The planets of SOS have different levels of proficiency with math.Greld of course being the most skilled, and several of the Moon worlds sharing last place. But all the worlds use the same basic system and thisis quite different than the system we use today.

The numbers of SOS are all in base 8 or Octal. Thus there are no 8 or 9 symbols in their character set. While this system might seem to have a much smaller range than the base 10 system, this octal system allows them to count to very high numbers just using the hands. This means their counting systems are different.

They count 1,2,3,4, on the fingers of their right hand. Then theystick out their right thumb and first finger to represent 5. Then 6,7 withthe rest of their fingers. The first finger of the left hand is then used to represent the first set of eight. This allows them to count to 64 on their fingers, and up to fabulous high numbers using their toes. Some sophisticated mathematicians have very flexible toes to make this easier.
