Kuueteistkümnendnumbrid, also known as hexadecimal numbers, are a positional numeral system with a base of 16. This means it uses 16 distinct symbols to represent numbers. Unlike the decimal system (base 10) which uses digits 0-9, the hexadecimal system uses digits 0-9 and the letters A-F to represent values ten through fifteen. Specifically, A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15.

The primary advantage of the hexadecimal system in computing is its ability to represent binary-coded values more compactly and with greater readability for humans. Since 16 is a power of 2 (16 = 2^4), each hexadecimal digit corresponds directly to exactly four binary digits (bits). For example, the binary number 1111 is equal to the decimal number 15, which is represented by the hexadecimal digit F. Similarly, the binary number 1010 is equal to decimal 10, represented by hexadecimal A. This direct mapping makes hexadecimal useful for displaying memory addresses, color codes (like RGB values), and other data representations in computing. Converting between binary and hexadecimal is a straightforward process of grouping binary digits into sets of four.
