Software for Improving Numerical Calculation Skills

Currently, various languages are used not only in Japan but also in other countries. Similarly, arithmetical computations are performed in various countries and various aspects of our life. Having skills of numerical calculations help people live a more comfortable and convenient life. Certainly, people can lead lives without arithmetical calculations. But in modern society, capability in computation is getting more and more essential. In Japan, compulsory education starts from elementary school and children learn calculation and reading and writing. But, if children dislike arithmetical study at this stage, they would obviously learn less, and it would be very hard to make up for that lost time. Therefore I developed this software to help such children.
