How 29 is written
29 is the sum of its place values, 20 + 9, and is written twenty-nine.
Its ordinal form is twenty-ninth — only the final element takes the ordinal ending — and on a check the amount line reads "Twenty-nine and 00/100", where 00/100 stands for zero cents.
The hyphen in twenty-nine is required: English hyphenates every compound number from twenty-one to ninety-nine.
Its Roman numeral XXIX uses subtractive notation: IX means 9, written as I before X instead of repeating I.
