Rokbeigalmki's numeral system is based on finger-binary, in which you can
count up to 31 on one hand, and 1023 using both hands at the same time:

0 = .|.... ....|.
1 = .|.... ....|O
2 = .|.... ...O|.
3 = .|.... ...O|O
4 = .|.... ..O.|.
5 = .|.... ..O.|O
10 = .|.... .O.O|.
31 = .|.... OOOO|O
32 = .|...O ....|.
132 = .|.O.. ..O.|.
613 = O|..OO ..O.|O
1023 = O|OOOO OOOO|O

Just think of it as a binary notation where |O| (extended) = 1, and |.|
(curled) = 0.
The finger positions, going from right thumb to left thumb, are:
Right hand:
1
2
4
8
16
Left hand:
32
64
128
256
512

Just be careful not to use the numbers "4", "128", or (God forbid!) "132"
around people who don't know what you're doing... ;-)

The actual decimal Rokbeigalmki numerals based on this look something
like:
0. O
1. |
2. b
3. U
4. F flipped over a horizontal axis
5. U with a crossbar
6. F rotated 90 degrees counterclockwise
7. W
8. d
9. U with two crossbars
