# Working with whole numbers

Chapter

## Abstract

The number system that we use today has taken thousands of years to develop. The symbols used are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Each symbol is called a **digit**. Our system involves counting in tens. This type of system is called a **denary** system, and 10 is called the **base** of the system. It is possible to use a number other than 10 as the base, see Section 1.6. For example, computer systems use base 2 (the **binary** system) or base 16 (the **hexadecimal** system).
