Calculate the digit sum of 463

Calculate the reduced digit sum of 463

Add up 3 digits of 463:

Digit Sum → 4 + 6 + 3 = 13

Since our digit sum > 9:
repeat this process to get the reduced digit sum:
Our new number to evaluate is 13

Add up 2 digits of 13:

Digit Sum → 1 + 3 = 4

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

Final Answer


Digit Sum = 13
Reduced Digit Sum = 4
