This article is mostly right though. Not everyone needs algebra. The biggest lie in America is that everyone needs to graduate from college and that college degrees = better jobs. You don't need algebra to be a plumber, taxi driver, or journalist, actor, or politician.
The solution shouldn't be come up with bullshit placeholder math classes though. Kids should be allowed to drop out and there shouldn't be a stigma in our culture associated with dropping out / not finishing high school. Not everyone needs to have a college degree.
>>7962580
People think they don't use algebra daily but all algebra is essentially is just arithmetic where the manipulated quantities can take on a discrete set of values. We do this math without thinking about it. For example, with money, especially for poorer people, you are often calculating what you can spend/save while still having enough left for necessities. This is an algebraic equation/inequality, you know how much you have and the minimum remainder you need, your spendable money is a variable. You don't think about it like that, but it is.
People just have a hard time translating that arithmetic to variables and unfortunately most people prefer to give up when they encounter obstacles.
>>7962586
They're insane. All of these nutjobs who've taken over the educational system are batshit insane.
Also, there's a huge demographics shift happening right now and vast majority of new students simply don't have the genes to pass the material and high-standards anymore.
That's why you see all this "new math"/"common core" bullshit popping up. They're trying to hide the fact that America's getting dumber. A lot dumber.
>>7962594
>all algebra is essentially is just arithmetic where the manipulated quantities can take on a discrete set of values

I made a minor mistake, a variable can also take on a continuous set of values as well. Small but important correction.

This logic..........
1/5 students cannot meet current educational standards.
Solution: Lower standards
How exactly does this help students. 1/5 of students will still have the same substandard education, but now there is a chance that some of the other 4/5 of students will not take the class and thus also receive a substandard education.
Plus you get that added bonus that the students that did go the extra mile and take algebra will now be stuck with a degree that employers know is watered down, as I have never known an employer to request my transcripts. (college or otherwise)
Way to absolutely screw the next generation. Cheers

>Many U.S. educators, including the architects of the Common Core standards, disagree, saying math just needs to be taught more effectively
I think they are hitting on the main issue here, that teachers suck, only care about their jobs, and couldn't care less about students. But then again, if I had to deal with a bunch of faggot students that didn't want to be there or cared, I'd be that way too.

On top of that, the teachers usually aren't proficient to really inspire students about the next level of material, exciting applications, or give meaningful further exercises/projects.
If you look at virtually any college/pre-college metric measuring performance (GRE scores, ACT scores, GPA/honors recognition, research, etc.), education majors (those likely to teach middle to high school) are almost always at the very bottom.
The honest truth is education attracts the lowest-tier of academics or achievers in most cases--or perhaps it repels those who succeed in their fields.

For whole exponents you can just write both out as a products then use the definitions if a^b

Trade work needs algebra actually. I am a hobbyist buliding a drone and I use shitloads of algebra and trigonometry so I imagine carpentry is the same. How the fuck am I supposed to build trusses if I can't rearrange Pythagoras?
What needs to happen is that pure maths needs to be kicked from the curriculum. Instead of boring kids to death with "here's a list of equations, solve them" why not have them build a table and solve for the unknown lengths along the way? I did terribly in maths (E grades at GCSE) at school purely because I thought it was a complete and utter waste of time. It was only when I learned that you could use trigonometry to measure the distance across a river without crossing it that I started to engage and I took A level maths and got an A. Even in History class, another subject frequently called useless you at least got the odd field trip and maybe the teacher dressed up as Hitler, it's good fun compared to Maths where it's "solve these equations for no fucking reason"
>>7962613
Throwing the 1/5 into the trash won't make the problem go away. They will come back as criminals and welfare claimants. In the UK there is no "you passed high school" rather an informal benchmark that you are considered to have passed if you pass at least five of the eleven GCSEs that you do and a pass is set at 60%. Nationally only about 60% of kids make this benchmark even though it's pretty damn low by /sci/ standards and when you say that the five must consist of English, maths and science it drops right down to 40%. If 60% of the country effectively did not pass high school then the system is clearly broken.
However you're right that lowering the bar isn't the answer because I knew the people who flunked and they would never have passed no matter how low the bar. Either make teaching more engaging through what I said earlier about having maths students build tables instead of just solving a list of equations or accept that half the population just isn't academic and provide other routes. Luckily in my country the people who flopped GCSE were allowed to dump mainstream school at 16 and learn music or hairdressing at a more laid back college instead. Now they do quite well in their jobs painting nails or whatever.

