The same numerals are used in Iran, where they are called Persian.
Apart from a few different shapes, they are the same as Arabic numerals.

Now here is an interesting trivium: Even though Persian and Arabic
are written right to left, numbers are written left to right.
You are all about to jump up and tell me that the order of writing a
decimal positional system is arbitrary, so what I call left to right
might as well be called right to left starting at the high-order
digit. However, that is not correct and I reassert that numbers are
written left to right.  Can anyone guess what my proof is?

Brendan.
