YOU’RE DOING QUADRATICS IN MIDDLE SCHOOL?’

[–] hydroptic@sopuli.xyz 0 points 7 months ago* (last edited 7 months ago) (1 children)

Yeah it was a middle school thing in Finland too, at least in the 90's.

I did an exchange year in the US in my 2nd high school year, and I was honestly a bit surprised at how… well, simple it all was. I was a senior in the US and I'd learned just about everything they taught that wasn't specific to the US or the English language (and even some of those…) either in my 1st year in high school or in middle school.

In my experience as an American, I've learned the same thing in multiple years, we kind of just chose a point to stop at and did that for our entire god damn school year, never moving on. We could have talked about so much interesting history, but no, we need to talk about WW2 and completely gloss over most other things for the 12th year in a row

For christs sakes I was learning FRACTIONS AND DECIMALS IN MY SENIOR YEAR

[–] JJROKCZ@lemmy.world 0 points 7 months ago (1 children)

Are you sure you weren’t in a remedial school? lol

[–] Denvil@lemmy.one 0 points 7 months ago* (last edited 7 months ago) (3 children)

I will admit the reason my last two years were such a stark contrast to my previous years was because I went from honors down to basic because I went to a vocational high school, Diamond Oaks, and they only had the base classes

But still I never want to have another history class on WW2 again, I don't mind learning the era but I've relearned the same thing over and over again

Yes, that's standard at least in Germany

[–] blanketswithsmallpox@lemmy.world 0 points 7 months ago (2 children)

... The worst part is I'm decent with math by US standards in school and couldn't even solve the middle school one with. Quick glance.

Multiply the top by the bottom to erase it. Reverse the square root of something. + Or - threw me right off...

[–] Xavienth@lemmygrad.ml 0 points 7 months ago

It is the quadratic formula. It already is the solution. The problem is any quadratic of the form ax²+bx+c=0

[–] GiveMemes@jlai.lu 0 points 7 months ago

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.

[–] Zerush@lemmy.ml 0 points 7 months ago* (last edited 7 months ago) (2 children)

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.

[–] Steve@startrek.website 0 points 7 months ago (1 children)

Wow. In America, trades people use a chart to look up literally anything that requires math. If you’re lucky.

Most of the time “it looks good enough” is enough.

[–] Tar_alcaran@sh.itjust.works 0 points 7 months ago* (last edited 7 months ago) (1 children)

I've had an economics teacher in the Netherlands who had interest tables and wanted us to them too. For those before calculators, those are tables that list the years on the left, and the interest on top, and then the multiplier in the table.

So, 10 years at 6.5% = 1.877

This was in 2005i sh.

[–] Omniraptor@lemm.ee 0 points 7 months ago (2 children)

Could you use a slide rule for that kind of multiplication?

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.

Idk what middle school really is because it's not been a thing at any of the schools I've been to, but it's definitely something you do a lot earlier than calculus. If calculus comes in in your last three or four years of high school, quadratics are what you're doing for at least two years before that.

[–] hydroptic@sopuli.xyz 0 points 7 months ago* (last edited 7 months ago) (1 children)

It's the step between primary and secondary school that a lot of countries have, also known as intermediate school, junior high school, junior secondary school, or lower secondary school: https://en.wikipedia.org/wiki/Middle_school

Middle school is usually grades 7-8

[–] NorthWestWind@lemmy.world 0 points 7 months ago* (last edited 7 months ago)

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.

If you want, we have some samples. I took module 2. Compulsory Module 1: Calculus + Statistics Module 2: Algebra + Calculus

[–] pjwestin@lemmy.world 0 points 7 months ago (1 children)

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.

[–] 4am@lemm.ee 0 points 7 months ago* (last edited 7 months ago) (1 children)

Bro I’m American and they didn’t even mention algebra until 9th grade, the fuck you mean quadratics in middle school

[–] Blue_Morpho@lemmy.world 0 points 7 months ago (1 children)

Math is personalized in American schools. There's on grade, advanced, gt, and accelerated. Each level above on grade is how many years ahead your class math is. Depending on how large your school is, gt and accelerated math students will take math with the grades above them.

