cardinal numbers
How many, specifically
Cardinal numbers are the counting numbers—one, two, three, and so on—used to express quantity rather than order.
They answer "how many?" while ordinal numbers (first, second, third) answer "which one in sequence?" There were seven cardinal sins.
In mathematics, cardinal numbers extend to infinite quantities, measuring the size of sets.
