Numerology

Numerology is an interesting little branch that adds up things like the letters in your name and date of birth before giving you an overview and description. It has 11 numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22. You can read the keywords for each number here.

Numerology depends on a strange method of adding called "reduction". In example, if you add up all the numbers in your name and you get 78:
7 + 8 = 15
1 + 5 = 6
Your number is therefor 6!

Numerology is a lot deeper than a bit of weird math, so feel free to research it further if it catches your interest.
