Abacus System $54.86 High Quality Content by WIKIPEDIA articles The abacus system of mental calculation is a system where users mentally visualize an abacus to do calculations. No physical abacus is used; only the answers are written down. This system is being propagated in China, Singapore, South Korea, Thailand, Malaysia, and Japan. Mental calculation is said to improve mental capability, increases speed of response, memory power, and concentration power. Many veteran and prolific abacus users in China, Japan, South Korea, and others who use the abacus daily, naturally tend to not use the abacus anymore but perform calculations by visualizing the abacus. This was verified when the right brain measured heightened EEG activity when calculating and compared with nonveterans who were using the abacus to perform calculations. The standard abacus can be used to perform addition, subtraction, division, and multiplication; the abacus can also be used to extract squareroots and cubic roots.

Roman Abacus $79.66 High Quality Content by WIKIPEDIA articles The Romans developed the Roman hand abacus, a portable, but less capable, base10 version of the previous Babylonian abacus. It was the first portable calculating device for engineers, merchants and presumably tax collectors. It greatly reduced the time needed to perform the basic operations of Roman arithmetic using Roman numerals. As Karl Menninger says on page 315 of his book, For more extensive and complicated calculations, such as those involved in Roman land surveys, there was, in addition to the hand abacus, a true reckoning board with unattached counters or pebbles.

Logical Abacus $93.99 High Quality Content by WIKIPEDIA articles A logical abacus is a mechanical digital computer.Also referred to as a logical machine, the logical abacus is analogous to the ordinary (mathematical) abacus. It is based on the principle of truth tables.It is constructed to show all the possible combinations of a set of logical terms with their negatives, and, further, the way in which these combinations are affected by the addition of attributes or other limiting words, i.e., to simplify mechanically the solution of logical problems. These instruments are all more or less elaborate developments of the logical slate, on which were written in vertical columns all the combinations of symbols or letters which could be made logically out of a definite number of terms. These were compared with any given premises, and those which were incompatible were crossed off. In the abacus the combinations are inscribed each on a single slip of wood or similar substance, which is moved by a key; incompatible combinations can thus be mechanically removed at will, in accordance with any given series of premises. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.
