A simple web-based calculator built with HTML, CSS, and JavaScript.

Human-Written Code
This project was independently developed, using AI only as tool for troubleshooting and learning.
Hence this project demonstrates the acquired basic programming skills and an authentic learning progress.

Features

• Basic arithmetic operations: +, -, *, /, %
• Square root calculation
• Delete last character & clear input
• Keyboard support for numbers and operators
• Responsive layout with maximum input length based on screen size

Learning Goals

This project was created to practice collaboration between web technologies, with a focus on JavaScript:

• Event listeners (click and keydown)
• Loops (forEach)
• Functions (modular handling of operations, clear, delete, and sqrt)
• Input validation and responsive behavior

Usage

1. Open index.html in a browser.
2. Use the on-screen buttons or keyboard keys (0-9, +, -, *, /, %, s for √, Enter for =, Backspace, Delete).
