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

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).
