Saw a math problem posted on FB that requires the application of this acronym and thousands of people have answered it with many people answering it incorrectly. The funny part is some of the people answering it incorrectly throw out insults to people calling them names or that they need to go back to elementary school.

For those of you not on FB or that haven't seen it, the problem I am referring to is:

6 - 1 X 0 + 2 ÷ 2.

Popular answers commented include 0, 1, 5, 7, and 3.5.

BTW, the correct answer is 7.
 
I'm not a wizard, but how can you argue anything other than 7? Basic middle school algebra, heck, I think we learned order of operations in elementary school. I bet the same people arguing this on facebook are the same ones that shill their supplement scams and body wrap weight loss gimmicks and have cheesy slogans on their wall like "you are beautiful even if a fat ugly whore" and "seize the day by swallowing it".

Many people have commented they used that and got 5. Apparently their Aunt Sally thinks 6-0+1= 5. And apply the rule wrong saying you must add before you subtract. So they turn that into 6-1. Their comments calling others idiots and such are quite comical.

Please excuse my dear aunt Sally.

Multiplication and division are first.
 
And these people getting the wrong answers and insulting people are probably also the parents "fighting" common core. They aren't really sure why and by golly there education was amazing so why change it! The world will always be the same so we should always receive the same education in the same format as our parents!!

Two things: the people getting it wrong don't know basic math skills, period, and common core sucks, it's a scam, IMO. It hasn't been in place long enough to generate enough data to suggest it "works" (though in fairness there are no data to truly demonstrate that it doesn't work either). However, if it doesn't work, we're digging ourselves an even deeper hole WRT STEM education in this country.

Funny thing is some people that got it wrong accused others that got it right of must having learned via common core.

One guy that put 5 said he was a nuclear engineer.

I was thinking it was posted as propoganda to support common core to prove the old way Math was taught didn't work so great either. And with how many people answered incorrectly, it would have helped their case.

That being said : i don't think common core would solve the issue.

Elementary and junior high school were many, many years ago for me. When I first saw the equation I grouped it incorrectly and got 5.

(6-1)(0+2) = 5
2

I appreciate the refresher in order of operations.

Not saying Common Core is good or bad (personally I think they are insignificant- curriculum and teacher quality are way more important than standards) but the facebook "experts" that are on a crusade against common core probably struggle with this basic math problem.

What exactly do you find wrong with common core math? I can't seem to find anyone to give any semblance of an answer when I ask that question.

I'm an engineer, who tutored for 5 years and I really like what I read on the common core website. I also can't stand politics so I'm really not trying to fall on either side of the issue.

I think that it's something new for the sake of something new. The intent should be the bettering of our students, and I do not feel that this is a step forward in terms of educating.

I all for pushing the envelope and embracing new technologies with respect to education and educating. My wife is a bonafide scientist, a professor at a major university, so I realize that the science curriculum, for instance, is ever evolving, but what I can't see is why the teaching of fundamental mathematical principles needs to be changed, and more specifically, how the common core methodology improves things. The fact that our country lags behind many other developed nations in terms of STEM is not because we didn't have common core, but it's due to other systemic deficiencies in the educational system in this country. Further, by the time we can actually empirically determine IF the common core helps, we may very well be even worse off. There's a real risk with paradigm-shifting..."well crap, that didn't work out like we hoped."

At last that's what I think. :)

One clarification: I'm less concerned about the reading aspect. Developing new methods for teaching kids to read somehow doesn't raise my hackles like the math stuff. :)

What about them isn't a step forward?

I would really like for someone, anyone, to go to the common core website and look at the math standards and tell me what the big problem is. Again, I've read through them (I'm sure I didn't read through every standard) and I can't find a single thing wrong. Has anyone actually read them?

Here are a few excerpts:

Understand that integers can be divided, provided that the divisor is
not zero, and every quotient of integers (with non-zero divisor) is a
rational number. If p and q are integers, then -(p/q) = (-p)/q = p/(-q). Interpret quotients of rational numbers by describing real-world contexts.


Nothing extreme about that.

Here is the common core standards on functions:

Understand that a function from one set (called
the domain) to another set (called the range) assigns to each element of
the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

http://www.corestandards.org/Math/Content/HSF/IF/A/2/
Use
function notation, evaluate functions for inputs in their domains, and
interpret statements that use function notation in terms of a context.

Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers. For example, the Fibonacci sequence is defined recursively by f(0) = f(1) = 1, f(n+1) = f(n) + f(n-1) for n ≥ 1


Again, those are not extreme. In fact, I'm guessing I could put that definition on some silly graphic and claim that's what should be taught in school instead of common core and people would eat it up.

