In mathematics and computing, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a, b, c, d, e, f) to represent values ten to fifteen.

|---|---|---|---|
| 1 | = 1 | b | = b |
| 2 | = 2 | c | = c |
| 3 | = 3 | d | = d |
| 4 | = 4 | e | = e |
| 5 | = 5 | f | = f |
| 6 | = 6 | 10 | = g |
| 7 | = 7 | 11 | = h |
| 8 | = 8 | 12 | = i |
| 9 | = 9 | 13 | = j |
| a | = a | 14 | = k |
