              Forming greAtest And smAllest numbers

              Aman is making number cards for a maths activity.
              Aman: Papa, I learned about 5-digit and 6-digit numbers. Now,  0 1                                2

              tell me  how to  form the greatest and  the  smallest numbers                     zero   one      two
              using given digits.

              Father: We  can form  many numbers using  the given digits                         3 4 5
              either  by repetition  of  digits  or  without  repetition  of  digits.          three    four    five

              But, to form the greatest or the smallest number, the digits must be in a certain order.
              Without repetition of digits


              Let us form the greatest and the smallest number using the digits 6, 5, 0, 3 and 1.
              greatest  Number: To  form  the greatest number, write the                     tth th H        T    O
              given digits in descending order.                                                6    5    3   1    0

              Thus,  the  greatest number  formed with  the  given digits  is              Greatest           Smallest

              65,310.                                                                        digit              digit
