oh brother, it's this nonsense again. the calculator is right, modern software that works blindly left to right is wrong. this becomes obvious in algebra with variablesthe distributive property is being murdered by retards who slept through middle school algebra and this will probably result in a plane crashing into a stadium full of orphans at some point

@deprecated_ii i just did it in my head real quick and also got 1, I don't understand where the confusion is coming from?im not fantastic at math (anymore) and don't remember the reasoning for a lot of things, but like...isn't this just order of operations?

it's 1, putting a number next to a bracket makes it an implicit multiplication that binds stronger than other operations, this is obvious when you make a substitutiony = 6/2(1+2)x = (1+2)y = 6/2xy = 3/xy = 3/(1+2)y = 3/3y = 1A stronger argument is that the defining property of multiplication is that it distributes over addition, a(x+y) = ax + ayAnybody saying the answer is 9 is either never took a mathematics class after high school or is deliberately giving the wrong answer like a redditor

@udongle @bronze @deprecated_ii the P of pemdas is "you simplify shit in the parentheses first". It's a rule against 2*(2+3) getting solved like 2*2+3. You do not need to distribute anything in the original example because you can simplify (2+1) to 3.

@udongle @deprecated_ii @monsterislandcolonizer Incidentally this is why math classes starting from algebra strongly prefer just writing division as a fraction, because it makes it far more obvious what the denominator actually is. Using a calculator, I would use extra parentheses to make sure it's being parsed how I want, because I can't be bothered to keep track of how the calculator is programmed.

@deprecated_ii @monsterislandcolonizer Every one of these debates could be avoided if we just use a big line for division instead of the ÷ symbol. That symbol in an equation feels completely unnatural when you want to piece together an equation. The line with the numerator and denominator defined (be it a single number or an equation) is easier to work with.

This is how coefficients are handled in algebra, you should be able to replace any part of any arithmetic expression with a variable and perform transformations, and then get the same answer when you substitute back in the original part of the expression.No mathematician would ever interpret 30/5x as meaning (30/5)xEvery taylor series is written Σaₙ/n!, nobody would ever interpret that as [Σaₙ/n]!

@deprecated_ii btw since ARM doesn't have integer division instructions, a common optimization is to replace division by a constant with multiplication by a magic number. with int n, n/2 is compiled to n*magic, and it works and is much faster.

Placing a number directly adjacent to a parenthesis means you treat it like a coefficient, the same way that 7y means 7 * y, it's treated as a single term.

Exactly, any operation that isn't associative should have tons of parenthesis to guarantee the calculator computes exactly what you mean.there is a lot of interesting nerds details about how to parse symbolic expressions and evaluate them, how doing that gets you 90% of the way to a working compiler, big rabbit hole and this microsoft shill is shitting over it all

@deprecated_ii @warmbeverageenjoyer No, we get 9 because ÷ and / are treated as the same symbol, meaning, that (1+2) goes first, and then, we end up with 6/2*3 = 3*3 = 9And it's boring to explain this system over and over and over again.But division is the same as multiplication.If I re-write it as 6* (1/2) * (1+2), then there is no argument to be had.

@deprecated_ii @LukeAlmighty @warmbeverageenjoyer No, you are wrong here. The problem here is that it's ambiguous. The only thing unambiguous here is that the parenthesis come first.6 / 2 * 3This can be either (6 / 2) * 3 or 6 / (2 * 3) and will either by 9 or 1. Typically, division will be written as a fraction or parenthesis get added. But the answer isn't wrong. More parenthesis need to be added.The distributive property doesn't apply here at all.

@deprecated_ii @warmbeverageenjoyer @LukeAlmighty but here's the thing: why does the distributive property happen before the division?I understand, when you talk in terms of algebra, it makes sense that 6/2a, where a = 1+2 will give you the result 1, but the equation 6/2(1+2) is not algebra, and 2(1+2) is just a different way to write 2 * (1+2), the fact the 2 is next to the parenthesis doesn't turn it into a special operator that bypasses PEMDAS.In the end, math is just a language used to express calculations, and just like any language, there are some conventions, and it requires some clarity on the part of the person writing it. Just like the other stupid equation that caused internet drama earlier this year, this is something that can be solved with the liberal use of parenthesis, you can't just have a regular equation with no context whatsoever and expect people to treat it as an algebraic equation.

