Calculate the digit sum and reduced digit sum of 209
Digit Sum - Add up 3 digits of 209:
Digit Sum → 2 + 0 + 9 = 11 Since our digit sum is greater than 9, we repeat this process to get the reduced digit sum: Our new number to evaluate is 11
Digit Sum - Add up 2 digits of 11:
Digit Sum → 1 + 1 = 2 Since our digit sum is less than or equal to 9, we have our reduced digit sum
Digit Sum → 1 + 1 = 2
What is the Answer?
Digit Sum → 1 + 1 = 2
