Palendromes!
Do you know what a palendrome is? Describe... List some words that are palendromes. How can numbers become palendromes? Try this...
Problem Description
If any two digit number is reversed and added to itself, and the process repeated long enough, a palindromic number will result. A palindromic number is one that reads the same forward and backward.
Which two-digit number requires the most number of operations before a palindromic sum is reached? And how many steps are required?
As an illustration of the process, take 57: 57+75=132, not palindromic. But the next step, taking 132, reversing it and adding the two gives 132+231=363, which is a palindrome in
two steps!
