Answers to Questions

How to calculate the sum of digits in a number?

The only method is to calculate the sum total of all digits, as does dCode.

Example: 123 => 1+2+3 = 6

One should speak of the sum of the digits of a number (the expressions such as the sum of a digit, or the sum of a number are meaningless)

How to calculate a digital root?

The digital root is computed through recursive reduction (repeated sum) that consists in repeating the addition operation until the result has only one digit.

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

What is the difference between a number and a digit?

A number is made of digits, like a word is made of letters.

Example: There are only 10 digits: 0,1,2,3,4,5,6,7,8,9 (in base 10)

Example: There is an infinity of numbers

Numbers can have only one digit such as 1, 2 ou 3 (they are both numbers and digits)
