Root Explanation
Hexadecimal is formed from "hex" (from Greek "hex", meaning six) and "decem" (from Latin, meaning ten) combined with the suffix "-al" (meaning pertaining to). The word refers to a numeral system that is based on sixteen, which is composed of the digits 0-9 and the letters A-F, representing values ten to fifteen.
Memory Tip
Think of 'six' ('hex') and 'ten' ('decem') to remember that 'hexadecimal' refers to a system that combines these two bases to represent numbers.
