4*4=16 sum of 1+6 is 7, difference is 5 so 16 is answer
31
the sum of my digits is 6? answer=60
Add the digits together. The sum of the digits of 23 is 5.
The sum of the digits of a number often reveals patterns, such as divisibility rules. For example, a number is divisible by 3 if the sum of its digits is divisible by 3. Additionally, the sum can provide insights into the number's properties, such as whether it is odd or even. Observing the sum of digits can also help identify sequences or trends in larger datasets.
The number is 45. The sum of its digits i.e. 4+5=9 Five times the sum of its digits i.e. 5 times 9 which is 45
A number is divisible by 33 ifthe sum of the digits is 0, 3, 6 or 9;andthe difference between (the sum of the digits in the odd places) and (the sum of the digits in the even places) is 0, 11, 22, 33, ... . This process may require repeating if the original number is very large,
8 is the same as the sum of the digits of its cube, 512.
1 + 1 = 2 The sum of the digits is therefore 2.
