When creating a 4-digit number where each digit can be used more than once, each of the four positions (thousands, hundreds, tens, and units) can be filled by any of the 10 digits (0-9). Since the leading digit cannot be zero in a valid 4-digit number, there are 9 options (1-9) for the first digit and 10 options for the remaining three digits. Thus, the total number of 4-digit numbers is calculated as 9 × 10 × 10 × 10, which equals 9,000.
