well, i think if you use this you can find out. A = 1-9 ,B = 0-9 , C = 0-9 , D = 0-9 , E = 0-9 for 2digit numbers = A A for 3 digit numbers = A B A for 4 digit numbers = A B B A and so on till you get to for 8 digit numbers = A B C D D C B A for 9 digit numbers = A B C D E D C B A and last for 10 digit number = A B C D E E D C B A this should work...

How many 3-digit palindromic numbers are there?
To be a 3 digit palindromic number, it must be of the form aba.I assume that a 3 digit number must be at least 100 (so that 020 for example does not count as a 3 digit number):a can be any of the nine digits 1-9;for each of these b can be any of the ten digits 0-9Thus there are 9 x 10 = 90 three digit palindromic numbers.

How many palindromic numbers are there between 1000 and 1100?
If you think about the digits, you can rewrite them as ABBA, with A being one digit and B being another: A can be 1-9 and B can be 0-9. Since A has to be 1, B can be 0-9, leaving 10 palindromic numbers.

Are there 90 palindromic 4 digit numbers between 1000 and 10000?
1001 - 1991, etc = 10, x (2,3,4,5,6,7,8,9) 8 = 80
How many palindrome numbers are there between 10000 to 20000?
100. Palindromic numbers for the range 10000 to 20000 are 5 digits numbers of the form abcba. The first digit ('a') must be '1'. There are 10 possible digits for 'b' (0-9) and for each of these 10 possible digits for 'c' Thus there are 1 x 10 x 10 = 100 palindromic numbers between 10000 and 20000.
