Calculate the digit sum of 281
Calculate the reduced digit sum of 281
Add up 3 digits of 281:
Digit Sum → 2 + 8 + 1 = 11
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 11
Add up 2 digits of 11:
Digit Sum → 1 + 1 = 2
Since our digit sum ≤ 9:
we have our reduced digit sum
Final Answer
Digit Sum = 11
Reduced Digit Sum = 2
Reduced Digit Sum = 2
What is the Answer?
Digit Sum = 11
Reduced Digit Sum = 2
Reduced Digit Sum = 2
