cardinal values: how many?

Ordinal values, which order?

,,,

Cardinal values are numbers that indicate how many of something there are (e.g., 1, 2, 3). They answer the question “How many?” and represent quantity.

Ordinal values are numbers that indicate position or order in a sequence (e.g., 1st, 2nd, 3rd). They answer the question “Which in order?” and represent rank rather than quantity.
