Subject: [PATCH] Improve code organization and structure

Rename and refactor example files, and update README.

* **Refactor `example1.py`**:
  - Rename `presentation/examples/example1.py` to `presentation/examples/math_operations/example1.py`
  - Add type hints to `add`, `subtract`, `multiply`, and `divide` functions
  - Refactor `divide` function to handle division by zero more gracefully

* **Refactor `example2.py`**:
  - Rename `presentation/examples/example2.py` to `presentation/examples/greetings/example2.py`
  - Add type hints to `greet`, `farewell`, and `main` functions
  - Refactor `main` function to accept a name as an argument

* **Update `README.md`**:
  - Update paths of example code files in the `examples/` directory
  - Add brief description of new subdirectories `math_operations` and `greetings`
