Hexadecimal

Hexadecimal is the base system using base sixteen. Typically, the sixteen symbols for hexadecimal are represented as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F in order; sometimes, the letters A, B, C, D, E, and/or F are all lowercase instead of all uppercase. As with other base systems, numbers can be efficiently added, subtracted, multiplied, and divided in hexadecimal.

Applications

Hexadecimal is most commonly used in computer science, as it is a human-friendly way to represent numbers (or more general forms of data) that have been stored in binary.
