Other comments: Kambaata has a decimal system. The numeral tor-dúma '10' is is morphologically complex. It consists of the stem tor- ‘10’ plus the building morpheme for tens, -duma, and could thus literally be translated as ''ten-ty''.  As shown in the above table, the subsequent tens ('20', '30', …, '90') are formed through multiplication. The numbers from 2 to 9 serve as multipliers, -duma as multiplicand. A long vowel is located between multiplier and multiplicand. This vowel is mostly -aa (see, for instance, ont-aa-dúma '50'), in one case -oo (see lam-oo-dúma '20')  The lexeme sadʒdʒ-aa-dúma ‘30’ is slightly irregular: it contains dʒdʒ as a second stem consonant while the basic numeral sás-o ‘3’ has a stem-final s.

Note that the numeral tor-dúma ‘10’ contains an element tor-, the numerals from 11 to 19 are based on another allomorph of ‘10’, namely too-. Whereas the long vowel between the multiplier ‘two’ and the multiplicand ‘ten’ is -oo in lamoo-dúma '20', it is ee for the numbers between 21 and 29; see, for instance, lam-ée-na hezzéetto

‘28’. All other numbers consisting of tens plus units are generated in a regular way

and the long vowel of the tens is retained in the tens plus units; see, for instance, sadʒdʒ-aa-dúma ‘30’ and sadʒdʒ-áa-na ónto ‘35’.

The numbers t’ibbíta ‘100’ and kumíta ‘1000’ are not case and gender-agreeing numeral attributes but feminine nouns. With the younger generation, kumíta is being replaced by the Amharic loan ʃii '1000'. The numeral milooná ‘one million’, a masculine noun, is borrowed from European languages via Amharic. As modifiers of a head noun, the numeral nouns are always encoded in the genitive case.
