Calculate the digit sum of 73
Calculate the reduced digit sum of 73
Add up 2 digits of 73:
Digit Sum → 7 + 3 = 10
Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 10
Add up 2 digits of 10:
Digit Sum → 1 + 0 = 1
Since our digit sum ≤ 9:
we have our reduced digit sum
Final Answer
Digit Sum = 10
Reduced Digit Sum = 1
Reduced Digit Sum = 1
