For a 3 digit number, the left most or the most significant digit cannot be zero. So it can be 1,2,3,4,5,6,7,8 or 9 which is 9 possibilities. The middle number can be 0,1,2,3,4,5,6,7,8,9 which is 10 possibilties but one of the digits has been chosen already as the first digit, so the possibilities are only 9. The right most number can be 0,1,2,3,4,5,6,7,8,9 which is 10 possibilities but two of the digits have been already used by the left most and the middle digits. That leaves only 8 possibilities. So the total number of three digit numbers that have three distinct digits is 9 x 9 x 8 = 81 x 8 = 648 possibilities

Middle digit filling systems are organizational methods used primarily in records management and filing systems. They involve categorizing and storing documents based on the middle digit of a numerical code, rather than the first or last digit. This approach allows for more efficient retrieval and reduces congestion in filing systems, as it spreads out records more evenly across different categories. It is especially useful in large databases or libraries where records need to be accessed quickly and systematically.
Numbering systems that uses three systems a. is serial numbering, 2. Unit numbering, using number adaptation of this social security, family numbering serial units 2. Alphabetical number is Filing Systems types are combines alphabetical filing system with alphabetical identification with alphabetical filing, watch out for same name in this system. 3. Terminal digit -straight numerical and middle digit filing system- Terminal digit uses 6 numbers for three section example 12-04-00, terminal is 12, secondary digits is 04, primary digits is 00. Straight numbering is medical records are filed in straight chronological order. Middle digit is an alternative to the terminal, is a combination of terminal and middle with 6 digits except the middle digits are m\primary and left digits are secondary and the right are tertiary with a block of 100 example records files in straight numerical order is 55-42-97, follows 55-42-98
when using terminal digits filing method, the 79 is secondary
The filing system that is usually used in the hospital environment is called terminal digit filing. This is where you read from the last number, and then look forward. Most hospitals use this format with the fact that if there is a misplaced file, it can be found immediately.

Terminal digit filing is a filing system used to organize numerical records in numerical order. In this system, the last digit of each record is used as the filing criterion. To convert straight numerical to terminal digit filing, you must first identify the last digit in each numerical record. Then, you must organize the records in numerical order based on the last digit. For example, if the numerical records are 12, 21, 17, and 31, the last digits are 2, 1, 7, and 1, respectively. The records should be organized in numerical order based on the last digit to be 1, 1, 2, 7 (21, 31, 12, 17).
