Calculate the digit sum of 397
Calculate the reduced digit sum of 397
Add up 3 digits of 397:
Digit Sum → 3 + 9 + 7 = 19
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 19
Add up 2 digits of 19:
Digit Sum → 1 + 9 = 10
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 10
Add up 2 digits of 10:
Digit Sum → 1 + 0 = 1
Since our digit sum ≤ 9:
we have our reduced digit sum
Final Answer
Digit Sum = 19
Reduced Digit Sum = 1
Reduced Digit Sum = 1
What is the Answer?
Digit Sum = 19
Reduced Digit Sum = 1
Reduced Digit Sum = 1
