Best Answer

In mathematics and computing, hexadecimal, or hex, is a positional numeral system with a base of 16. It uses sixteen distinct symbols, most often the symbols 0-9to represent values zero to nine, and A, B, C, D, E, F

A numerical subscript (itself written in decimal) can give the base explicitly: 159 10 is decimal 159; 159 16 is hexadecimal 159, which is equal to 345 10.
