How prasad0876/calculator works
This is a browser-based calculator. Users enter expressions with on-screen buttons or the keyboard, then calculate a result; the interface also supports clearing, deleting, percentage and decimal input, and displays invalid-expression errors. The README documents responsive desktop and mobile design. The source shows the interaction and calculation logic, but the HTML and CSS contents were not sampled, so their specific structure and styling details are not represented.
