Okay, when a website's title is "Humor in der Mathematik," you can be pretty sure it's not real. Both links you provided are jokes.

2+2=5
For extremely large values of 2.

LOL, those are some funny links, Erdem, thanks!

Do you mean that "Houston Euler" is not a real mathematician?
 
Back in High School we used to say "Euler's number" = five quarts.
 
I first heard of the equation when reading 1984 . . .
 
Does anybody ever keep up with pop culture?

You probably saw the

2 + 2 = 5

equation on the back of the new Radiohead album called "Hail To The Thief."

I think they relesed the single in the UK last week so you can go buy it if you want!
 
The radiohead single was an obvious allusion to the Orwellian novel

I don't speak German. What does "humor" mean?
 
Good question russ_watters. Last time I checked, I think it was some sort of body fluid.
