How is a digital root used?
Using Digital Roots is to Check Addition and Multiplication Problems. To check an addition problem, add the digital roots of the addends. Then, check to see if the digital root of that sum is the same as the digital root of the actual sum of the addends.
How do I get the digital root of 5?
A shortcut to finding digital root: Its digital root is 5 because 2 + 7 + 5 + 1 + 8 = 23 and 2 + 3 = 5. Now, the digital sum of 27518 can also be calculated by simply grouping (2 + 7) + 5 + (1 + 8), where the un-grouped value 5 is the digital root (since 2 + 7 = 9 and 1 + 8 = 9 are eliminated from the calculation).
What is the digital root of 46?
