Imaginary Numbers

Imaginary numbers. Imaginary numbers are ******! What's the point?! In our Algebra II class, we're learning about them and so far, I don't see a point! The whole concept is i = the square root of -1. Seriously? That's your ingenious idea for an imaginary number?! How did they even come up with that?

"Hey, guys! You know how we haven't been able to come up with an answer for the square root of negative numbers? Well, I got an idea!"
"What is it?!"
"How about the square root of -1 equals i!"

What the hell? How does that help?! I don't see the difference! All they did was assign a freaking variable for a number they didn't know! Ooo... how creative! So if you don't know the answer to a problem, just put down 'a', and then define the variable as the answer to the problem. That's all they did! Because I can really see how that will help you solve a problem! For example: 1 + square root of -1. Hey, what's the answer? It's 1 + i. Well what's i? I'll tell you what it is. IT'S THE FREAKING SQUARE ROOT OF -1! Oh, THAT really helped! Great job guys. I don't know when I will EVER need to know the square root of -1. Oh wait, I already know what it is! IT'S 'I'! Great, just another math thing I will NEVER use in real life! Why would I use IMAGINARY numbers in REAL life?! Sorry, but if someone asks me how much sales are up by, I would never say 'i'!
