# Thread: Why mathemagic is fun

1. ## 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

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 ^'
