So she's bragging about being retarded or what?

>>10751262
Perhaps if you weren't a Twitter THOT, you might have more pressing problems than whether Deyvon in Starbucks thinks your Aviators are cute or not.

>>10751262
she obviously doesn't work in STEM

>>10751289
But that doesn't answer his question. The kids that aren't mathematically inclined and are almost certainly not going to go into mathematics have no use for it.

>>10751262
she's unironically correct
education is a mass-produced service for people incapable of efficiently teaching themselves about precisely what they want to learn and no amount of seething cope will ever justify you wasting your time for a degree where only 10% of your entire education will ever come to actual practical use while everything else was an inflated curriculum so they could justify charging you those abnormal sums of money for such long periods of time because teaching you only what you truly needed would be a fraction of their profits and time spent squeezing them off of you
btw don't even bother replying to me I genuinely don't give a fuck about your cope lmao enjoy your wasted years

>>10751333
which is why we need to put an end to compulsory education and stop wasting money on educating twerkers and sportsballers

>>10751262

>>10751267
Lacking knowledge doesn't make you retarded.
Its useless to teach low IQ people and even midwits these skills. Worst case scenario they worm themselves into positions the do not deserve and depress overall wages, as well as increases the cost of education. We should go back to teaching the Three R's, and some basic life skills for most people. End high school at about age 15. That's old enough to start working. High IQ people can start college then if they want. We need to get rid of this idea of universal higher education whenever higher faculties and higher intelligences are not universal.

>>10751262

I use linear algebra when i shop for good deals.
My drug dealer needed to know linear algebra and metric system conversions (1g ~ $20, 1/8oz ~ $60, 1/4oz ~ $100, 1oz ~ $300).
Whether buying or selling, basic linear algebra is useful.

>>10751356
I agree.
Covering anything beyond the basics should serve the purpose of filtering out the low iq people.

>>10751321
So? It's not like you can sort out in junior high school which kids will go into STEM and which won't. They all receive the same education.

It does answer his question.

Bullshit. My grandpa's not even college-educated and he uses algebra doing basic tasks. Like building a shower, or a deck. If you want to build anything and have it not be shit, you use math.

Imagine bragging that nothing you do is complicated enough to involve FUCKING LINES

>>10751321

Other than that, math teaches symbolic problem solving that you don't get in English or History. Kids might never have to use y=mx+b but they sure as hell need to be able to understand the concept of variables and constants, equivalency and computation, and being able to visually interpret something as simple as a string of characters

>>10751321
>>10751289
Wrong

The point of algebra in high school is not to know it but to learn to learn something like algebra. It increases general problem solving skills. And then its also convenient that the knowledge itself is useful for those who have a need for it, so they get a head start thanks to algebra

>>10751984
Fallacies are the most fucking retarded argument killer ever devised. Maybe if everyone supporting an argument is a sub 90 IQ faggot retard, it's a SHITTY argument

How about curiosity? How about wanting to understand more than you do now? Knowledge is intrinsically valuable both in the discovery and the knowing.

Why do you need a compulsory class to learn something you want to learn?

The same people who complain about stem being useless are also the same retards who think humanities are also useless. Fact is they're anti-intellectual no matter the field. The only aspirations people like these have are eating, shitting, sleeping, and breeding the next generation of retards.

She's right you know. Once you have a rudimentary level of math, it should be switched to finances. God knows people need to understand their finances correctly. Savings/coupons/bulk orders/etc are all done on daily basis for many people.

>>10751333
That's not really what this is about. You could also extend her mentality to all the other practical aspects of human existence like starting a fire, knowing which way is West based on sun orientation, or knowing how to track animals or grow plants. There are people who don't have to learn or know much of anything because their parents and/or society provides for them. All that boring Mathematics shit can be done by Indian and Chinese people writing software and building all the hardware she uses. She's just being an edgy cunt lashing out at the society that provided her with an overly privileged lifestyle.

A whole bunch of boomer nonsense. Notice how it's nothing about "how to acquire food" because all the illegal immigrants are expected to do that for us.

Derivative refers to change, so slope is actually dy/dx, correct?

>>10753055
There's no way your average American high school student will grasp that concept.

>>10753055
The derivative of the function f(x)=mx+c is m, so it's a particual case.The definition of derivative rests on this notion which is actually more primitive.

