mini-test

[PGSch]

Please make a small and simple package for basic mathematical calculation. Use a structure similar to the following:

supermath/
├── .gitignore
├── README.md
├── requirements.txt
├── setup.py
└── src/
└── my_package/
├── init.py
└── main.py

Be very careful about your 128K token limit. The provided exemplary code should be functional as package, while also very lean with as little code as possible to make it functional.
