The hexadecimal number system is a base-16 system. This means it uses 16 distinct symbols to represent numbers.
These symbols consist of the digits 0 through 9 and the letters A through F.
Adding the digits and letters together gives the total number of distinct symbols:
$ 10 (\text{digits}) + 6 (\text{letters}) = 16 \text{ distinct symbols} $
Therefore, the hexadecimal number system uses 16 distinct symbols.