>>10753057
I know, I'm asking for my own sake because I've been away from math for way too long and I want to know if I remember these concepts correctly.
>>10753059
I know that m is the derivative of f(x)=mx+c, I am just asking if I remember correctly that m could be defined as dy/dx

>>10753067
>I am just asking if I remember correctly that m could be defined as dy/dx
Not really. It's not a wrong statement but the definition of the derivative uses the definition of the slope of a line. Well, the definition is the slope of some line. It gives the slope "m" of the tangent line of a curve at a particular point. So you need this notion already to define dy/dx.

>>10752862

>>10753074
So slope could be defined as dy/dx (not vise versa), whereas dy/dx could be defined as slope of the tangent, correct?
I should know this, I used to be really good at math, I just have been away from it way too long. Thanks.

>>10753100

That is such linear thinking.. I can't even ....

>>10753102

yes. All slopes are dy/dx where defined. Not all dy/dx are slopes except of the tangent line at that point on a curve.

Do things like factoring, simplifying nested fractions or simplifying radicals have a real-world application, outside of math classes? If you were programming and you ask the computer to manipulate 27^1/3 instead of just a 3.....does the computer use extra resources to return an answer or would it even matter?

Math is expected to actually be used in class instead of just memorized. It's complained about because you need to be able to understand and apply something sort of abstract, not just regurgitate facts, in high school level classes. My high school biology class didn't ask us to come up with experiments, our labs were just us following instructions and taking the notes we were expected to take. But in any level of math you actually have to work out a path to the answers for yourself.

so what are you doing now?

>>10753571
You might be right. Ijust looked at her tweets and it seems that she's just too dim to realize how teaching algebra can be useful.

>>10751262
In my opinion education is flawed in the sense that it is meaningless insofar as knowledge goes. The reason for this is that the point of school is to get a degree obviously, but that is irrelevant to the learning goals; however, the learning goals are too numerous to be meaningful. Therefore, I would propose instead to make something more project-oriented, but in such a way that it doesn't lead just to outsourcing knowledge from what's already known in an engineering sort of way, but instead we should think of this in such a way that the scientific fashion of doing things is also included: that is through the discovery of new knowledge and not just reusing it

>>10752265
literally this

>>10753232
Can anyone expand on this? Now I want to know as well. if you have code where you input something with a radicand in the denominator of a fraction, does the computer really care? It seems like some math skills are just to pass on the learning so people aren't totally reliant on something that someone already programmed the effort out of. Or so if we get emp'd we don't lose all the math knowledge.

This. It's just a coping method. They were able to write some nonsensical "analytical" drivel to pass their history and English classes, so it doesn't matter to them. But they failed math and science so those subjects must be worthless.
Not saying that humanities are inherently worse or easier, btw. Writing a competent essay is fucking hard and requires a lot of practice, like any craft. But at the K-12 level teachers don't give a fuck, so humanities teachers don't read anything and give everyone B's, whereas math teachers just look for the matching numbers on the answer key.

just because a definition is inspired by one thing, doesn't mean applications of that definition need to be interpreted in the original setting. all linearity says is, given a vectorspace with vectors u and v and scalars a and b, define a function T that has the following property.

We gotta reform the edajamakation system. No more can it be a factory model. No more can we have 8 - 10 hours 5 days a week for fucking 5-10 year olds. Ease them into this shit damn it. Start with teaching things like;
>Chess, sudoku, any mental puzzle games
>Studying techniches
>Health, nutrition, proper stretching, and fitness
>The history of science
And ease kids into it. Start with, when they're like fucking 5, maybe 4 hours a day, three days a week. Then 7 hours 4 times a week. THEN full frontal full on job 9 hour days 5 times a week.

Out of all the lessons I had at GCSE level, the one that the fewest people took seriously (i.e. none of them) was PSE, which is exactly that kind of thing.

AHAHAHAHAHAHAHAHAHAHAHAHAHA
When do Americans learn the quadratic equation? Because in the UK everyone doing GCSE Maths Higher (so everyone who's not a retard) learns it

I learned about curve fitting in a physics lab and then got intrested in it. This is just a silly comic about it dude chill out. I posted it because it's a major application of mx+b

You would be surprised how many people "learner" quadratic formula in school and just pnp'ed (I was one of these people)
