This calculator looks and behaves like a normal calculator... until you press the equals button! No matter what numbers or operations you enter, the result will always be "HELLO WORLD" with a fun rainbow animation.

Perfect for:

• Pranking friends
• Fun coding demonstrations
• Learning about DOM manipulation
• GitHub Pages deployment practice

Simply visit the deployed page and start calculating!

1. Clone this repository
2. Open index.html in your web browser
3. Start "calculating"!

• index.html - Main HTML structure with embedded CSS
• calculator.js - JavaScript logic (with the funny twist!)
• README.md - This file

1. Push this code to a GitHub repository
2. Go to repository Settings
3. Navigate to Pages section
4. Select main branch as source
5. Save and wait a few minutes
6. Your calculator will be live!

The calculator appears to work normally:

• You can input numbers
• You can select operations (+, -, ×, /)
• It displays your calculation

But when you press equals (=), instead of calculating the result, it:

1. Adds a shake animation
2. Displays "HELLO WORLD" in rainbow colors
3. Logs a fun message to the console

• 0-9 - Number input
• +, -, *, / - Operators
• Enter or = - Calculate (show HELLO WORLD)
• Escape or C - Clear
• . - Decimal point

• HTML5
• CSS3 (with animations and gradients)
• Vanilla JavaScript (no frameworks needed!)

Want to change the result? Edit the showHelloWorld() function in calculator.js:

function showHelloWorld() {
    currentDisplay = 'YOUR MESSAGE HERE';
    // ... rest of the code
}

Works on all modern browsers:

• Chrome
• Firefox
• Safari
• Edge
