The first three of these are very similar to our modern numerals, except that the 2 and 3 have been turned sideways during their migrations. The numeral for 4 has been given a smaller turn, and a stroke added.

−Kharosthi numerals exist for 5–9, but these are not of the visual type. It was also possible to write numbers in Kharosthi in something like the manner of Roman numerals, so that 2 would be 𐩀𐩀. However, Kharosthi ~~indicates a custom of counting on four fingers but not the thumb, so it ~~uses a numeral for 4 rather than 5 as in Roman numerals. The Kharosthi numeral for 4 is very similar to X, so 7 in Kharosthi can be approximated in ASCII (right-to-left, again) )))X.

Naturally, we can teach a Turtle how to write this second form of Kharosthi numerals.

−Here are many of the visual numerals that have made it into Unicode as characters, first as ~~a graphic~~, so that you can see them even if you do not have all of the fonts needed to display them. Then I have provided them as text so that you can test which fonts you lack.
