Can bright lolis really do calculus in Japanese elementary school? No wonder America is falling behind in education.

Shit is piss, nigga.

Normally, yes. In the 50's in France 10 year old girls was all able to do it. That + speaking perfect german. Also, all girl schools. Good old times.

>common core math

>>

>>121323243

Schooling 100 years ago was so much better.

>>121323296

What the fuck is common core?

>>

>>121323016

she aint revolving shit. she's obviously integrating the areas of the circles

>>

Why isn't there any "cute girls doing advanced math" anime?

>>

>>121323500

because anime is not for nerds

>>

>>121323500

sheeeyit is that an induction problem

>>

>>121323561

You're lying. This isn't real.

>>

>>121323561

I still don't get how this shit is supposed to work.

>>

>>121323568

first thing that comes to mind is little fermat

>>

>>121323561

Someone explain to me what the fuck is going on here.

>>

>>121323606

>>121323669

He added simple numbers that he can handle until 32. Then he added all those simple numbers up.

>>

>>121323561

What the fuck is this?

>>

>>121323606

>>121323561

>>121323669

It's taking 12 and adding up to 32.

>>

>>121322953

I want my future children and grandchildren to be doing calc 2 by age 10

>>

>>121323705

Dear lord.

Why?

>>

>>121323689

>>121323705

That's such a retardedly ass backwards way to do a simple problem. The old way is far simpler and quicker.

>>

>>121323609

Didn't Euler make a more general formula of feman using the phi function?

something like

a^phi(m) = 1 in Z(m) if and only if a and m is relativly prime?

Holy fuck I still remember this shit. Unless I'm way off track.

>>

>>121323561

>>121323595

>>121323606

Is...Is this for real? People are pretty mad around here with the new ''reform'', but its nowhere near this. No wonder americlaps hate this common core shit

>>

>>121322953

I don't get why they leave calculus for so long, It was only introduced to me at 16 (in the UK). They should really start with the easy shit sooner.

>>

People make a big deal out of Common Core Math, but all it's really doing is trying to teach idiots how smart people do math. Which is obviously not gonna work.

A better example would be 8+5=13. Some people have trouble seeing this, like I did way back in kindergarten. So I just broke it up into 3+5+5=13, which is easier since 5+5 comes out as 10 insanely fast in my mind and then I just tack on the 3.

Written out on paper, it's obviously gonna look dumb. But these weird operations come out super fast in the mind. CC just tries to make a habit out of making those weird operations so they can be applied to more complex problems.

I'm not advocating it at all, as I said before this is obviously gonna fail.

>>

>>121323830

>People are pretty mad around here with the new ''reform''

Poland?

>>

>>121323561

This is an example of a naive way of implementing subtraction with using negate and minus operators.

>>

>>121323843

The idea is that you have to build the fundamentals first, so you have to teach algebra, then geometry, then trigonometry or calculus.

>>

>>121323873

Well I said new but it's actually like 10 years old , province of QuÃ©bec, Canada. We use a different system than the rest of Canada for highschool etc, but I'm unsure about ''the way we learn''

>>

>>121323965

>you have to build the fundamentals first

I wasn't taught the fundamentals (the axioms of ZFC) before university.

>>

>>121323561

I like how this immediately breaks down for big numbers

>>

There's more of this shit?

>>

>>121323965

Yeah, but why not start with that earlier. Basic calc (I'm talking straight forward differentiation and integration along the lines of f(x) = x^n) is as easy as algebra, the concepts are not even difficult.

>>

Here in America the standards have been lowered incredibly far, to the point where teachers are forced to pass a certain amount of students or they lose their job.

This is also the reason why most jobs require college now, because modern college is the equivalent of high-school 60 years ago.

This shit is ruining America

>>

>>121324103

It's as easy as algebra if all you're teaching students to do is naively carry out the process without understanding what they're doing, but I don't consider that a useful way to learn.

>>

>>121323827

yes, but you don't need it, you only need the binomial theorem

(1+ n)^p = n^p + p n^(p-1) + (p choose 2) n^(p-2) +... + (p choose p-2) n ^2 + p n + 1

you subtract the summands that aren't divisible by p, and the other are divisible by p since p is prime and remains as a factor in each binomial coefficient.

>>

>>121323561

No one would ever do the bottom one unless you force them to.

>>

>>121324226

What is so difficult about the concept?

>>

>>121324226

>carry out the process without understanding what they're doing

This is what schools teach, and it's why people in general are fucking retarded and hate school

>>

>>121324193

what's the problem? is it frustrating to not earn anything until your are in your 20's?

>>

>>121324016

>10 years old

That's quite old, but the reforms are usually considered shit by most people, the reform in Poland was really shit because they had redesigned the high-school certificate exam, but they didn't give any information about how is it going to look like until you were in the second year (the law says that they should reveal it while you're in your first year)

>>

Fuck man, I'm on vacations, I'm not here to see more math.

>>

>>121324283

you realize that a lot, and I mean atleast 80% will never need to or want to understand maths.

not everyone is smart, you might have to accept this

>>

>>121324075~~LITTLE~~~~WHITE~~~~DICKS~~

>>

>>121324103

It's really fucking pointless to teach them that when they could do nothing beyond the absolute most basic problems of calculus.

Like REALLY pointless. Have you taken a physics course without taking calc? It's like that, fundamentally a waste of time.

>>

>>121324331

>80% will never need to or want to understand maths

The only thing people need to do is dying.

>>

>>121324376

> Have you taken a physics course without taking calc?

Don't fucking remind me, but you have to start somewhere.

