In Spain too, it’s also needed in vocational training (FP1, FP2) for carpenters, electricians, plumbers, etc., because it involves necessary calculations in their work, such as trigonometry, spheronometry, vector forces, flow calculations, among others. For office workers, naturally, percentage calculations are not overcome, but even there second degree equations can arise.
Cause the middle school one is the quadratic formula. You use it to factor 2nd degree polynomials. You don’t solve for a, b, and c, you just plug them in.
That’s nuts. In the US the only high school math I was taught was algebra and geometry. Anything more advanced than that was for students in the “gifted” program. No wonder why Americans are so stupid.
not sure why you’re getting downvoted for this, I had the same experience with my education in the US. high school class of 08, lol. the school never taught a math class past algebra 1. if you finished it, you still needed math credits per year, so they’d just have you retake the same class. seriously. absolutely abysmal. 95% of the math I do now is self taught. from my “education” alone, we never got much past solving basic linear single-variable equations. most of my class graduated barely literate. really, most of my class simply left, myself included - the dropout rate was astonishingly high around 08, and instead of doing the same classes and curriculum for the third time in my senior year, I opted to simply leave, educate myself, and shortly thereafter start my business.
I’m American, I definitely learned this stuff in 7th or 8th grade. Granted, I didn’t use it past high school, and I forgot it before I finished college, but that’s definitely when I learned it.
Yeah seriously WTF, I didn’t even learn basic Algebra until freshmen year of high school! We never even got to the math with the fancy letters in it. I have no idea what those cursive f, d, and w characters mean.
Cursive big f: “integration”, which can be interpreted in two ways. One is “area under the curve” for some part of the curve. Other is “average value of a part of the curve multiplied by the size of that part of the curve”. Curve being the function, the graph, f(x), however you wanna call it.
Normal d: “differentiation” (from difference), infinitely small change. Usually used in ratios: df/dx means how much does f(x) change relative to x when you change x a little bit.
Cursive d: “partial”, same as normal d but used when working with higher dimensional data like 3D. Can also mean “boundary” of something. Example: boundary of a volume in 3D, like wrapping paper around a box. Or, boundary of such wrapping paper itself, if it’s not perfectly connecting.
Omega: just a Greek letter used as a variable, in this case there’s a history of it being used as a sort of “density” variable in the field of differential geometry. The college row in the meme is kind of translating the high school row from a function to a 3D volume.
It’s just calculus where admittedly my own education stopped but it’s still very helpful in finding values in real-world things like change of value in time. I still hope to one day develop a working knowledge of it, myself. u/…mir below me did a good job of summarizing the two main introductory concepts in much the same way i’ve read others simplify and describe the subject in classic 100+ yr old books like “Calculus Made Easy by Sylvanus Thompson.” I suspect it’s not as intimidating as it seems once a person gets past some basic fundamental concepts.
In Hong Kong too, though the dividing is a bit different. High school is like the last 3 years of secondary school, and middle school is like the 3 years in primary school and 3 years in secondary school.
We also have vector and matrix on top of calculus in high school if you take the elective course. The compulsory part contains geometry, complex, probability, etc.
Anecdotal, but I grew up in the US and I learned this in middle school as a gifted student. Others have mentioned it depends on the state/curriculum. I imagine in other countries they also divide their students between standard/honors/gifted-type tiers; they certainly do in the Netherlands, which is where I did my graduate studies.
YOU’RE DOING QUADRATICS IN MIDDLE SCHOOL?’
Yes, that’s standard at least in Germany

… The worst part is I’m decent with math by US standards in school and couldn’t even solve the middle school one with a quick glance.
Multiply the top by the bottom to erase it. Reverse the square root of something. + Or - threw me right off…

It is the quadratic formula. It already is the solution. The problem is any quadratic of the form ax²+bx+c=0
Same in Brazil, though public education quality varies a lot.

If you want, we have some samples. I took module 2. Compulsory Module 1: Calculus + Statistics Module 2: Algebra + Calculus
I guess you can see this earlier but in Europe you cover it in middle school
