Calculate the digit sum of 59

Calculate the reduced digit sum of 59

Add up 2 digits of 59:

Digit Sum → 5 + 9 = 14

Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 14

Add up 2 digits of 14:

Digit Sum → 1 + 4 = 5

Since our digit sum ≤ 9:
we have our reduced digit sum

Final Answer


Digit Sum = 14
Reduced Digit Sum = 5
