What is the point of digit sum?
The digit sum – add the digits of the representation of a number in a given base. For example, considering 84001 in base 10 the digit sum would be 8 + 4 + 0 + 0 + 1 = 13. The digital root – repeatedly apply the digit sum operation to the representation of a number in a given base until the outcome is a single digit.
