font that renders glyphs as boxes with four digits, one in each corner, will start to be called "Cistercianization". I suppose that the fact that it is a slight misnomer for a hexadecimal system will, as it usually does with misnomers, only encourage the adoption of the term. (-:

After reading the page, it doesn’t seem too bad. Each corner represents a digit so you read each symbol one corner at a time. Arithmetic wouldn’t even be that different to learn compared to Arabic numerals since each digit still has a specific place.

You only need to remember 9 permutations (which themselves constitute a pretty logical sequence), the rest is a simple combination of them

4 boxes at 4 corners = 9,999

It seems to use all 4 quadrants around the stave (vertical or horizontal) at least in some forms. Each quadrant can mark the digits 0-9 letting it represent 0-9999. Though 0 isn't called out in the diagrams I'm seeing on the page, the stave by itself should be sufficient to represent that whether the users of it intended it that way or not.

How do you come to that conclusion?

how about adding a second character next ? Then you would count to 100,000,000.

Just like we do with arabic numbers actually, putting them next to each others. With a single of our digits you can only count to 10 !
