How 418 is written
418 is the sum of its place values, 400 + 10 + 8, and is written four hundred eighteen.
Its ordinal form is four hundred eighteenth — only the final element takes the ordinal ending — and on a check the amount line reads "Four hundred eighteen 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 eighteen, never ten eight.
Its Roman numeral CDXVIII uses subtractive notation: CD means 400, written as C before D instead of repeating C.
