Chinese Vs. Western Numerology
Chinese Astrology dates back, potentially for as much as three thousand years and it the precursor to Western Numerology developed by Pythagoras around 500 B.C. and the Jewish Kaballah which was developed around 1100 A.D.
The various methods of studying your numerology chart involve combining the numbers of your birth date and reducing them by adding them all together and continuing to add numbers until you are left with one number. For instance 2/22/1972 would be 2+2+2+1+9+7+3+2=28 and then 2+8 = 10 and then 1+0 = 1
You can also derive numbers from words by converting the letters so that A=1, B=2, C=3, D=4, etc.... this is the foundation for Jewish Kaballah where they theorists have converted the entire text of the Kaballah into numbers and they study the patterns and repetitions in the massive set of numbers.
The numbers each have articles written about them for reference so you can find your root traits from the numbers in your birth date and your given names. As with Astrology, Numerology recognizes that the numbers only correspond to your fundamental influences, not including upbringing, relationships and environmental factors relating your birth and childhood.

I will be happy to help make sense of all this in a consultation and we will definitely use Numerology as part of our discussion because it is relatively quick to decipher once you get the hang of it and the influences of the numbers can be a factor in looking at your astrology, your tarot and others.
