Hey!!

For all you visual learners out there who dont understand FRAT PRANE (like me), I think this is a very useful video! xD

WARNING: this video is NOT FOR math pros such as shijie!!

Yeap. Like.. i FINALLY SAW THE LIGHTTTT after looking at this video.

And then i wonder why i'm paying school fees to the school, but not youtube. ^^

Oh wells. wonders of the world indeed.

Hope this helps all you poor and lost souls out there!!! (or maybe its just hanyi and i LOL)

Thanks!

Yuhe
