Numbers are written by arranging digits in a row and each place in the row has a different value. This value depends on the base of the number system. The most common base nowadays is 10:
We often use these short forms for the columns:
To count in different bases, we just group numbers in a different way. For example, for base 2:
|Sixty fours||Thirty twos||Sixteens||Eights||Fours||Twos||Units/Ones|
Zios count in base 3 so their numbers are grouped like this (we shall only look at the first three columns):
Let's work out what a Zio's 111 is in human numbers (base 10):
So, 111 = (1 x 9) + (1 x 3) + 1 = 13.
Zepts count in base 7 so their numbers are grouped like this:
Let's see what a Zept's 111 is in base 10:
So, 111 = (1 x 49) + (1 x 7) + 1 = 57.
To find out which way each type of creature is facing, calculate each number in human counting (base 10).
Remember that the creatures must be seeing numbers which could be a combination of Zios' and Zepts' legs.
