Number

A number is a way to represent a value. Most numbers are a combination of digits and symbols. There are many types of numbers, such as integers, fractions, and decimal numbers.

3400, - 17, \frac{4}{3}, and 90.835

Numbers are constant, which means that their value never changes, unlike variables. Number sets are used to categorize numbers together with other numbers that have similar properties.
