How 342 is written

342 is the sum of its place values, 300 + 40 + 2, and is written three hundred forty-two.

Its ordinal form is three hundred forty-second — only the final element takes the ordinal ending — and on a check the amount line reads "Three hundred forty-two and 00/100", where 00/100 stands for zero cents.

British English inserts "and" before the last part, giving three hundred and forty-two, where American English writes three hundred forty-two without it.

Its Roman numeral CCCXLII uses subtractive notation: XL means 40, written as X before L instead of repeating X.
