# ArthimeticOp

**ArthimeticOp** is a lightweight Python package that provides basic arithmetic operations — addition, subtraction, multiplication, and division — via simple, reusable functions.

## 📦 Features

- `add(a, b)` – Returns the sum of `a` and `b`.
- `subtract(a, b)` – Returns the result of `a - b`.
- `multiply(a, b)` – Returns the product of `a` and `b`.
- `divide(a, b)` – Returns the result of `a / b`. Raises `ValueError` on division by zero.

## 🔧 Installation

Install from [PyPI](https://pypi.org/project/ArthimeticOp/) using pip:

```bash
pip install ArthimeticOp
````

Or directly from GitHub:

```bash
pip install git+https://github.com/postboxat18/ArthimeticOp.git
```

## 🚀 Usage

```python
from ArthimeticOp.ArthimeticOp import add, subtract, multiply, divide

print(add(4, 5))        # Output: 9
print(subtract(10, 3))  # Output: 7
print(multiply(6, 7))   # Output: 42
print(divide(8, 2))     # Output: 4.0

# Handle division by zero
try:
    divide(5, 0)
except ValueError as e:
    print(f"Error: {e}")  # Output: Error: Cannot divide by zero.
```

## ⚠️ Error Handling

The `divide(a, b)` function checks for division by zero and raises a `ValueError` if `b == 0`. Always use try-except blocks when dividing.

### ✅ Notes:

- Make sure the folder structure supports:  
  `from ArthimeticOp.ArthimeticOp import ...`  
  That means your package directory should be:
```

ArthimeticOp/

└── ArthimeticOp.py

└── **init**.py

```

- Adjust the PyPI package name in your `pyproject.toml` to match `ArthimeticOp`.

If you need a matching `LICENSE` file or setup structure, just let me know.
