+# Calculator Project Readme
+
+This project is a simple calculator implemented using HTML, CSS, and JavaScript. It allows users to perform basic arithmetic operations, view computation history, and clear the history.
+
+## Features
+
+### Calculator Operations
+
+- Addition (`+`)
+- Subtraction (`-`)
+- Multiplication (`*`)
+- Division (`÷`)
+- Percentage (`%`)
+- Toggle Sign (`+/-`)
+- Clear All (`AC`)
+- Delete Last Entry (`DE`)
+- Decimal Point (`.`)
+
+### Computation History
+
+- Users can view a history of their computations.
+- The history is limited to the last 10 entries.
+
+### Clear History
+
+- Users can clear the computation history by clicking the "Clear History" button.
+
+### Toggle History Visibility
+
+- Users can toggle the visibility of the computation history by clicking the "History" button.
+
+## Usage
+
+1. **Performing Calculations**
+
+   - Click on the digits (`0-9`) to input numbers.
+   - Use the arithmetic operation buttons (`+, -, *, ÷, %`) for calculations.
+   - Click the "=" button to see the result on the screen.
+   - Use the "AC" button to clear all entries.
+   - Use the "DE" button to delete the last entry.
+   - Toggle the sign of a number using the "+/-" button.
+   - Add decimal points using the "." button.
+
+2. **Viewing Computation History**
+
+   - Click on the "history" button to toggle the visibility of the computation history.
+   - The history displays the last 10 computation entries.
+
+3. **Clearing History**
+
+   - Click on the "Clear History" button to remove all computation history.
+
+## Project Structure
+
+- **HTML (`index.html`):**
+  - Defines the structure of the calculator and computation history.
+  - Includes necessary elements and classes.
+
+- **CSS (`index.css`):**
+  - Styles the calculator and computation history elements.
+  - Implements transitions and animations for a smoother user experience.
+
+- **JavaScript (`index.js`):**
+  - Defines functionality for the calculator operations.
+  - Handles user interactions and updates the screen accordingly.
+  - Manages computation history and its visibility.
+
+## Dependencies
+
+- The project has no external dependencies and runs on basic HTML, CSS, and JavaScript.
+
+## Development and Contributions
+
+- This project is open for contributions.
+- Feel free to enhance and extend the functionality.
+- Follow common coding standards and practices.
+- Submit pull requests for review.
