A number is a mathematical object used to count, measure, and label.
The original examples are the natural numbers 1, 2, 3, and so forth.
A notational symbol that represents a number is called a numeral.
In addition to their use in counting and measuring, numerals are often used for:
- Labels (as with telephone numbers)
- Ordering (as with serial numbers)
- Codes (as with ISBNs).
In common usage, the term number may refer to a symbol, a word, or a mathematical abstraction.
