A web-based calculator built using Flask (Python) as the backend. This app allows users to perform basic arithmetic operations — addition, subtraction, multiplication, and division — through a clean and responsive web interface. The calculation is handled server-side, and results are displayed in real-time after form submission.
- ✅ Perform basic arithmetic operations
