  • XP I HATE STINKING MATH!!!! I DONT GET IT!!!!!

  • How do i find the surface area of a sphere in terms of pi?

  • This pathetic excuse for a teacher embodies the reason why schools devour the natural, inborn curiosity of children and gut all the fun out of learning. After 1 minute of listening to her vapid droning, I would rather shoot myself than continue.

  • What's the volume of my dick?

  • the awkward smile at the end...

  • :O I get it ! Thank you so much

  • but how do you know the area is 4 pi r squared

    and the volume is (4/3) pi r cubed?

    cheaters.... do some calculus

  • Imagine how awkward going on a date with her would be. Not that you'd want to XD

  • she looks like someone's pointing a gun at her behind the camera.

  • it makes sense but there are shorter and more basic ways to do this, i mean seriously wtf?
