    Descending order (greatest to Smallest)

                Example 2. Arrange the numbers in descending order: 8434, 9750, 465, 1265

                Solution.

                Step 1.  Check the number of digits:

                             8434 → 4 digits          9750 → 4 digits           465 → 3 digits         1265 → 4 digits

                          465 is the smallest, so it comes last.

                Step 2. Compare the thousands place:

                             '8'434                   '9'750                    '1'265

                          From 1, 8 and 9:

                          9 is the greatest, 8 is smaller than 9 but greater than 1 and 1 is the smallest.

                          So, the order becomes: 9750, 8434, 1265, 465

                          Note: If the thousands digit is the same, compare the hundreds place:

                          Example: 8434, 8750, 8265

                          From 7, 4 and 2:

                          7 is the greatest, 4 is greater than 2 and 2 is the smallest.

                          So, the descending order is: 8750, 8434, 8265
