              To read and write the number name, always begin from the highest place, i.e., thousands.

              Step 1:  Read and write the number name of the thousands place digit and add the word
                       ‘thousand’ after it.
              Step 2:  Read and write the number name of the hundreds place digit and add the word
                       ‘hundred’ after it.

              Step 3: Finally, read and write the number name of the digits in the tens and ones places
              together.

              Example: Write the number names of the following.
                   (a)  1947                                         (b)  7806

              Solution:  (a)                                        (b)
                                  Th H t O                                Th H t O

              4-Digit Numbers oN abaCus


              An abacus is a tool used for counting numbers. To represent a 4-digit
              number on abacus, we use an abacus with four spikes.
              Let us read the numbers shown on the abacuses below.

                                                                                                   Th   H    t    O




                                             Th H      t   O                                     Th H      t   O
                     Th   H    t    O     = 3     1    5   2             Th   H     t    O    = 5      3   0    8

                     If     = 1000,     = 100,    = 10 and   = 1, then represent the number 2571 using
                     these symbols.
