What is the Digit Sum Calculator?

The Digit Sum Calculator is a simple yet practical tool designed to calculate the sum of the digits of an integer and its digit root (also known as the digital root).

What is a Digit Sum? How Do You Calculate It?

The digit sum refers to the sum of all the digits in a number. For example, for the number 1234, the digit sum would be:

1 + 2 + 3 + 4 = 10

This calculation is straightforward—just add up all the digits in the number. For example, for the number 567, you add 5, 6, and 7 together, resulting in 5 + 6 + 7 = 18. So, the digit sum of 567 is 18.

What is a Digit Root? How is It Calculated?

The digit root, also known as the digital root, is found by repeatedly summing the digits of a number until a single-digit result is obtained. For example, for the number 9875, the digit root is calculated as follows:

First, calculate the digit sum:

9 + 8 + 7 + 5 = 29

Then, sum the digits of the result, 29:

2 + 9 = 11

Finally, sum the digits of 11:

1 + 1 = 2

Thus, the digit root of 9875 is 2.

How to Use the Digit Sum Calculator?

Using the Digit Sum Calculator is very straightforward. Simply input an integer, and the calculator will automatically compute the digit sum and the digit root. For example:

• Input 456, and the calculator will return a digit sum of 15 and a digit root of 6.
• Input 379, and the calculator will return a digit sum of 19 and a digit root of 1.

Additional Examples

Example 1: Calculate the Digit Sum and Digit Root of 753

Digit Sum: 7 + 5 + 3 = 15

Digit Root: For the number 753, the digit sum is 15. Then sum the digits of 15: 1 + 5 = 6, so the digit root is 6.

Example 2: Calculate the Digit Sum and Digit Root of 2468

Digit Sum: 2 + 4 + 6 + 8 = 20

Digit Root: 2 + 0 = 2

So, the digit sum of 2468 is 20, and the digit root is 2.
