To find how many times the digit 3 appears between 100 and 600, we can analyze each digit place (hundreds, tens, and units). In the hundreds place, the digit 3 appears in the range 300-399, contributing 100 occurrences. In the tens place, 3 appears in the sequences 130-139, 230-239, 330-339, 430-439, 530-539, totaling 50 occurrences. In the units place, 3 appears in every complete set of 10 (e.g., 103, 113, ..., 593), contributing another 50 occurrences. Adding these together, 3 appears a total of 200 times between 100 and 600.