>>

>>121324290

>why is it a problem that we are lowering the standards and creating a nation of retards

>>121324331

supporting a ridged and standardized form of education is harmful to the future of any society, saying "some people aren't smart" is nothing more than a deflection from the actual issue

>>

>>121322953

Miyu was autistic though

>>

>>121322953

actually, that looks like Trigonometry.

>>

>>121324469

>integrals

>trigonometry

>>

thats what happens when you have "no student left behind" policies.

everyone in every subject is taught as if they are dumb niggers.

the only way to get ahead is to study on your own.

>>

>>121324469

She's clearly integrating to find the volume of the cone.

>>

>>121324469

>Trigonometry

What?

>>

>>121324278

Nothing, but the way schools teach STEM subjects is fucktarded and doesn't help students understand how anything works, so as soon as they encounter a problem that can't be solved with a memorised process most of them can't cope.

All school level maths in western countries teaches students to do is solve problems that they have been shown how to solve.

>>

>>121324469

She's using calculus to solve a geometry/trig problem.

>>

>>121324331

See this is why I hate common core currently. The simple fact of the matter is that schools currently work on the assumption that all students are created equal and that they all have the same needs upon graduation, which is just flat out wrong and naive, and common core exasperates this. What we should be doing with schools is giving everyone a solid foundation of math, science, and language in primary, then using secondary school to figure out what the kids are good at, what they think they're good at, and what they want to do after school, and tailor their entire secondary schooling experience after those criteria.

>>

>>121324376

>Have you taken a physics course without taking calc?

I took grade 11 and 12 physics before calc. Looking back shit would've made so much more sense.

>>

>maths

>s

Fucking yuros

>>121324356~~BOOOOOOOOO GET OUT OF TOWN~~

>>

>>121324469

>Trigonometry

She has the height and radius given, and she needs to find the volume, where do you see trigonometry?

>>

>>121323561

It's actually pretty neat once you start with modulo operations.

>>

>m/a/th thread~~Stop reminding me that I'm a fucking idiot.~~

>>

>>121324558

A maths teacher of mine once said that if you insist on using a crane to pick up a screwdriver you might as well use the biggest crane you can find.

>>

>>121323561

I can understand why you would use this kind of thinking to teach kids that they can add something together one bit at the time without changing the result. I can also see it being useful as a trick to make mental addition easier.

But why would you teach kids this as a way to tackle the problem in writing. Is the new problem that the old problem is being translated to actually easier?

>>

>>121324625

no difficult subject yet.~~but probably soon.~~

>>

>>121324625

Its okay anon, not all of us here are good at math. I was the product of a big city awful public school system. I have a math teacher in high school who didn't speak English.

>>

>>121322953

Was this on the manga? I really don't see why would Shirou or Kerry would bother in teaching her this stuff in the middle of an apocalyptic world.

>>

>>121324625

Don't worry, you're not alone. I have no idea what the fuck people are talking about in these kinds of threads but I find them fascinating regardless.

>>

I'm surprised no one has blamed the jews for these, like, 2 instances of retards trying to be intellectuals by fucking with math

>>

I fucking wish I'd done maths at uni, instead I did physics and everyone is dumb as shit ;_;

>>

>>121324773

did you already get a degree? it might not be too late to switch, even some people who got a master/something equivalent in physics did their phd in mathematics.

>>

>>121324625

I'm no good at math either, yet I'm programming a game just for fun.

I'm probably gonna screw with some vectors calculation...

Oh well.

>>

>>121324706

Kerry didn't know her in that world, she was the real sister of Emya that died during the fourth GW thing.

Also it was, not exactly this, but something similar

>>

>>121324821

I'm second year on a four year course, I think I'm too far in.

>>

>>121324773

>instead I did physics and everyone is dumb as shit ;_;

Look at the students on a non stem subject course, you haven't seen anything yet.

fuck this shit I didnt sign up for numbers and shit

>>121323561

De goyim must be kidding. Right?

>>

>>121323799

>>121323823

when talking about this to the oldest generations (70 & up) this apparently resembles a method employed back before the industrial revolution.

Henry Fords thoughts on education focused on simple, efficient, and just enough to be useful in the business world. and he had the influence to change the educational system to fit his views. that was the method we all learned growing up since the industrial revolution.

this new common core approach to math seems to hearken back to what we had before that.

>>

>>121323561

It's funny how it takes longer and is less intuitive than the "old" way.

Tell me again WHY is this a thing?

>>

Euros are stupid. They can speak more than one language, but that's not intelligence since a child's capacity for language is completely infinite before the age of 7. In chemistry or physics - the shit that actually MATTERS - they have about the same level of education as a cocker spaniel.

Ditto for Nips. Do you realize a 30 is passing over there? A FUCKING 30?

>>

>>121323561

The purpose of common core was to expose students to abstract ideas early on to escape "drilling" and repetitive calculations.

In reality all it did was create children that know set theory but can't do arithmetic (future engineers).

>>

>>121324674

>Is the new problem that the old problem is being translated to actually easier?

I don't think its supposed to be about ease, its about ensuring kids have a better grasp of number theory so they don't grow up to be fucktarded adults.

>>

>>121324773

nigga STEM is about the smartest you are going to get. Math wont be much better and any alpha study will be abhorrent.

And then you dont even consider the bulk who cant even handle that level

>>

>>121324842

>Kerry didn't know her in that world

We don't know that, but we do know that the Shirou from Miyu's world was adopted by Kerry and I don't see why would he just adopt Shirou and not Miyu.

>>

You have no idea how hardcore private schools can get. Especially ones in Germany that's preparing entrants to research universities.

Euclid was a geometer, so no.
