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).
