正の数・負の数トランプゲーム for PC

It is an application to practice the calculation of positive and negative numbers, which is learned in the mathematics of the first grade of junior high school.
I made it on the assumption that it will be used in math classes, but it can also be used in home study.

An explanation video is also included so that you can play even if you have not learned positive and negative numbers yet.
Please see from how to play on the top screen.

If you have any problems or improvements, please feel free to contact us.
However, please note that we cannot implement difficult functions because we are new to application development.

This app is a completely free app with no ads.
Since the development cost is my own expense, I would be grateful if you could support me from within the app.
However, the support does not make any changes in the app.
Since it is used as a teaching material at school, it is designed so that no sound is produced.

If you would like to introduce it at the school as part of the GIGA school concept, please let us know by using the inquiry form and it will be encouraging.
