        Forming Numbers

        We already know how to form 2-digit numbers from the given digits.

        Now, let us learn the formation of 3-digit numbers from the given digits.

        Let us consider the digits 3, 7 and 8.


        With 3 in the hundreds column: 378 and 387                                          Challenge
                                                                                       How       many      3-digit
        With 7 in the hundreds column: 738 and 783                                     numbers  can  we  make


        With 8 in the hundreds column: 837 and 873                                     by the digits 3, 7 and 8?

        Thus, the numbers formed are 378, 387, 738, 783, 837 and 873.


        Here, the smallest number = 378


        The greatest number = 873
