    Hex is base 16, handy for older computer systems with 8 bit memory, but a pain in the rear for the rest of us, unless you think of "e" as a number.

    Counting in hex goes...

    0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f,10,11,12,13,14,15,16,17,18,19,1a,1b,1c,1d,1e,1f,20,21, etc etc up to ff which is 128

    One place you still see hex is in defining colors, especially in HTML. A color can be defined by how much red, green and blue are in it, and these are represented as a series of three 2-digit hex numbers. White (no color) is 000000 (00 red, 00 green, and 00 blue) whereas black is ffffff. So, you might say Roses are ff0000, Violets are 0000ff, :D

    And for us computer geeks hex is a lot handier for defining magic values. Here are a few examples. :D
    0xC0FFEE
    0xDEADBEEF
    0xF00D
