This app can generate formulas and train as many times as you want to do abacus. The app will display the formula and the user can flip the abacus and perform the calculation, multiplication and division as many times as they like. lines can specify the number of number calculations. We plan to release a Japanese version of this app as the number of users increases.
Division confirmed a bug with the research function. Please use without pressing the research button. An improvement update is undecided.
This app has not completed the division of version 2, so if you install version 1, please use only the integer part of the division. Decimal point operation is not recommended as it will result in misunderstandings.
Furthermore, there is a concept of Create for the Abacus ver, 3. with new functions added to Create for the Abacus ver, 2. We would like to develop it and publish it for a fee.
