Isn't the calculator you're using too complex?
The calculator we are using right now has too many buttons.

This app has only the necessary buttons, so it's not too complicated and easy for us to see.

Do a simple calculation with this app.







Currently, this app allows you to perform calculations using only one sign.
The complex calculation function with multiple expressions, decimal point calculation, and smartphone compatibility problems (currently only compatible with LG G6 models) will be improved in the future.

This is the app I uploaded while learning coding in java. I'm still in the early stages so I'll ask for your support ~