Or by induction

It has nothing to do with the difficulty of Algebra, its that its fucking waste of time and worthless for majority of people. Most jobs only require elementary math knowledge.
If america is ashamed of its graduation rates in the developed world, does that mean all developed countries teach roughly the same shit up to 18? And if america can do without algebra, are they saying the rest of the developed world has fat and gristle on their curriculi?
>>7962994
Also, the reason it's more difficult is indeed that the average college applicant has become less educated/gifted in that time. This is much less for dysgenic reasons than it is because the pool of applicants has expanded beyond the aristocracy.

I would have said it's because the associativity of multiplication of the reals. Generally in this situation we assume they are talking about real numbers.
x^3 = (x*x*x)
x^2=(x*x)
(x^3)*(x^2)=(x*x*x)(x*x)
=(x*x*x*x*x)
=x^5

I studied Calculus 2 fully and just a bit Calculus 3 in high school and I went to a pretty average high school (I'm not american). What math do you guys study in hs?

I make 6 figures a year as a software engineer. Maybe that doesn't count as working, but I don't see how this affects my conclusion that most people don't need algebra in their day to day lives.
In fact I would say my theoretical math degree is completely useless in my work. Those algebraic topology classes aren't really doing me much good these days (inb4 some douchebag who's never built real software before talks about category theory/homological algebra and Haskell)
I just would like to point out that in my school system, we didn't learn what a quadratic function or anything to do with "x^2" until sophomore year. (I went 2 years ahead but its still insane that your average teenager didn't learn what this is until their second year of highschool)

It's true. Basically, it boils down to demography. Whites are already a minority in schools and since they had the highest scores, the population as a whole is being dumbed down.
This is why there's a constant pressure to "reform" testing and to "reform" math. All these reformations basically come down to "make it easier so that all these non-white kids can pass high school".
>>7963245
>Fluoridated water lowers IQ.
Not in the quantities that you get from drinking tap water every day. The effect, even if it's statistically significant, is very small. Dumbing down in this case refers to demography.

Is this supposed to be hard? It's 8 basic algebra questions and 1 simple proof.
Eighteen-year-old Isaiah Aristy took the algebra Regents test twice and failed it both times.
Aristy, now a freshman at the Borough of Manhattan Community College who is hoping for a career in law enforcement, said he was good at math until he hit algebra.
"When it came to x and y and graphing, that's when I started dropping, and it made me feel low," he said. "But we don't need to learn what x and y is. When in life are we going to write on paper, 'X and y needs to be this?'"

My father went to school in a time where teachers were still allowed to hit the children (at least the fingers and stuff) and he learned the greece language, hebrew, latin, english AND he finished high school with maths as his core subject.

a^{w}=(\prod_{i=1}^{u}a^{1})*(\prod_{i=1}^{v}a^{1}) \Rightarrow w=(\sum_{i=1}^{u}1)+(\sum_{i=1}^{v}1)\Rightarrow a^{w}=a^{u+v}[/eqn]

What is there to explain?
You can write [math] a^u [/math] as a product of [math] a^1 [/math], this means that the number of [math] a^1 [/math] you multiply is equal to u.
If this assumption is true, then the following lines must be true as well, I have no idea on how to prove that particular assumption and I don't really care for it enough either.
>>7967456
>[math]a^u[/math] is the product of [math]a[/math] u times. If we were to multiply this by a, we would have the product of [math]a[/math] u+1 times which is [math]a^{u+1}[/math]. A proof by induction using the associative property of products will give the result for the product of [math]a^u[/math] with [math]a^k[/math] for any integer k.

you're not saying that. no one knows what the fuck you're saying. it might be "obvious" in your mind, but the idea of basic algebra exercises like this is forcing you to think why "obvious" things work.

I had a nutcase for a teacher that would give about 30 problems a night in factoring, completing the square, complex conjugates, etc. Then the class was spent switching assignemnts with someone and grading it. Rinse, repeat for 180 days.
I got a C in it mostly because I didn't follow directions and couldn't wrap my head around the material when I was so worried about her bullshit rules about tedious formatting. it hurt my math experience till i retaught myself algebra and precalc after I graduated.
