To add two numbers - 

For example - 
   1 1
   5 6 4 7    Step 1 - Start from the right side and make your way towards the       + 3 4 9 2                        left.
----------------   Step 2 - 7 + 2 = 9
   9 1 3 9     Step 3 -  4 + 9 = 13
                   Step 3 - As the sum is a two digit number, take the digit to the  
----------------   left and add it to the next pair of numbers.
                   Step 4 - Continue the same process with the next two pairs.
                   Step 5 - Display the answer as the sum.
