90 of them.
There are 300 occurrences of the digit '1' between the numbers 1 and 1000. This includes the numbers 1-999, where '1' appears in the hundreds, tens, and units places. Additionally, the number 1000 contains one '1', bringing the total to 301.
The digit 9 occurs 271 times between 100 and 1000. It appears in three places: the hundreds, the tens, and the units. In the hundreds place, 9 only appears in the numbers from 900 to 999, contributing 100 occurrences. In the tens and units places, each contributes 90 occurrences (from 190-199 and 90 numbers in the units place across each hundred), resulting in a total of 271 appearances of the digit 9.

Palindromic numbers between 1 and 1000 are numbers that read the same forward and backward. The palindromic numbers in this range include single-digit numbers (1 to 9), two-digit numbers like 11, 22, 33, up to 99, and three-digit numbers such as 101, 111, 121, up to 999. Specifically, the three-digit palindromes follow the pattern ABA, where A and B are digits. In total, there are 199 palindromic numbers between 1 and 1000.
There are 900 three-digit whole numbers between 1 and 1000
In every 100 there are 10 numbers that have a units digit of 2 and 10 with 7, making 2 with 2 or 7. Between 0 and 1000 there are 10 hundreds, making 10 × 20 = 200 such numbers. BUT 2 and 7 are less than 10, so there are two less such numbers, making 200 - 2 = 198 such numbers.

Specify whether you are including the numbers between 0000 and 1000.
There are 199 palindromic numbers between 0 and 1000. These include single-digit numbers (0-9), which total 10, and two-digit numbers (11, 22, ..., 99), which add up to 9. Additionally, there are 90 three-digit palindromic numbers, ranging from 101 to 999, that follow the format aba (where a and b are digits). Thus, the total is 10 (single-digit) + 9 (two-digit) + 90 (three-digit) = 109 palindromic numbers.
