Comments I've submitted:
PRI#26: It is my understanding that Ethiopic numerals do not use a
Most sources describing Ethiopic script will list the characters
representing tens, 100 and 10000. The existence of these characters,
which are not combinations made from sequences of digits for 0 - 9,
already indicates that this is not a decimal-radix system.
Traditionally, each syllabic character has a numeric value associated.
This is described on page 8 of
http://www.intelligirldesign.com/paper_gabriella.pdf, which shows Arabic
decimal values, and
which shows traditional Ethiopic numerals. By comparison of these two
documents, one can get an idea of how the numbers work.
The following are some other useful discussions of Ethiopic numbering:
The last of these proposes the addition of a digit 0 in order to allow
decimal-radix numbers in Ethiopic. I have no idea whether this has
caught on at all or not, but it is not the traditional system.
