Explanation:

1. 2.3 NON-POSITIONAL NUMBER SYSTEMS
2. 2.3 NON-POSITIONAL NUMBER SYSTEMSA non-positional number system uses a limited number of symbols in which each symbol has a value. However,the position a symbol occupies in the number normally bears no relation to its value-the value of each symbol is fixed.
3. The hexadecimal numeral system, often shortened to "hex", is a numeral system made up of 16 symbols (base 16). The standard numeral system is called decimal (base 10) and uses ten symbols: 0,1,2,3,4,5,6,7,8,9. Hexadecimal uses the decimal numbers and six extra symbols.
