Frequently Asked Questions
What is a cardinal number?
A cardinal number expresses a quantity: one, two, three, forty-two, one thousand. These are the everyday counting numbers you use when you say "I have three apples" or "the population is eight billion". Cardinal numbers answer the question "how many?".
What is an ordinal number?
An ordinal number expresses position or rank in a sequence: first, second, third, forty-second, one thousandth. Ordinal numbers answer the question "which one in order?" and are used in dates (the 21st of March), race results (she finished third), and numbered lists.
