i know pi, and honestly, contrary to what the pic said you're just an uneducated moron if you don't. never seen the i sign though, but you're not alone.
well, pi is something that is in 5th grade of elementary school - you know, basic geometry, like a level higher than the Pythagorean theorem.
Everyone should know pi at least, even in America.
@Preach:
Complex number [i*i=(-2)] is somewhat around the end of our high schools. As you might now there's no actual number that equals "i" in that case. That's why complex numbers got invented. It's a stupid shit but unfortunately useful when you do programming and don't want to get an error with numbers that can't be achieved with actual numbers.
Yeah, it was the whole rational/real thing and then reading the statement at the bottom which made me lol as it describes half the people in my math class.
Actually, no. I felt like checking up because i'll be damned if some polish asshole is gonna know this and i don't
The "i" denotes an imaginary unit. The symbol used is not a regular lower case "i" (maybe in the pic but then the pic is wrong), but an iota. The imaginary unit is used for equations that don't have a solution in the form of a real number, like x^2 = -1

That is correct. If it could be just "x" or "y" then the number is unknown but still real. The iota is in calculus and beyond and like preach said, isn't real. I hope I don't have to see "i" again in Calculus 2, which I am not taking.
