How 19 is written
19 is the sum of its place values, 10 + 9, and is written nineteen.
Its ordinal form is nineteenth — only the final element takes the ordinal ending — and on a check the amount line reads "Nineteen and 00/100", where 00/100 stands for zero cents.
The last part is not built from its digits: English names 10 to 19 with single irregular words, so this is nineteen, never ten nine.
Its Roman numeral XIX uses subtractive notation: IX means 9, written as I before X instead of repeating I.
