PALINDROME

Palindrome is a word which reads the same from backward as it is forward.same known examples are : level ,pop,dad,mom, nayan,1001,1991,2002,and so on.
                  There are 9 palindromes of two digit numbers(11-99).90-90 palindromes of three digits and four digitsand 900 palindromes of five digits,
     Some palindromes are expressed as below :  
1.multiples of 9: 09182736455463728190
2.strange equation : 6*7*6 = 252
                             : 2*(123456789+987654321)+2= 2222222222
3.product of  successive number : 16*17= 272
                                                  : 77*78*79 =474474
4.product of palindrome : 22*11=242
                                      :33*11 =363
5.product of palindrome with numerals "1": 11*11=121 ,11*111=1221 ,111*111= 12321, 1111*1111=12344321 , and so on.
    We know that all product with numerals 1 are palindrome.The only one palindrome year was 1991 in last century and 2002 was the palindrome year of this century.
  Strange fact about palindrome : 
                                          pick out any number that was not a palindrome .Add its mirror number.The result will be palindrome,if not again add the mirror number of the sum to get palindrome number.if the result is still not palindrome ,repeat this process and ultimately the result will be a palindrome number.
EXAMPlE: 49+94=143, 143+341 =484
                 : 19+91=110, 110+011= 121
[NOTE: If u want to try it u'll be fresh,it is a SECRET of MATHS]
