Prerequisites: Python 3.9+, pip

# Clone the repository

pip install -r requirements.txt

# Run the application
python app.py

Basic Calculations:

• Click the number buttons or use your keyboard to enter numbers
• Select an operation (+, -, *, /)
• Press = or Enter to see the result

Special Functions:

• AC — Clears everything and resets to zero
• +/- — Changes the sign of the current number
• % — Calculates the percentage of the current number

Decimal Numbers:

• Use the . button or press . on your keyboard
• The calculator prevents multiple decimal points

Error Recovery:

• If you see "Error" (usually from division by zero), press AC to continue

The application allows you to create desktop entries directly from the menu:

1. Go to File → Create Desktop Entry
2. Choose locations:
   • ✓ Application Menu (~/.local/share/applications/)
   • □ Desktop (~/Desktop/)
3. Click "Create Entry"

What happens:

• Creates .desktop file(s) with proper configuration
• Sets executable permissions automatically
• Uses application icon if available

Note: This feature is only available on Linux systems with desktop environments that support .desktop files (GNOME, KDE, XFCE, etc.).
