Funny math

#2 and 6 are my favorites. #5 isn't that funny, but actually a clever problem.

If I laughed, does that mean I'm a nerd?

Expand.

I loved #3.

I love 3 and 6.

 

[Stormrage]

Wait.. I used to do math like that

 

[Snow]

I liked 6

5 is due to the fact that the outline of those two 'triangles' is not the same.

#5: yep, the triangles aren't identical (the angles of the hypotenusa's aren't identical). so it's basically an optical illusion.

I also loved #3 and #6

About the #1 (not directly related)
I've forgotten, is -oo = oo (where that oo means infinite)?

Expand was awesomeness. I wish I saw this yesterday before my math test.

 

[LLXerxes]

Half the people I know wouldn't understand a single one of those

 

[Heretic_Cata]

LOL, someone actually showed the one with sinx to my calculus teacher.

 

[Mirc]

I love 1, 2, 3 and 6! They are awesome!

 

[RameNoodle]

Math jokes?
I love 'em!

No.

Personally I loved 4, because I've done that before. 3 was pretty good too.

#5: yep, the triangles aren't identical (the angles of the hypotenusa's aren't identical). so it's basically an optical illusion.

what? the angle of the hypotenuse is always 90 degrees isn't it (otherwise it isn't a hypotenuse) and all the angels look the same. they start on the same x-coordinate lines and are both 5 high

The hypotenuses aren't perfectly straight. If you look carefully, at the point where the blue and red triangles touch, the one on the top bends inwards, and the one on the bottom bends outwards. You can verify by noting that the point of intersection is above the horizontal line two squares up from the bottom of the triangle on the bottom trangle, but below the same line on the top triangle.

EDIT: I don't think I was clear on which point I meant. It's the point with a T(5,2) from A and D.
