How 813 is written
813 is the sum of its place values, 800 + 10 + 3, and is written eight hundred thirteen.
Its ordinal form is eight hundred thirteenth — only the final element takes the ordinal ending — and on a check the amount line reads "Eight hundred thirteen 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 thirteen, never ten three.
