Script

Below is an example of a simple calculator app implemented as a single HTML file using JavaScript, enclosed in script tags. This calculator can perform basic mathematical operations and is designed for smartphone operation, using pictograms where possible.

Calculator

The HTML file defines a simple UI for the calculator with buttons for numbers, basic operation symbols, and control buttons. The JavaScript code handles the logic for appending characters to the current input, performing calculations, and updating the result on the screen. The `eval()` function is used to evaluate the string expression entered by the user. Note that this is a basic example and might not cover all edge cases or advanced functionalities of a TI-84 Plus CE calculator. However, it should give you a starting point to build upon.
