A palindrome 2007-12-13
From pradip:
I have discovered that for any n-digit number, when it's terminal digits are reversed,e.g.,1729 & 9721 & the resulting combinations are subtracted, the resulting solution is always a multiple of 9 & when this multiple of 9 is divided by 9, we will always get a palindrome, Example- 1234 & 4231, 4231-1234=2997/9=333., please I am not sure about the above fact, would please help me in confirming my discovery.

A palindrome question 2004-09-28
From Lilly:
12, 21, 13, and 31 are the only double-digit numbers whose squares are the palindromes of the squares of the palindromes of double-digit numbers. I was wondering why it works for these numbers, and if only these numbers work this way.

Will this always yield a palindrome? 1996-08-28
From Andy Golden:
My friend Justin Skywatcher, said that when his children were in 6th grade, they were taught that if you take any number, reverse it and add the two together, a palindrome will result. If not, continue performing the above operations, and a palindrome will eventually result. Will this always yield a palindrome?
