Calculate the digit sum of 386

Calculate the reduced digit sum of 386

Add up 3 digits of 386:

Digit Sum → 3 + 8 + 6 = 17

Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 17

Add up 2 digits of 17:

Digit Sum → 1 + 7 = 8

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

Final Answer


Digit Sum = 17
Reduced Digit Sum = 8
