Having learnt the basic additions and subtractions, let us advance to little more advanced problems in this section. Second step of adding and subtracting 1`4 It would be easy to perform the calculation if you think that 7 is sum of 5 and 2, 8 is sum of 5 and 3 and 9 is sum of 5 and 4.
Subtraction of 6 is done by moving the five-bead and a one-bead away from the crossbar.Īdding and subtracting numbers up to 9 can be done in the similar way. Similarly, for adding 6 you need to move a five-bead and an one-bead towards the crossbar. You can use your forefinger for performing this task. Learning abacus not only improves your mental calculation, it also improves your brain function and your hand- eye coordination too. Moving it towards the cross bar means adding five and moving it away from the cross bar means subtracting five. To make it more accessible for those that are interested to learn abacus, Online Soroban has managed to create a platform where you can learn this age old skill, all in the comfort of your own home. However, for adding numbers above 4, we need to use the five-beads.įive-beads can be used by shifting them down to the cross bar. We learned above that the adding and subtracting numbers up to 4 can be done by using the one-beads. adding, subtracting etc in the following sections.Īddition and subtraction of one digit numbersįirst step of adding and subtracting 1`4īasically, addition is performed by moving beads towards the crossbar by using thumbĪnd subtraction is performed by moving a bead away from the crossbar as shown in the Figure.įor example, addition and subtraction of 1, 2, 3 and 4 is done by moving up or down the 1, 2, 3, and 4 one-beads respectively.įirst step of adding and subtracting 5`9

Now you are all set to learn how to do basic calculations using soroban i.e. The results agree with previous studies, which also report superior auditory performance and enhanced auditory working memory in children with abacus training.Soroban Piazza -Japanese Abacus Addition and Subtraction The results also showed moderate to strong correlation (r = 0.53–0.84) between the abacus levels and scores and reaction time for the auditory working memory tests.Conclusions The children with the abacus training group were taking intensive abacus training in the range of 2–4 years.ResultsThe results of the study revealed that children with abacus training had significantly better reaction time and scores than children without abacus training with effect size between 0.73 and 0.91 which suggests a strong difference. The participants were divided based on those with and without abacus training between the age of 9–13 years. The study was carried out to compare the score and reaction time for digit forward test, digit backward, ascending digit span and descending digit span test in individuals with and without abacus training and to correlate the level of abacus training with the scores and reaction time for all the tests in individuals with abacus training.
In the present study, it is attempted to examine the difference in the auditory working memory of the children with abacus training and children without abacus training.Methods
