Talbas uses a base 5 system, and only has numbers up to 24. The words for 6 through 9 are derived from bana (5) + the words for 1-4. Multiples of 5 above that are derived from the words for 2-4 + bana. Other numbers are formed from a multiple of five word followed by a digit. Thus the numbers are as follows:
|1 mas||2 te or san||3 poli||4 koni|
|5 bana||6 bammas||7 bande||8 bambol||9 bankon|
|10 teban||11 teban mas||12 teban te||13 teban poli||14 teban koni|
|15 polban||16 polban mas||17 polban te||18 polban poli||19 polban koni|
|20 komban||21 komban mas||22 komban te||23 komban poli||24 komban koni|
Ordinal numbers: regular ordinals are formed with the -i (genitive) suffix on a number. Exceptions are 'ay (first) and sami (second). Other numbers ending in mas or te are still regular (e.g., 11 is teban masi, not teban 'ay).
