I should clarify that these are the elementary ed students. I've personally taught students training to become high school math teachers, and they have been pretty good.

As the other answers point out, it follows from explicit computation. Let me add that there's no particularly good a priori reason to expect this particular coincidence. It just happens.

This is not necessarily true. (I am a professor.) In general I would like to be able to refuse review requests for journals that rip off their (institutional) customers. Under the circumstances, I dare not do so, because these requests usua

I don't know of a good writeup, but y^3 - y = 0, or alternatively x^3 - x = 0, among other polynomials, is what you want. In "ordinary" algebra, typically we consider polynomials of one variable, which we write f(x). The grap

Unfortunate to hear this about Caltech. Nevertheless, as a graduate, I hope you regard it as self-evident that, even if your alma mater has slipped, it still deserves a place in the top 98%?

I know people who have worked at places like Bell Labs for awhile and then gone back to academia. It's not easy, but if you succeed (and publish) then you can often get an academic job afterwards.
