stonebro: You learn fractal geometry in high school now? Last time I checked fractals need the use of the complex number system and complex integration.
Anyway, fractals are awesome. They're how nature works.
lukaszthegreat: had fractals in High School too. Nothing VERY complex tough.
In math, complex refers to the set of all complex numbers, a+b*i, where a and b are real numbers and i is the square root of -1. Complex does not necessarily mean complicated.
Of course, they can dumb down anything for high school. I have read basic number theory books that didn't go into groups and rings, which is pretty much a crime in my opinion. It all comes down to how much detail your teachers and textbooks choose to divulge.
