This example shows a fully functional calculator application built with React and styled using Tailwind CSS. It supports basic arithmetic operations (addition, subtraction, multiplication, division), percentage calculation, sign toggling, decimal input, and clear/reset functionality. The interface displays the current value and operation history, with buttons that respond to clicks and update state via React’s `useState` hook. The app uses Tailwind’s utility classes and custom theme colors to create a clean, responsive grid-based layout.
