Answers to Questions (FAQ)

What is a digital root? (Definition)

A numeric root is the sum of the digits of a number repeated until a single digit is obtained.

How to calculate a digital root?

Digital root calculation uses recursive reduction that consists in repeating the operation of summing/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 (from a date of birth, favorite number, etc.)

Example: 25/12/2000 => 2 + 5 + 1 + 2 + 2 + 0 + 0 + 0 = 12 => 1 + 2 = 3

Why calculating a digital root?

In mathematics, the calculation of the numerical root is used when casting out 9s.

In numerology, the number root is used for anything and everything.

How to calculate a digital root for a name?

It is possible to assign a value to a name using the position of letters in the alphabet (see A1Z26 code where A = 1, B = 2, … Z = 26) then make the desired additions and analyze the total.

Example: DCODE = 4,3,15,4,5 and 4+3+15+4+5 = 31 => 3+1 = 4
(variant) DCODE = 4,3,15,4,5 and 4+3+1+5+4+5 = 22 => 2+2 = 4
