@@mathically You are INCORRECT with your "invisible times". __ONLY__ the USA teaches this nonsense in middle/high school. If you ever take math (e.g. physics or engineering) in college/university you'll fail. 16 / 4 ( 3 + 1 ) = 16 / 4 ( 4 ) = 16 / (4 * 4 ) .... aka distributive property... it's math. If a rule applies in one location, it applies everywhere. = 16 / ( 16 ) = 1. Your mistake and it's SAME with ALL U.S. HIGH school teachers ... is inserting a magical multiplication sign. 16 / 4 ( 3 + 1 ) DOES NOT EQUAL 16 / 4 * ( 3 + 1 ) Ask any human (who is suitably trained in math) what does 2x/2x result in? The answer is 1. However with your logic (and the same for Google) the answer is x^2. This is 100% wrong. Similarly try evaluating 3^2x ... that's not 9x ... that's 3^(2x) ... since we don't know what x is ... the expression is already in its simplest form. All of this is explained under JUXTAPOSITION. PLEASE STOP TEACHING PEMDAS. PEMDAS IS ***WRONG*** (unless you're just teaching elementary school math).

​@macbain1395 PEMDAS doesn't break any rules of algebra, the interpretation people lay on expressions DO, however. In addition with the obelus, which is not a vinculum, is basically a fraction with a numerator on the left side and on the right side. Writing in text has a difference between writing in paper, which often uses a vinculum rather than an ambiguous obelus or solidus. The simple PEMDAS interpretation of the expression 16/4(3 + 1) is not breaking any rules of algebra whatsoever, since if we break 16/4 down to its multiplicative inverse, we find that we have that as the coefficient of the term (3 + 1), THEN distribute within the parentheses. That's where you went wrong on the distributive property, the coefficient of (3 + 1) is not 4, but it is 16(4^(-1)) juxtaposition is still in application regardless, you have to remember that without the parentheses to group the entire denominator, say: a/bc, as per the interpretation of a solidus, not a vinculum it goes: a/bc = (a/b)c = ac/b Algebra does not fall apart in the midst of PEMDAS, it's the overcomplication and the misunderstanding of simple mathematical perspective on the given.

Even texas instruments has stated officially, that while implicit multiplication has higher priority than explicit, they are selling primarily to North American school teachers (and their students) and that primary school teachers in North America are the only group explicitly stating that they want to ignore this mathematical rule. College professors, mathemeticians, engineers, physicists, and scientists all teach that implicit multiplication comes first. So do primary school teachers everywhere outside north america. Its a universal thing. Except, for some reason, when it comes to bachelor degree non-mathemeticians teaching children mathematics in north america.

@@kelanth462 16÷4(4) is not the same as 16÷4x4. Using parenthesis makes this implicit multiplication. Using the × symbol makes it explicit multiplication. Left to right at all costs is only taught in North American primary schools. It is UNTAUGHT when you go into mathematics, engineering, physics, medicine, trades. Everywhere that uses mathematics in the real world, outside of teaching children. The rule is implicit, left to right... then explicit left to right. If the model being used is ONLY used in primary schools, but not being used anywhere it applies to real world jobs... and is heavily criticized anywhere it is used outside education... then the education model is incorrect. The answer is 1 because 4(4) takes priority over 16÷4 everywhere it matters in the real world. Especially when the field of advanced mathematics literally says so. And the companies doing otherwise state directly in their manuals that this change only exists because people educating children in one continent have overwhelmingly created demand for an incorrect product. TIs words are literally that this is incorrect, but they are meeting the desires of their largest market.

@Codysurfsup 27 дней назад
No. Literally no. 🤦 It doesn't take a rocket scientist to know that / is the same as ÷ What you've done in your example is added imaginary brackets that didn't exist to begin with. Let me break it down in simple terms. Say you have: 2 / 5 x 5 or 2 ÷ 5 x 5 Both are the same. To put 2 over the entirety of 5 x 5 would require brackets. The problem would need to look like this: 2 / (5 x 5) or 2 ÷ (5 x 5) Those are the same. Now if you wanted to write 2 ÷ 5 x 5 in fraction format it would look like this: 2/5 x 5 But either way you'd still solve from left to right. This is elementary people.

As a poorly recovering math head (have been an on and off math tutor to friends and family since 1963, when algebra was introduced to the class) I despise PEMDAS. Mathematics is universal; PEMDAS is strictly limited to the 17% of the world's population that speaks English. Even more restrictive, only the USA and France use PEMDAS; in the rest of the English speaking world it is BODMAS. In Germany it is "Punktrechnung vor Strichrechnung" and everywhere it is unreliable. We never know if the crafter of the expression recognized PEMDAS. Use parentheses, nested as necessary, to avoid misunderstanding.

