A palindrome reads the same forwards as backwards.
Therefore the first and last digits must be the same, the second and penultimate the same, and so on.
As 1000 & 3000 both have 4 digits, there are two pairs of digits that must be the same: the first and fourth, the second and third.
The first digit (and hence last digit) can only be 1 or 2 - a choice of 2
The second digit (and hence third digit) can be any of 0, 1, 2, ..., 9 - a choice of 10 for each of the choices of the first/last digit.
Thus there are 2 × 10 = 20 palindromes between 1000 and 3000.

To find the number of palindromes between 1000 and 3000, we can break it down by the possible combinations of digits. There are 10 choices for the first digit (1-2), 10 choices for the second digit (0-9), and only 1 choice for the third digit (the same as the first). Therefore, there are 10 * 10 * 1 = 100 palindromes between 1000 and 3000.
Oh, what a delightful question! Let's take a moment to appreciate the beauty of palindromes. Between 1000 and 3000, there are 109 palindromic numbers, each one a little work of art in its symmetry. Keep exploring the wonders of numbers, my friend, and let your creativity flow like a river of paint on a canvas.
