Answers to Questions
How to calculate the sum of digits in a number?
The only method is to count the sum total of all digits, as does dCode.
Example: 123 $ 1+2+3 = 6 $
Pay attention to say 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 $ and $ 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)
