Calculate the digit sum of 454
Calculate the reduced digit sum of 454
Add up 3 digits of 454:
Digit Sum → 4 + 5 + 4 = 13
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 13
Add up 2 digits of 13:
Digit Sum → 1 + 3 = 4
Since our digit sum ≤ 9:
we have our reduced digit sum
Final Answer
Digit Sum = 13
Reduced Digit Sum = 4
Reduced Digit Sum = 4
