Is it a palindrome?​
If yes, stop or else repeat the above steps to get a palindrome number.​
The number is _____.
( 2 marks )

Solution:
If we turn 6 back to front, we get 6 (0.5 marks)
Adding both of the numbers gives us 6+6 = 12 (0.5 marks)
Is it a palindrome?​ No (0.5 marks)
So, we need to repeat the above steps to get a palindrome number.​
If we turn 21 back to front​, we get 12 (0.5 marks)
Adding both of them gives us 12+21 = 33 (0.5 marks)
As this is a palindrome number we need to stop the steps.
The number is 33. (0.5 marks)
