               Therefore, the answer is 33,948.






                  Example 3



              42538    ×    = 39
              The answer can be obtained through a horizontal arrangement

              method as follows:

             1.  Multiply 42538 by 9 ones:         42538   ×= 9  382842.

             2.  Multiply 42538 by 3 tens:  42538          ×    = 30  1276140.

             3.  Add the results from Steps 1 and 2:
                            + 382842     = 1276140   1658982.

              Therefore, 42538      ×     = 39  1,658,982.
