Palindromes
A palindrome is a number or word that is the same backwards and forwards.
Here are some examples: 55, 121, 24342, navan, mam etc.
You can make some numbers into palindromes if you add them to their opposite. 

Onestep palindromes. 
10 is a one step palindrome because 10 + 01 = 11 and 11 is a palindrome 
Twostep palindromes. 
19 is a two step palindrome
because it takes two steps or two addition sums to make it a
palindrome.
Step 1. 19 + 91 = 110 Step 2. 110 + 011 = 121 and 121 is a palindrome. 
Look at our 0  99 chart below.
We worked in groups of four to find out how many steps it takes to turn the numbers into palindromes.
