    Why mathemagic is fun

    perfect number consist of:
    a figure (like 6)
    the sum of all figures it can be devided by sums up to the figure itself.
    to take as an example the previously mentioned.
    (1 is incuded)
    6 can be devided by 1 2 and 3 (the number itself does not count)
    1+2+3 = 6

    28 can be devided by 1 2 4 7 14
    1 + 2 + 4 + 7 + 14 = 28

    sofar the perfect numbers

    Phytagoras invented some intersting things as well

    Code:
    13 03 02 16
    08 10 11 05
    12 06 07 09
    01 15 14 04
    At first sight maybe nothing interesting.
    But if you take a closer look you will notice:
    There are 16 different numbers
    All horizontal lines equal 34
    All vertical lines equal 34
    All diagonal lines equal 34
    If you devide the 'square' into squares of 4 numbers, they all equal 34

    This is one of the reasons why mathemagic is more interesting then the 'a^ + b^ = c ^'


    FYI only

    enjoy

    This reminds me of the magic square riddle thing posted by Agent_Steal
    http://www.antionline.com/showthread...r=2#post685055
    I tried writing a program to solve that, but it only solved like half of it, so I had to go through by hand and figure it out. Maybe I'll try again and see if I can make a program that solves it all the way. Interesting post |gridley|, thanks for sharing.
