【overview】

This app is for textbook-level calculations for middle school and high school mathematics.

It is a scientific calculator app (something like).

Calculations in this calculator app primarily use Python's SymPy.

SymPy is a highly functional and versatile library.

This calculator app uses only very simple functions of SymPy.

It is not a high-performance, multi-functional calculator app like other popular similar apps.

Thank you for your understanding.

The position of this calculator app is:

Although it is more functional than the simple calculator app that comes pre-installed on smartphones and tablets.

It feels like it is nowhere near the high-performance and multi-functional calculator apps of popular similar apps.

This is a mid-range calculator app that is located between them.

・Many simple calculations for middle school and high school mathematics can be done.

・Calculations in university mathematics and professional mathematics are often impossible.

I would appreciate it if you could include this in advance.

*My stance is that it doesn't matter if you can't do calculations in university mathematics or professional mathematics.

We are creating this calculator app, so we appreciate your understanding.

Some of them may not even be able to calculate high school mathematics...
