        Show Numeral On The Abacus

        An  abacus is a  counting  tool.  A four  pin abacus  can  be  used  to  show

        numeral of a four digit number.

        Suppose we wish to show 4562 on the abacus.

                      4562 = 4 thousands + 5 hundreds + 6 tens + 2 ones.

        This  can  be  shown  by  4  beads  on  Th,  5  beads  on  H  ,  6  beads  on  T  and
        2 beads on O.
