Hexadecimal system

The hexadecimal system is a base-16 numbering system used in mathematics and computer science. It employs sixteen symbols: 0-9 to represent values zero to nine, and A-F to represent ten to fifteen. Hexadecimal is often used to simplify binary code because each hex digit corresponds to four binary digits (bits), making it easier to read and work with large binary numbers. For example, the binary sequence 1010 equals A in hexadecimal. This system efficiently expresses memory addresses, color codes in digital graphics, and other technical applications.
