Introduction

Because computers work best working with multiples of 2, computer programmers often find it easier to work with alternate numbering systems that are based on powers of 2. The most used of these systems is hexadecimal, which is based on 16 digits rather than 10. To create 16 digits, programmers use the letters for the digits beyond 9. This creates much confusion, as hexadecimal numbers often appear to be words rather than numbers.