What exactly was wrong with the "old way"? There is nothing wrong with the technical description that you posted, it's completely correct, there's no disputing that. What, though, is the motivation for fundamentally changing how math has been taught? You can't yet convince me that common core leads to better outcomes, and there won't be data for a long time to indicate, in either direction, what the effect of the new standards is.

Our students are lagging, thus no child left behind, thus something new was needed, and thus common core and new standards. I don't think that this will improve things...but I don't know what will.

What exactly has been fundamentally changed? Again, I can't find anything that suggests some fundamental shift in how we teach math. In fact, the common core website doesn't even address how students should be taught-


What guidance do the Common Core State Standards provide to teachers?
The Common Core State Standards are a clear set of shared goals and expectations for the knowledge and skills students need in English language arts and mathematics at each grade level so they can be prepared to succeed in college, career, and life. The standards establish what students need to learn, but they do not dictate how teachers should teach. Teachers will devise their own lesson plans and curriculum, and tailor their instruction to the individual needs of the students in their classrooms.

The website might not show any fundamental change, however I can tell you from first hand experience of watching my wife teach 1st grade, that the materials used in class to teach basic arithmetic are apples and diodes different.

My biggest problem with Common Core isn't actually common core itself, but the fact that there seems to be a "let's change s*** for the sake of changing it" mentality with education these days. As I said, my wife is a 1st grade teacher and has been teaching for 10 years. In that time she has had 4 or 5 different reading programs to follow and 3 or 4 math/science programs. Each with its own goal and/or aim. Now some of that is coming from the state level and not federal, but it is hard for a teacher to be effective if the landscape is consistently shifting under their feet.

Elementary and junior high school were many, many years ago for me. When I first saw the equation I grouped it incorrectly and got 5.

(6-1)(0+2) = 5
2

I appreciate the refresher in order of operations.


Order of Ops is a step concept as well as a flow concept. So not only are you supposed to do Mult/Div before Add/Subt, you also only do those on the same level first and then work left to right (normal reading direction). So really PEDMAS should be:

Parentheses

Exponent

Mult/Div

Add/Subt

So with the equation presented: 6 - 1 x 0 + 2 / 2 There are no parentheses or exponent (this is part of where you got it wrong DFS, by putting something in there that wasn't). So 1 x0 = 0, and 2 / 2 = 1 (Same level of operation, proceeding left to right) That leaves us with: 6 - 0 + 1. Flowing left to right, the answer is 7 as was said in the OP
 
My biggest complaint with common core was that I didn't understand it. I think that's where most parents are. Once I took time to understand not only how to use it, but why it was being taught that way, I have no issues with it. There were a lot of flaws in the old algorithm methods we were taught with as well that we've simply ignored.

In my son's class they actually teach both ways. He is learning in second grade the common core method first as it generally explains why the math works as the algorithm methods do not, and then learning how to use the algorithms as well. I can't complain with that method at all.

That sounds reasonable, I agree with this in general. I think that part of "not understanding it" probably applies to the teachers as much as it does the parents (and that is understandable as well).

But does this improve outcomes? My concern is that it is a waste of time. If BOTH approaches are taught, what is given up? Can our students generally lack of mastery of basic mathematical skills be (heavily) attributable to not being exposed to "common core methods"?

Obviously, given my posts, I am skeptical, but I DO want the education system improved (my son is in kindergarten), and by some combination of school AND what my wife and I teach him, he will succeed, I am certain. Maybe it's just that I don't fully understand/appreciate the "new" approaches, and as such, I worry that they represent time and resources lost (something new for something new's sake).

It will be many years before there is quantifiable evidence about these approaches. I hope they are a smashing success, of course, but I have my doubts...but I also don't know what can be done to improve things.

LT, refer back a few posts. It isn't that addition should be done before subtraction, they are the same level of operation, thus you work them in the order they appear, left to right.

Your "A" step is screwd up.

You were in good shape up to the "D" step.

6 - 0 + 1 = 7.

Not sure why added parenthesis (that's the P in PEMDAS) to group up the (0 + 1) to be a subtraction.

Thanks, that's it.
 
Yes. I guess it really should be PE(MD)(AS).As it really could be PEMDSA, PEDMAS or PEDMSA.


P - Parentheses first
E - Exponents (ie Powers and Square Roots, etc.)
MD - Multiplication and Division (left-to-right)
AS - Addition and Subtraction (left-to-right)

Divide and Multiply rank equally (and go left to right).
Add and Subtract rank equally (and go left to right)
