Numerals are divided into cardinal numbers and ordinal numbers.
There are simple, derived and composite cardinal numerals.
The cardinal numerals from 1 to12 as well as 100,1000 and 1,000,000 are simple.
The numerals from 13 to 19 and those indicating tens are derived (derivatives-похідні). The numbers from 13 to 19 are formed by adding the suffix –teen to the corresponding numbers of units.
They have two stresses: on the first syllable and on the suffix. f.E fifteen, nineteen
The cardinal numerals indicating tens are formed by adding the suffix – ty to the corresponding number of units. They have the stress on the first syllable.
The numerals consisting of tens and units are spelt with a hyphen. In the composite numerals denoting numbers greater than 100 the conjunction and is used before the tens ( or before the units if there are no tens).
When the numerals hundred, thousand, million are preceded by another numeral, they turn no plural ending –s. When they are not preceded by other numerals, they turn into nouns. In this case they take the plural ending –s and are following by a noun with the preposition of.
The ordinal numerals with the exception of the first three are formed by adding the suffix –th to the corresponding cardinal numeral.
four –fourth fifteen-fifteenth five – fifth twelve – twelfth eight – eighth nine –ninth sixty - sixtieth
one – first two – second three – third twenty-one –twenty – first three hundred and sixty-four – three hundred and sixty-fourth