You can’t change a parentheses to a multiplication sign. That’s implicit multiplication vs explicit multiplication. Implicit multiplication takes precedence over explicit division and explicit multiplication. It’s been stated by the American Mathematical Society and the American Physical Society says multiplication takes precedence over division in general. PEMDAS was created by an educator guys. Not some mathematical society, and it’s not a mathematical law. Since the beginning of time, implicit multiplication (multiplication by juxtaposition) has always had to be completed before anything else. I hate the fact people try to teach math on RU-vid and don’t even research before they do something.

Perhaps you'd all be better off asking ChatGPT instead of some random RU-vidr:- a) What is 16 ÷ 4(3 + 1) ChatGPT To solve the expression 16 ÷ 4(3 + 1), you need to follow the order of operations, which is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). So, first, you should solve what's inside the parentheses: 3 + 1 = 4 Then, you multiply: 4(4) = 16 Finally, you divide: 16 ÷ 16 = 1 So, 16 ÷ 4(3 + 1) equals 1. ------------------------------------------------------------------------------------- Conversely:- What is 16 ÷ 4 x (3 + 1) ChatGPT To correctly solve the expression 16 ÷ 4 x (3 + 1), we follow the order of operations: Parentheses: Evaluate what's inside the parentheses. Multiplication and Division (from left to right). Addition and Subtraction (from left to right). So: Inside the parentheses, we have 3 + 1 = 4. Now, we perform the multiplication and division from left to right. We first divide 16 by 4: 16 ÷ 4 = 4 Now, we multiply the result by 4: 4 x 4 = 16 So, the result of the expression 16 ÷ 4 x (3 + 1) is 16. ------------------------------------------------------------------------------------- NOTE THE DIFFERENCE IN PRECEDDENCE BETWEEN EXPLICIT AND IMLICIT/JUXTAPOSED MULTIPLICATION.

Ask The AI why it's multiplying before dividing and it will back off and give you the correct solution 16.

@@kelanth462 The AI does it that way because that's the way mathematicians and engineers do it. Some RU-vid content creators (not all, thankfully) think they know better and do it differently - and are just perpetuating errors.

If you rewrite this as fractions it will give you a different answer. PEMDAS does not match the way formulas are solved in engineering and mathematics books. In those books multiplication is done before division. This is a very interesting subject.

@@pillowfromtpotreal They are the modern day British. Self-righteous and ignorant of others. Yes I realize that's a generalization but if it's true for close to 50% ... it's relatively good one. More importantly, they and more relevant to this conversation: 1.) They don't study mathematics to a high enough level 2.) They insist, without even listening, to the other point of view. 3.) Because someone taught them PEMDAS (and then later changed it to Order Of Operations), they think that the world followed. 4.) They spread LIES about it being formalized in 1917 or 14 or whatever -- the truth is that there is NO AGREED CONVENTION ___BUT___ if you bother to ready ISO-80000-2 it clearly says that expressions must be written such that misunderstanding is not possible, i.e. CONVENTION MUST BE AGREED PRIOR. And so on. 5.) Americans are now of the opinion that Google is the answer. Google can be wrong and DEFINITELY IS wrong ... just ask it to calculate "5!!" ... then look up a math book. The answer is 15 but NOT according to Google. 6.) Yes you went to the moon. And yes you were first. Big whoop. Half your population believes it's a hoax and 40% (I think) continues to think the world is flat. Do I really need to go on? If I was arguing with a learned mathematician, sure. But this is tik-tok/youtube gen-pop with no grounding in anything except "I wanna be rich and I don't want to go anything".

And that's exactly NOT what mathematicians, physicists and engineers do... and also all math books or papers. Also it's not what HP calculators do. PEMDAS is not the only rule. PEMDAS is used to teach kids. For mathematicians, the answer is 1. And also for my HP 10s.

From what I remember TI and cheaper calcs from certain companies (that use TI chips) use pure PEMDAS but even they have a big old warning in their manuals to add extra brackets around implied multiplication to get the correct answer

She's clearly US educated, i.e. deficient in math. Note the way that she writes X. Lack of cursive lettering. This is literally why people need to be (i) home-schooled. (ii) foreign schooled (e.g. Europe) (iii) have to retake math for science/engineering courses.
