The Pythagorean method was developed by Pythagoras, a Greek mathematician and a philosopher who was born around 590 BC. He was most widely known for his proposition that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
Like the Chaldean method, Pythagorean numerology analyzes both name and date of birth, and the interaction between the two. The basic vibrations are 1 through 9. The numbers 11 and 22 are considered to be master vibrations and hence not reduced to a single digit.
Pythagoras method is popular especially in the west. There are five primary numbers in Pythagorean method derived from your date of birth and name. They are
