Hexadecimal is a number base with 16 digits. It's similar to Binary (2 digits) or Octal (8 digits). Oh, and if you're wondering why numbers like A, B, C, D, E, F, 10 and 11 are called "ack", "bel", "coze", "dith", "epp", "fedd" "xen" and "elezen" instead of "A", "B", "C", "D", "E", "F", "ten" and "eleven", it's because those are my base-16 names for them. Also, 9 is different to avoid inflation. 11 isn't different because it is NOT cannibalism (the numbers aren't even sentient). BTW, can you guess why 20 got frozen? ()
