If you ever come into contact with an abacus, what do you do? You might want to learn how to use it. These suanpans can be used for doing division, multiplication and for taking square roots and cube roots as well if the user knows the techniques. Chinese can also use their abacuses for decimal computations. The Roman and Japanese versions are designed for base 10 computations. Chinese abacuses are designed to allow for hexadecimal computation. The Chinese kind has two beads on the rods on one side and 5 beads on the rods on the other side of the divider.
There is a divider that separates the left and right strings of beads. The Chinese kind has beads strung on wires or thin wood rods. It was mentioned in a 2nd century BC Chinese document, and versions may have been used for thousands of years prior. The abacus is called “suanpan” (算盤, calculating pan) in China. The Chinese abacus has a long history, and using one is actually simple though it takes practice to use it proficiently. In fact, it isn’t clear where it was invented. Similar abacuses were used since ancient times in the Western world and India also. It wasn’t only the Chinese who used abacuses. I couldn’t figure out how they were used and felt kind of stupid because people were obviously calculating faster than I could. I remember when I first saw them, I was kind of dumbfounded. Up until calculators and teller machines became so cheap in China, they were widely used. In China, in outlying towns or more backward areas, you might see one lying around or actually used if you go into a shop.
