What does it mean the sum of the digits in each number is 13?
It means all the digits add to make 13. For example: 85 has the digits 8 and 5. 8+5 =13. Or: 274 has the digits 2, 7 and 4. 2+7+4 = 13. Technically, to find the digit root, you would add the digitts again: For example: 1645 has the digits 1,6,4 and 5. 1+6+4+5 = 16 Then: 16 has the digits 1 and 6. 1+6 = 7 So the digit root of 1645 is 7.
