Other comments: Bidiya or Bidiyo has a decimal system. Bidiya is spoken by around 14.000 people (probably more, as this number is from a 1993 census) in the Guera region of central Chad. 

Most speakers are bilingual in Chadian Arabic at least to a certain extent. There are five different dialects with some phonological and grammatical differences, but the numeral system is the same for all of them. (The basic numeral vocabulary is the same, too, with some differences in pronunciation due to the dialectal differences.).

A note on orthography: ŋ and ɗ are used like their IPA counterparts, while ƴ represents the palatal implosive ʄ. ba means ''and''; orror is the plural of orro ''ten''. tayaaka is reminiscent of the feminine form of the adjective toyooko ''big'', although the feminine adjective is usually yaaka.

I am not sure about the meaning of tape. ku in tape ku ɗuŋkuleek is a plural relative pronoun, while ɗuŋkuleek is a plural form of a different adjective which also means ''big''. For numbers over 99, many speakers tend to use the Chadian Arabic words instead (e.g. miya instead of orror orro).

For talking about money, they use the same system as Chadian Arabic, referring to ''riyal'' instead of Central African Francs. One riyal equals 5 CFA, so that 500 CFA would be called miya (riyal) or orror orro (riyal), for example. 3000 is tape ku ɗuŋkeleek paɗaŋ.

Other comments: Bidiyo or Bidiya has a decimal system with special constructions for numbers 6 to 9. The borrowed Arabic numbers for hundreds and thousands.
