A simple, responsive web-based calculator built with HTML, CSS, and JavaScript.
This project performs basic arithmetic operations and is designed to be beginner-friendly, making it a good starting point for contributors.

• Basic operations: addition, subtraction, multiplication, division
• Clear (C) and equals (=) functionality
• Responsive UI with styled buttons
• Error handling for invalid inputs
• Lightweight and fast – no dependencies

You can run the calculator locally by opening index.html in your browser.
(Optionally, maintainers can enable GitHub Pages for a live demo.)

1. Clone the repository:

   git clone https://github.com/codeshiva10/calculator.git

2. Navigate into the folder:

   cd calculator

3. Open index.html in your browser. That’s it!
