Features くりあがりのあるたしざん・くりさがりのあるひきざん

■ An app for practicing the basics of Tashizan with a curl and Hikizan with a curl (Target: 1st grade elementary school students)■ You can practice so that there is no glance at the answer when you see a child practicing using the school materials Keisan Kaado (Tashizankaado, Hikizankaado) just glancing at the answer.
Developed as an app.■ The problem is the calculation in Keisankaado (Tashizankaado, Hikizankaado) where the answer is 11-18 and the answer is 2-9.■ The answer is a selection format (a format to select by pressing a button)■ You can choose between two modes, one that you can practice in order and the other that you can practice randomly.■ With a function to measure practice time (useful when recording time for homework)■ If you practice aloud, the practice effect may improve (?)■ Since children remembered the button layout when practicing and started to solve it by memory, we added a function to randomize the button layout.
