Abstract

The digital root of a natural number n is obtained by computing the sum of its digits, then computing the sum of the digits of the resulting number, and so on, till a single digit number is obtained. It is denoted by B ( n ) . In Vedic mathematics, the digital root is known as Beejank; hence our choice of notation, B ( n ) . Note that the digital root of n is itself a natural number.
