• Transum,
•  
• 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'.
• Tony, Cumbernauld
•  
• None of the answers you had were correct! *** is not a palindrome as it reads as *** backwards, and the same goes for the other numbers. 101, 242, 555 are examples of palindorome numbers.
  
  [Transum: Thanks for the comment Tony but I think you have a slight misunderstanding. The answers provided below are the number of palindromic numbers in the range... not the numbers themselves.]
• Emma,
•  
• Those are the answers to the question...ie there are *** numbers less than 10, *** less than 100 etc.
• Charlie, Guernsey
•  
• For 10 its *** and *** for 100, 27 for 1000 and 36 for 10000 so it goes up in 9s.
• Mr, Smith
•  
• Actually for less than 1000 there are *** answers, 101,111,121,131,141,151,161,171,181,191, this pattern occurs eight more times for the 200's, 300's... etc. Add the *** for less than 100 and you will have 9 x (9 + 1) + 18 = ***
  For under 10000 there are 279 ways 9 x (18 + 1) + ***
  The pattern is ***, ***, ***, 279
  for less than 100 000 it would be "9 x (108 + 1) + 279"
  I know explanations are missing but I'll leave you with some of the work.
• Maths Assassin, Mrs Hope's Class
•  
• NEVER ODD OR EVEN is the same backwards.
