Well-known languages generally have a O(log n) way of expressing the natural number n.
Toki Pona, on the other hand, has words only for “one” (wan), “two” (tu), “five” (luka, which also means “hand”), and “many” (mute), and these words are additive.
For example, thirteen is mute or luka luka tu wan.
Expressing specific numbers greater than twenty in such an O(n) system is uncommon. Below is a Befunge program that translates a number into this notation:
&>:!#@_:4`#v_1-:#v_0"naw">:#,_@
>^#<$:-1$<@>:4+>$0" akul">:#,_v
$5-^>:#,_^#:"tu "<<(c) Lament>>
