  How does an abacus differ from a Chinese abacus?

  Instead of two rows of beads in the upper deck, there is only one row. In the lower deck, instead of five rows of beads, there are only four. The beads equal the same amount as in the Chinese abacus, but with one less bead, there is no carrying of numbers.

  What do the beads on an abacus mean?

  Beads represent quantity while the beads’ position represents value. When you get an abacus you will notice that it is divided into two parts. Given an abacus with 13 rows of which there are five beads, then, the lower part contains four beads while the upper part has only one bead.

  How is the abacus used to do math?

  It can be used to count, add, subtract, multiply and more. The most common abacus is split into two basic rows: the bottom row for the “ones”. There are two beads in the top row, and five beads in the bottom one. For example, 7 can be made by using one bead on the top row, and 2 beads from the bottom row, because 5 + 2 = 7

  What kind of material is an abacus made of?

  A modern abacus is made of wood or plastic. It consists of a rectangular frame about the size of a shoe-box lid. Within the frame are at least nine vertical rods strung with moveable beads. A horizontal crossbar perpendicular to the rods separates the abacus into two unequal parts.
