Through all that blathering I understood PEMDAS he did para first, (OK) no exponent, so according to that acronym multiplication is next and unless I missed something, he did division. I understood you should follow the M & D & S left to right, meaning that was the order they were done, not laid out. With how I followed (finally cutting through the mustard) the acronym the answer of negative 1 was right.
It just so happens my grand daughter is learning PEMDAS in school right now but what surprises me is that they’re not teaching the left to right as of yet. I guess it’s a one step at a time thing lol.
@@thenetsurferboy I disagree, and if you listen to this teacher he will tell you the same thing. There are times when you have to make a decision as to what to do first and that’s when you do it left to right.
What is the need for left to right If you are pemdas, Parenthesis first Exponents the multiplication and so.on When you ask you daughter to read, do you instruct her to read from.left to right
A and S have equal priority so the order doesn't matter: S first: - 2 + 6 = 4 A first: 5 - 1 = 4 Going left to right for equal priority operations reduces errors usually so us generally the better method.
He ruins math too with his crappy math skills. PEMDAS comes into play exactly when that stupid division symbol goes away. For this guy's "true passion", he really sucks at it.
It is absolutely appalling that you are not only teaching wrongfully, but misleading 508,000 subscribers. You might have taught middle school and high school math, but I taught math at one the top 10 private schools in the US, and at university, all the way through calculus, and I will prove that what you are teaching is wrong. What is 4 divided by (3-5) x2. Clearly 4 is the numerator, so lets say a=4. Clearly (3-5) is the is the first operation, which is -2, so B =-2, which is multiplied by 2, which constitutes a product, but we will say 2 equals C. So not using caps, this is expressed as a/bc, is equal to a/bx1/c, pretty basic. But what you are doing is saying no, that really a/bc equals a/b x c, while bxc is not a product per this expression. With that, what is the definition of a product clearly as this problem is written, (3-5) equals -2, and that is being multiplied by 2. What you are really saying is not the expression of the problem, 4/(3-5) x2, but rather (4/3-5) x2, which isn't how the problem is written. I can't believe how many people you are misleading. BTW if anybody wants to comment, realize that if you call me wrong, other than you likely have never used differential equations to calculate the effects of changes in tax policy upon GDP, unemployment, and inflation rates, realize that you would be calling wrong the math professors at Duke University, and the PhD authors of every math textbook I taught out of. Again, by taking a, b&c, as noted in the above, that expresses this problem of a/bc, as it isn't written (a/b)c. By the way, I'll put in the link for a great video called Pemdas is a lie, written by a math tutor. Essentially what is taught here is usually pre-algebra, while those who teach algebra and beyond recognize what I have shared, and would state this video is wholly wrong. Particularly for those working with physics and other disciplines, as noted in the video that is attached. My concern is that this is wrongful teaching has screwed up our kids and made them dumber, perhaps which is why we rank 38th in Math or something like that as of a few years ago when compared with the rest of the world.
This comment made me giggle. You didn't even say what you thought the answer was! This is a 5th grade question aimed at adults who've forgotten / want to brush up and you're talking about it like it's a quaternion derivation. Just put the sum into google. It's -4. Obviously. "Taught at one of the top 10 private schools in the US" - what did you teach, woodwork?
Yet another poorly written math problem, Mr RUclips Math Guy! PEMDAS will always bite you in the butt if you keep using that obelus for division. So let's write this PROPERLY: 4 / (3 - 5) x 2 4 / (-2) x 2 4 / -4 -1 Easy peasy! Keep in mind: the division bar IS a grouping symbol! Now let's figure out how to get -4 out of this mess... (4 / (3 - 5)) x 2 (4 / (-2)) x 2 (-2) x 2 -4 There you go Mr RUclips Math Guy! You needed to specify which operation to do first! Please stop leading people astray with these poorly written problem. You are MUCH better than this clickbait!
Except that multiplication and division are operations of an equal level, so they have to be solved from left to right 😉! which means, after you resolve the value in the brackets it is solved from left to right! I learned math without of the acronym abbreviations, just by simple explanations about rules, laws and conventions as well as the syntax of how we write things down to be understood correctly.... it seems this isn't the case any more.

@@padraicbrown6718 So did I.... but ONLY for a horizontal or a fraction line. I was taught that "slash", in an equation written in a straight line, is just another way of writing a division symbol. And since division is a binary operation this equation has three terms, of which one is enclosed in brackets, and once you solve the value in them the equation should be solved from left to right, because division and multiplication are operations of the same level.... in other.... the way I was taught math, your interpretation and result would be correct if the equation would be wrote as 4/2(3-5).... because this -written without the explicit multiplication sign between 2 and the brackets - would mean that everything behind the division bar is grouped together, and the result would be -1
Too much chit-chat. Show the problem, show the correct answer and proceed to work the solution. Other stuff dilutes the content and just turns many of us off.
