Counting

Counting is how you mathematically know how much of something there is; by knowing incrementally one-by-one, you are counting it.

In order to count, we use the counting numbers. The total, or final count, is the end result of the counting process. For example, counting the number of oranges in a crate may yield the count of 28.

Things which may be counted are countable.

Complicated counting involves combinatorics.
