The Lexicographical system
The digits in order from koja (one) to poju (eleven) are the counting numbers. The next number is the base which is called twod. The two tables below contain these numbers arranged by tubu (three) and kwod (four).
Counting by kwod (four) 
Counting by tubu (three) 



The first letters cycle in threes (k, p, t) and the last letter cycles in four (a, e, u, d). Knowing this we can add modulo twod (twelve, dozen) more easily. For example, to add tubu we have the same first letter and the last letter goes back one in the cycle of four. So kegu (seven) plus tubu (three) begins with "k" and ends with "e" giving "kade". What is the rule for adding kwod?
