How many nines are between 1 and 1000?

To find how many times the digit '9' appears between 1 and 1000, we can count the occurrences in each digit place (hundreds, tens, and units). In the range from 1 to 999, '9' appears 300 times: 100 times in the units place (from 9, 19, ..., 999), 100 times in the tens place (from 90 to 99, 190 to 199, ..., 990 to 999), and 100 times in the hundreds place (only 900 to 999). Including 1000, which does not contain a '9', the total remains 300.
