  • "Palindrome noun. a word, number or sentence reading the same backward as forward: Eg; 'Rotator', 'Madam, I'm Adam' or 'Poor Dan is in a droop'. From the Greek palindromos meaning 'running back again'."

  • "None of the answers you had were correct! 18 is not a palindrome as it reads as 81 backwards, and the same goes for the other numbers. 101, 242, 555 are examples of palindorome numbers."
