Questions tagged [sum-of-digits]

A sum of digits, or digital sum, is a number created by taking each digit of one or more other numbers and adding them together.

For example, the sum of digits for the number 12,345 would be 15 because:

1 + 2 + 3 + 4 + 5 = 15

The sum of digits for the numbers 12,345 and 67,890 together would be 45 because:

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 0 = 45

Note that a sum of digits will always be an integer.
