                  4-Digit Numbers oN the abaCus

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

                  Let us read the numbers shown on these abacus.
                                                                                                       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

                           Think and Answer

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