Quote from Murderous Maths: The key to the universe.
One of the most satisfyingly useless bits of maths are perfect numbers. Only one qualification is required to be perfect: you have to equal the sum of your factors.
6 is the first perfect number, having factors of 1, 2, and 3, summing up to 6.
The next perfect number is 28: 1,2,4,7 and 14, total up to 28 again!
28.6, I am perfect. LOL
