Cardinal, Ordinal, and Nominal Numbers Cardinal numbers, known as the “counting numbers,” indicate quantity. Ordinal numbers indicate the order or rank of things in a set (e.g., sixth in line; fourth place). Nominal numbers name or identify something (e.g., a zip code or a player on a team.) They do not show quantity or rank.
