How 818 is written

818 is the sum of its place values, 800 + 10 + 8, and is written eight hundred eighteen.

Its ordinal form is eight hundred eighteenth — only the final element takes the ordinal ending — and on a check the amount line reads "Eight 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.
