I still maintain to this day that the original usable numbers were 2, 3, and 7.

All that 5 and 6 and 9 crap is useless and those letter were and could be done with normal latin letters:

5 already has kh, 6 already has t, 9 already has d, don't know what people used for غ but you can write it with gh
