Place a number on the abacus

Step 2

    The value of a bead depends upon which


altobeads





hypobeads
  column is assumed to be the unit's column One unit in the left column is always ten times as large as one unit in the adjacent column to the right. Thus, if we assume that the first column on the right-hand side of the frame to be the unit's place, one hypobead in the first column will be worth one unit; one in the second column will beworth ten unit's, etc. Likewise one altobead in the first column will be five unit's; one in the second column will be
109  108   107   106   105  104   103   102 101   100     50 unit's, and so on.
