The Decimal System of zeme

'Zeme Naga has a decimal numeral system. The numerals from eleven to fifty nine are formed without taking any affixes by compounding the basic numerals from 1 to 9 to the numerals 10, 20, 30, 40 and 50. 60, 70, 80 and 90 are purely multiplication of ten with the basic numerals. Although, 'kereu' denote 'ten' in Zeme, it is not used to form multiplicative compound. Instead of it, 'riak' (denotes ten) is generally used along with basic numerals to form lower multiplicative compound. The multiplicative-cum-additive compound numerals are formed from 61 to 69, 71 to 79, 81 to 89 and 91 to 99 by adding 'ze' between the two basic numerals. Zeme Naga is a tonal language, new data with tones are needed. 1. ket 21. əŋkai-ket 2. kəna 22. əŋkai-kəna 3. kət͡ʃum 22. əŋkai-kət͡ʃum 4. mədai 24. əŋkai-mədai 5. meŋeu 25. əŋkai-meŋeu 6. səruk 26. əŋkai-səruk 7. səna 27. əŋkai-səna 8. dəset 28. əŋkai-dəset 9. səkui 29. əŋkai-səkui 10. kereu 30. himreu, 36. himreu-səruk 11. kereu-ket 40. hədai, 48. hədai-dəset 12. kereu-kəna 50. reŋeu, 55. reŋeu-meŋeu 13. kereu-kət͡ʃum 60. riak-səruk, 61. riak-səruk-ze-ket 14. kereu-mədai 70. riak-səna, 75. raik-səna-ze-meŋeu 15. kereu-meŋeu 80. riak-dəset, 87. riak-dəset-ze-səna 16. kereu-səruk 90. riak-səkui, 99. riak-səkui-səkui 17. kereu-səna 100. hai-ket, 200. hai-(kə)na 18. kereu-dəset 300. hai-(kə)t͡ʃum, 400. hai-mədai 19. kereu-səkui 1000. tʃaŋ, 2000. tʃaŋ-(kə)na, 20. əŋkai 3000. tʃaŋ-(kə)t͡ʃum, 9000. tʃaŋ-səkui Source Wikipedia