On grade would be quadratic in 9th.

[–] HexadecimalSky@lemmy.world 0 points 7 months ago (2 children)

Yeah....I am american and almost done with my associates degree....and I still haven't learned "quadraitcs" idk, standards are wired

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.

[–] Amir@lemmy.ml 0 points 7 months ago* (last edited 7 months ago)

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 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.

My middle school student worked on them last year

[–] pacmondo@sh.itjust.works 0 points 7 months ago

In senior year at my high school depending on what math track you go in you can be doing AP Calculus

[–] beansbeansbeans@lemmy.world 0 points 7 months ago (1 children)

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.

I guess you can see this earlier but in Europe you cover it in middle school

So fucking real

[–] driving_crooner@lemmy.eco.br 0 points 7 months ago (4 children)

As an actuarie this meme is kinda true but mostly false. I had classes on some advanced maths like ordinary differential equations that have never use on my day to day job. But, the actuarial sciences math in collage was elementary school level of abstraction compared with the real world. There's still a lot of excel tho, but I'm cool and use python (pandas) wherever I can.

[–] null@slrpnk.net 0 points 7 months ago
[–] xpinchx@lemmy.world 0 points 7 months ago

Same here, I still do a lot of complex problem solving and modeling but excel/python handles a lot of the dirty work for me.

I use the college stuff maybe once a month, but still in Excel! You cannot escape the Excel!

The my mentioned "all of it" includes excel :) but nowadays we a bit by bit transition to python

As an engineer I don't get to use any of it very often. I'm always excited when I get to do any actual engineering instead of project management.

Real Math used at work is only for the smart kids

[–] saltesc@lemmy.world 0 points 7 months ago (10 children)

I did advanced mathematics and chose physics as one of my elective subjects in school. Nowadays, I do a lot of work based around analytics and forecasting.

"We need to find the average of this."

"That's easy. I'll do some more advanced stuff to really dial in the accuracy."

"Awesome. What's the timeframe?"

looks at million row dataset "To find the average? Like a month. Some of these numbers are mispelled words... Why are all these blank?"

"Oh, you'll have to read this 45 page document that outlines the default values."

And that's how roffice maths works. Lots and lots of if conditions, query merges, and meetings with other teams trying to understand why they entered in the thing they entered. By the time the data wrangling phase is complete, you give zero fucks about doing more than supplying the average.

[–] MonkeMischief@lemmy.today 0 points 7 months ago (1 children)

Dang, I was really hoping this would be one of those stories that goes like:

"How long will that take?"

"It's a lot of data...like a month?" (But I actually wrote a Python script that compiles and formats it perfectly in like 5 minutes.)

"You're such a hard worker!"

Yup this is every job now. Wrangling numbers. The actual job or calculation could be done in days if less. But dealing with dirty information and playing detective which isnt even part of it is the sink hole of every job right now.

That's software development for you. Why is that weird value there? Because some guy, at some point, had checked for that and somehow it's still relevant.

I know of a system that churns through literally millions of transactions representing millions of Euros every day, and their interface has load bearing typos (because Germans in the 90s were really bad at the Englishs).

I was denied a mathematics education, for real. I can't even do long division, nevermind that squiggly F shit. I thought that stuff was only for astrophysicists.

I want to learn basic maths, but I'm in a 'learned helplessness' mindset where I can't even get through basic sums and equations intended for children (I'm old as fuck now).

I was diagnosed with autism a few years back, which kinda made no sense. I would have expected rainman powers, but numbers just don't jive with my cunt of a brain. Maths is as inscrutable to me as people's faces or social cues.

[–] Ethanol@pawb.social 0 points 7 months ago

don't let yourself get discouraged, math isn't everything ^^

[–] Liz@midwest.social 0 points 7 months ago (2 children)

You might also have discalcula, which is a real but somewhat uncommon thing where you're absolutely shit at math. I have no idea how to get tested for it though.
