What detail do you want? How to add two numbers together?

Solution 1

Either split the number into the various digits using a loop and divide / remainder, or convert it to a string and use a foreach loop on the characters:

while (myInt > 0)
   {
   myDigit = myInt % 10;
   myInt /= 10;
   ... deal with myDigit ...
   }

string myNumber = myInt.ToString();
int index = 0;
foreach (character c in myNumber)
   {
   ... deal with each digit ...
   }
