Okay, I can create a simple website calculator for you using HTML, CSS, and JavaScript.

This sets up the basic structure, styling, and functionality for your calculator. You can open the index.html file in your browser preview to use it.

Okay, I've reviewed the JavaScript code and made some refinements to ensure the operator logic works correctly and handles various scenarios robustly.

I've restructured the script.js slightly using common calculator state variables (currentOperand, previousOperand, operation) which often makes the logic clearer. I also renamed some functions for better clarity (e.g., chooseOperation, compute). This should provide a fully functional calculator.
