What is the numeral

Numeral (numeral name) is an independent part of speech answering the questions "how much?" and "which?", and indicating the number and order of objects. Numerals are divided into three categories: quantitative (three, ten, a hundred, a thousand), collective (three, ten, both) and ordinal (third, tenth, last). They can be definitely-quantitative (two, fifteen, eighteen) and an indefinite quantity (much, little, any).

Numerals in the Russian language are inclined only in cases. With the exception of numbers one and two, which like the adjective and change according to the gender and number. For example: one boy, one girl, one creature, one thing. Numbers two and a half are two generic forms – masculine and neuter are inclined equally, while the female differs from them: two desks, two Windows, but two paintings. In the declension of numerals, which stand side by side with the nouns they either run past, or are consistent with them.
