## Overview

This is a browser-based calculator with basic and scientific calculations, plus tools for several mathematical domains. The main workflow is entering an expression or tool input, computing a result in the page’s JavaScript, and—where evidenced—recording it in calculation history. The source also implements offline caching. The README is empty, and the HTML and most of the main script were not sampled, so UI wiring and some feature interactions are not shown.

Main entry points: [`script.js`](https://github.com/archith2006/calculator/blob/main/script.js) (Calculator logic), [`service-worker.js`](https://github.com/archith2006/calculator/blob/main/service-worker.js) (Offline worker), [`index.html`](https://github.com/archith2006/calculator/blob/main/index.html) (Calculator page)
