Presently, people tend to use modern calculator compared to old abacus. Maybe it's because most of people thought that calculator more faster, more reliable and more accurate. Absolutely not. In fact, beyond learning mental math skills you would not always have a calculator handy. Learning the abacus provides essential problem solving, focus and, of course math skills. Abacus is the best way for all children to learn how to calculate without the dependency of a calculator. In addition, because the abacus is both visual and mental in nature, it fosters both left and right brain activity.
Besides using calculator, abacus also can solve basic and advanced math problems with an understanding of the Abacus, including addition, subtraction, multiplication and division, as well as square root, cube root and even bank interest. As example on November 12, 1946, a contest was held in Tokyo between the Japanese Soroban, used by Kiyoshi Matsuzaki, and an electric calculator, operated by US Army Private Thomas Nathan Wood. The bases for scoring in the contest were speed and accuracy of results in all four basic arithmetic operations and a problem which combines all four. The Soroban won 4 to 1, with the electric calculator prevailing in multiplication.
Previously, calculators were not allowed on standardized mathematics examinations even for blind students. In addition, talking calculaters were also not allowed on most classroom examinations as well. Therefore, blind students were at a distinct disadvantage if they did not have an equivalent to the sighted student's pencil and paper. In the end, only abacus can help them in any way.
In general, most of people thought that the abacus is not user-friendly. The abacus can be too difficult for some students however, the student needs and abilities must always be your primary consideration. However, before giving up, check to see if there is a better method of calculating on the abacus than the present one.
