In the Russian language are used different cases with numerals. So, if the number 1, 21, 31 and so on, we can use nouns of the Nominative case. If there are words 2, 3 and 4 in the number, then we use the noun of the Genitive case in the singular. And if in the number there are words from 5 to 20 and all the others, you use the noun of the Genitive case in the plural.
