Sure! Here's an example of a simple Ti-84 calculator simulator implemented as a single HTML file using JavaScript:
This HTML file creates a calculator simulator with basic arithmetic operations (+, -, *, /), decimal dot (.), backspace (←), clear (C), and inverse (1/x) functionalities. The display element is an input field that shows the current value or error messages. You can interact with the calculator using the provided buttons.
Please note that this is a simplified example, and for a complete calculator simulator, you may need to handle more advanced features and edge cases.
