I knew it had to be
250 'something or others', suspectly Iranian.
Many, many years ago, a nine year old boy educated me, by scratching the numbers 1 to 10 in Arabic into the sand on the southeren shore of the Caspian Sea, at a place called
Babolshar.
That is how I learned to count 1 to 10 in Arabic.
Brings back memories for me!
