Calculate the digit sum of 498
Calculate the reduced digit sum of 498
Add up 3 digits of 498:
Digit Sum → 4 + 9 + 8 = 21
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 21
Add up 2 digits of 21:
Digit Sum → 2 + 1 = 3
Since our digit sum ≤ 9:
we have our reduced digit sum
Final Answer
Digit Sum = 21
Reduced Digit Sum = 3
Reduced Digit Sum = 3
