Calculate the digit sum of 480
Calculate the reduced digit sum of 480
Add up 3 digits of 480:
Digit Sum → 4 + 8 + 0 = 12
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 12
Add up 2 digits of 12:
Digit Sum → 1 + 2 = 3
Since our digit sum ≤ 9:
we have our reduced digit sum
Final Answer
Digit Sum = 12
Reduced Digit Sum = 3
Reduced Digit Sum = 3
