What does /pol/ think of common core?

Designed to confuse and to make education relative/arguable to better manipulate how different demographics are marked. IE a white male can be penalised for not showing emotions in their math solution, but a black girl can get full marks for a blatantly wrong answer.

>>133911705
You multiply the 2*2 which is 4. You then multiply the 5*4, which is 20, then divide 20 by 20, which is 1

>>133911705

treating the equation as a fraction as opposed to seeing "/" as just "divided by".

I thought "the old way" would get you 16...

>>133911931
No you don't.... This is not how order of operations work in the slightest to simplify it looks like this.

20/5 (2 * 2)
20/5 * 4

then simply work left to right because multiplication and division hold the same place in operation.
4 * 4 = 16

>>133911931
>wat is pedmas
Answer is 16, I haven't read anywhere that 4(4) comes before 5/4. Just because you don't have the * between the 4 and parenthesis, it doesn't mean it magically becomes of higher priority. If you want it to be of higher priority, you use parenthesis, that's what they are for. Another method would be to rewrite it as a fraction, with 5(2*2) being on the denominator. A missing * doesn't mean jack shit. Answer is and always will be 16.

>>133911226

The whole "addition to do subtraction" is honestly how I do it.

Say it's something like 433-198. I estimate what I need to add to 198 to get to 433. I start with 200 (which makes 398), then add 2 (to get 400), then add 33. My answer is 200+2+33 = 235.

Multiplication and division are the same operation.

So I guess this thread has been derailed due to retards who can't do literal 5th grade arithmetic, but I'll toss this in anyway.

Most people who are against Common Core fall into two categories, from my observations:

1. The ones who approach it from a strictly anti-federalist point of view. They don't like the idea of even implied federal unification of standards across states.

2. Morons who think images like OP's are accurate, or who think curriculum materials put together by corporations are the same as the Common Core standards.

Category 1 I'm fine with, though I repectfully disagree with their stance (every educational system in the developed world EXCEPT the US has national, centralized education, and the same people who complain about the state of education in the US for some reason don't understand the irony of lamenting how we're "losing" to countries like China)

Category 2 is simply morons who are easily riled up and don't spend 5 minutes checking basic facts.

I know a fuckload about this so feel free to come at me bros.

>>133915360
>your future relies on 1 test you take when you are 18. Fuck up, and you die lonely

That last thing has nothing to do with tests or the education system and everything to do with a culture that falsely believes everyone is capable of and should pursue higher education. There are plenty of decent careers that do not require anything besides MAYBE a high school diploma, and probably you could get into them without one as long as you put in some effort.

That problem boils down to a÷b(c) in which you ask yourself if you follow the mathmatical convention of juxtaposition of multiplacation set by the ams, you would pair b and c together as one term before dividing. Its why 9x2 ÷3x is equal to 3x and not 3x3. Your calculators for the most part most likley do not follow this convention however, that does not mean it does not exist.

>>133912714
You idiot

It's PE(MD)(AS)

MD are done before AS, but when you can do one or the other for each group its left to right

>>133911226
That's a very shittily written equation

The thing is, does anyone actually write that like that? Just put (20*(2*2))/5, what is even the point of writing the (2*2) with the 5 if it's multiplying the 20 "(20/5)*((2*2)/1)"???

This is dumb and trash level, wake up america.

>>133915203
>don't understand the irony of lamenting how we're "losing" to countries like China
The reason why China and Asia in general has great education is because of culture. Parents are actively involved in their kids' education and even the poorest kids in South Korea and Japan go to private tutoring academies. Their public schools are actually sub-par compared to those academies. Kids sit at their desks and just take tests. The real studying happens outside the classroom.

US education is brought down by niggers who aren't even genetically human and are incapable of reason. If China had 13% black population its academic achievement would be bad too.

I agree with the culture part, although I think your rhetoric about blacks is unfounded. However, China is simply the first example that popped into my mind. Choose literally any country that scores higher on PISA or whatever your favorite test is and they will have a national education system. The majority of said countries follow progressive education philosophies that people here mock as "Common Core" (which doesn't make sense because CC is a set of standards) or New Math etc.

Again, it's all about ignorance. I just saw someone in the other education thread claim a normal elementary school has 40 fucking students in it. Who knows what other gibberish that poor bastard spews to his conservacuck friends.

>>133917139
Writing 3xa is different than writtimg 3a depending on the mathmatical conventions your taught. In america, if i was told to solve 9x^2 ÷ 3x most people would write it as a fraction and cross out the 9 and 3 to make 3, and the x squared and x to make x giving you 3x as the answer. However, followimg pemdas strictly you would first multiply 9 by x sq. Then divide 9xsq. By 3 to get 3 then lastly multiply 3xsq by x to get 3x cubed. So they are not the same.
