Answers to Questions

How to calculate a digital root?

Digital root calculation uses recursive reduction that consists in repeating the operation of adding digits until the result has only one digit.

Example: 789 => 7+8+9 = 24 => 2+4 = 6

This principle is often used in numerology to get a number from the numeric information on an individual, for example from a date of birth:
