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.

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.
A palindromic number is a number that remains the same when its digits are reversed. Between 1000 and 2000, the possible palindromic numbers have the form "ABBA" where A and B are digits from 1 to 9. There are 9 options for A (1-9) and 10 options for B (0-9), but we exclude the case where A is 0. Therefore, there are 9 * 10 = 90 palindromic numbers between 1000 and 2000.
There are 9 palindromic numbers between 0 and 100: 11, 22, 33, 44, 55, 66, 77, 88 and 99.

The answer to this is .... all the numbers between 999 and 10000
40. Excluding numbers starting with 0.
20 number
0, 8, and possibly 1 depending on how you write it. Anything with only these numbers in a palindromic form (18081) is symmetrical too.
