3. A palindrome is a word or phrase that is spelled the same backward and forward, such as "A man, a plan, a canal - Panama!" We can reger to natural numbers as palindromes as well, if the digits read forward are the same as read backward, such as 14641 or 999999. Are all palindrome numbers divisible by 11?7 If so, prove it. If not, describe explicitly which ones are and which ones are not. Solution: Solution goes here
