Calculate the digit sum of 178
Calculate the reduced digit sum of 178
Add up 3 digits of 178:
Digit Sum → 1 + 7 + 8 = 16
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 16
Add up 2 digits of 16:
Digit Sum → 1 + 6 = 7
Since our digit sum ≤ 9:
we have our reduced digit sum
Final Answer
Digit Sum = 16
Reduced Digit Sum = 7
Reduced Digit Sum = 7
