I think that it is a US specific obsession.

I don't even know what "calculus" is really.

I have had plenty of math classes both in high school and later at university but I don't recall any significant distinction that would leave me with some concrete idea of "algebra" vs. "calculus" vs. "whatever" years later.

I believe it was called "mathematical analysis" in my corner of the world. In high school and uni.

It's the continuity/limits/integrals stuff.

Also it was never optional. Either in high school or CS at uni.

In the US we'd reserve "mathematical analysis" (or more specifically, Real analysis) to the college level classes which involve writing proofs about the continuity of functions between sets of real numbers. You'd probably end up with a lecture on the mean value theorem here, and leave with the ability to prove it, among other things

"Calculus" is the application of that theory without argument. It's an advanced high school class or an early college one. There you'll integrate or differentiate real valued functions for use in optimisation problems or for determining qualitative features of such a function (e.g. where is it flat, where is it defined, etc).

In the US, you can probably pass calculus without writing a proof, but you can't pass mathematical analysis without at least understanding epsilon/delta proofs.

I'm pretty sure we did proofs in high school. But that was a while ago, don't know what they do now.

Hey now that I think of it, "mathematical analysis" had continuity, limits, some integrals. And then every mathematically inclined uni specialization had "integral and differential calculations (let's shorten it to calculus)" which was more advanced use of integrals :)

A rose by any other name would smell as sweet, but it may be called a thorn in a different locale.

In Poland we do those in high school. :)

In the US, our education system kind of sucks (:

I also did these in my good but non-elite American public high school.
