I have received this as Whatsapp forward from many of my contacts with the title Number Magic. All the squares calculated here are Palindrome Numbers. Palindrome Numbers are the numbers which when read from either left-to-right or right-to-left come out to be the same.

At that time the rest of the world didn’t even know how to count using decimal numbers.
