Samsung-like Calculator App

A sleek and modern calculator application inspired by the Samsung Calculator. This project replicates the functionality and design of the Samsung Calculator, offering a user-friendly interface with advanced features like parentheses, percentage calculations, and error handling.

Features

• Basic Arithmetic Operations: Addition, subtraction, multiplication, and division.
• Parentheses Support: Easily manage complex calculations with nested parentheses.
• Percentage Calculations: Quickly calculate percentages with the dedicated % button.
• Error Handling: Displays error messages for invalid operations (e.g., division by zero).
• Negative Numbers: Toggle between positive and negative numbers using the +/- button.
• Decimal Point: Supports decimal calculations with the . button.
• Clear and Delete: Clear the entire display with C or delete the last character with ⌫.
• Responsive Design: Fully responsive layout that works on both mobile and desktop screens.
• Aesthetic Design: Clean and modern UI with smooth animations and green accents.

Functionality

• Parentheses Logic: Automatically handles opening and closing parentheses, ensuring balanced expressions.
• Operator Precedence: Follows standard mathematical rules for operator precedence (PEMDAS/BODMAS).
• Real-time Display: Shows the current calculation with a blinking green cursor.
• Error Popup: Displays a temporary error message for invalid operations (e.g., division by zero).
• Color-coded Operators: Operators (+, -, ×, ÷) are highlighted in green for better visibility.
• Parentheses Highlighting: The last pair of parentheses is highlighted in green for clarity.

How to Use

1. Basic Calculations:

   • Enter numbers using the numeric buttons (0-9).
   • Use the operator buttons (+, -, ×, ÷) to perform calculations.
   • Press = to get the result.

2. Parentheses:

   • Use the () button to add parentheses for complex calculations.
   • The calculator automatically balances parentheses and highlights the last pair in green.

3. Percentage Calculations:

   • Enter a number and press % to calculate its percentage.
   • For example, 50 % will display 0.5.

4. Negative Numbers:

   • Use the +/- button to toggle between positive and negative numbers.

5. Decimal Point:

   • Use the . button to add decimal points for precise calculations.

6. Clear and Delete:

   • Press C to clear the entire display.
   • Press ⌫ to delete the last character.

7. Error Handling:

   • If an invalid operation is performed (e.g., division by zero), an error message will pop up temporarily.
