1. Just for Your interest, Neoslavonic teen numbers (11...19) were evolved from this Old (Church) Slavonic scheme:
   number+na+deset, e.g. 15 = pet+na+deset = petnast.
   
   
2. Number jedin (m.), jedna (f.), jedno (n.) is declined as the soft pronoun in singular.
   example: jedin člověk (N), jednego člověka (G), jednemu člověku (D), jednej ženy (G), ...
   
   
3. When added to other numbers, the number 1 has just only one fixed form jedna in all cases.
   example: dvadesetjedna ljudi (N), dvadesetjedna ljudij (G), dvadesetjedna ljudim (D), dvadesetjedna žen (G), ...
   
   
4. Number dva (m.), dvě (f.), dvě (n.) is declined as the hard pronoun in plural.
   example: dva ljudi (N), dvěh ljudij (G), dvěm ljudim (D), dvěh žen (G), ...
   
   
5. Numbers tri and četyri are also declined as the hard pronoun in plural.
   example: tri ljudi (N), trěh ljudij (G), trěm ljudim (D), trěh žen (G), ...
   
   
6. All other numbers ending by the consonant (e.g. -t, -m) are declined as the noun declension pattern kost (a bone) in singular.
   example: pet ljudi (N), peti ljudij (G), peti ljudim (D), peti žen (G), ...
   
   
7. Number nula (zero, nula) is declined as the noun declension pattern žena (a woman) in singular.
   example: nula ljudi (N), nuly ljudij (G), nulie ljudim (D), nuly žen (G), ...
   
   
8. There is an alternative form of number zero: nijedin (m.), nijedna (f.), nijedno (n.).
   example: nijedin člověk (N), nijednego člověka (G), nijednemu člověku (D), nijednej ženy (G), ...
   
   
9. Number sto (hundred) and its derivatives is declined as the noun declension pattern selo (a village) in singular.
   example: sto ljudi (N), sta ljudij (G), stu ljudim (D), sta žen (G), ...
   
   
10. Number tysača (thousand) and its derivatives is declined as the noun declension pattern duša (a soul) in singular.
    example: tysača ljudi (N), tysače ljudij (G), tysači ljudim (D), tysače žen (G), ...
    
    
11. Number milijon (million) and its derivatives is declined as the noun declension pattern grad (a town) in singular.
    example: milijon ljudi (N), milijona ljudij (G), milijonu ljudim (D), milijona žen (G), ...
    
    
12. Composed numbers are written together in decadic triplets separated by spaces, having declined the last numeric element only.
    example: 12 327 = dvanasttysača tristodvadesetsedem (N), dvanast tysača tristodvadesetsedmi (G), ...
    

ordinal numbers

Neoslavonic ordinal numbers behave (and are declined, of course) in the same way as standard pronouns. Composed ordinal numbers have ordinal form of the last numeric element only.

0	nulty	10	desety
1	p'rvy	11	jedninasty
2	vtory	20	dvadesety
3	trety	21	dvadesetyp'rvy
4	četv'rty	22	dvadesetyvtory
5	pety	100	sotny
6	šesty	200	dvěsotny
7	sedmy	1000	tysačny
8	osmi	2000	dvětysačny
9	devety	1^6	milionty

interrogative, demonstrative and indefinite number

These numbers are not inflected because they behave grammatically as adverbs. The corresponding subject is attached to them in genitive plural.

It is possible to create several numerals using prefixes to the interrogative numerals. Learn them from this table. The same prefixes (e.g. t-, ni-, nie-, ...) are used at pronouns and adverbs.

adverb - like		adjective - like
koliko?	how much?, how many?	koliky?	which one? (question on the order)
toliko	as many, as much, this amount	toliky	this (answer to the question on the order)
nikoliko	no, nothing	nikoliky	no (answer to the question on the order)
několiko	some, some number of	několiky	some (answer to the question on the order)

Remember also these two indefinite numerals, please:

mnogo	many, much  (derived from the adjective mnogy = multiple)
malo	a little, few (derived from the adjective maly = small, little)

examples:

Koliko imaješ aut? = How many cars do you have?
Imaju toliko, koliko jest mi trěba. = I have as many I need.
Vidim několiko ljudij. = I can see some number of people.


fractions, set numbers, multiple numbers

1. Multiple numbers are made using multiplicative suffix -krat (times, multiplied by) and behave as adverbs.
   example: dvakrat = two times, desetkrat = ten times.
   
   
2. Pair (doublet) is par in Neoslavonic, declined as the noun grad (town). Corresponding subjects are in genitive plural.
   example: Imaju tri pary obuvij. = I have three pairs of shoes.
   
   
3. All kind of containers or similar concepts are expressed in the same way as pairs. Corresponding subjects are in genitive plural.
   example: Imaješ jedin buket květov. = You have one bouquet of flowers.
   
   
4. One half is polovina declined by the feminine noun pattern žena (woman). Corresponding subjects are in genitive singular.
   example: polovina hlěba = one half of bread.
   
   
5. Other fractions (1/3, 1/4, ...) are made from ordinal numbers by adding suffix -ina and are declined by the feminine noun pattern žena (woman). Corresponding subjects are in genitive singular.
   example: tretina hlěba = one third of bread.
   
   
6. Decimal numbers have točka (decimal point). This word originaly means any point and is declined by the feminine noun pattern žena (woman), but in decimal numbers it has always the same form točka.
   example: 3.14 = tri točka četyrinast.
   
   
7. In written text, we need to write ordinal numbers in the nominative with point and in all other cases with their inflection endings.
   example: 5. = 5th, fifth (m. sg. N), 5-ego = 5th, fifth (m. sg. G), 5-im = 5th, fifth (m. sg. I), ...