@LukeAlmighty @warmbeverageenjoyer You're using a separate set of rules than is used anywhere else in math. I just recently refreshed myself on college level math, calculus and discrete math and some linear algebra, and if I was doing what you claim is the correct order of operations for all that I would have rarely gotten a correct answer.The 2 doesn't "get there", it's already there. 6 = (2+4) = 2(1+2), that's how it works, you don't get to throw away part of the 6 just because it left the inside of the parentheses.

@deprecated_ii @warmbeverageenjoyer @LukeAlmighty OK, here I have a mathematician explaining this exact equation in a way that's easier than what I would do. And I'll use it because he reached the same conclusion as me, so I have confirmation bias.https://invidious.varishangout.net/watch?v=URcUvFIUIhQBut note that he doesn't say anything about the distributive property, because it really doesn't fit here. Saying that 2(1+2) is it's own equation that must be solved separately is not true, because there is nothing saying it is. You are assuming that 2(1+2) is just a 6 that was split, instead of being a equation that was reached through the insertion of numbers into variables or through the solving of previous equations.Note that I had a wrong assumption in my last post, because I was taking a look at my college algebra books, and even in algebra you have a liberal use of parenthesis to avoid this kind of confusion.6/2a is completely different from 6/(2a), wherein the first one is seen as6__ a2and the second is seen as6__2a(the formatting is terrible, but I think it can be understood).

@Suzu @warmbeverageenjoyer @LukeAlmighty You don't get to decide the distributive property just doesn't apply here. That's not how math works. If you replace (1+2) with (a+b) you can't resolve the inside into a single element anymore, and you don't get to throw the coefficient away.The core problem is apparently half the population thinks parentheses mean multiplication only, and that's just not the reality.The only thing I'll concede about this at all is it's clear that a lot of people find the way the equation is written confusing. That doesn't mean their confused interpretation is correct.

@EdBoatConnoisseur @basadeskaiser @deprecated_ii >PEJMDASdoesnt the 'M' in PEMDAS already imply that multiplication (implied or not) goes before division though? I would assume most math students would be at least intelligent enough to understand that if x = (1+2), that the connotation of 6/2x is the same as 6/2(1+2). and that you can be explicit with a calculator anyway by specifying the order of operations just by using (). If their answers are consistently wrong I would assume they would try being more explicit in how they define operations :ehh:

@Suzu @warmbeverageenjoyer @LukeAlmighty If you wanted to distribute the 6/2, you would reduce it to 3, or put 6/2 itself in parentheses. You didn't. So you don't want to distribute it. That's the interpretation that's going to be right 99.9% of the time unless the author has malicious intent.My understanding of order of operations carried me cleanly through several years of university math. Yeah, I'm pretty confident in my understanding.And I suspect nobody who is confused by this actually has problems with order of operations in university math classes either. But something about a simple equation with no variables breaks their brains, perhaps *because* 6/2 is so tempting to reduce immediately.

@RealAkoSuminoe @LukeAlmighty @warmbeverageenjoyer Only if you ignore the 2 being adjacent to the parentheses by interpreting it as nothing but a multiplication sign. Which is a stupid interpretation and not something you would do in most other contexts.Obviously I have to agree that the statement is confusing because so many of you are confused about it. I do not have to agree that it's reasonable, all things considered, to arrive at 9 as the answer.

@LukeAlmighty @deprecated_ii By adding another pair of parenthesis, we get a very different pretty print, the one you would expect to equal 1.Also, I don't think I've ever read a specification that has a implicit factor operator. Factoring doesn't even need its own operator, since it can be easily represented by multiplication.I would be shocked to find anyone, working on an important project, not using pairs of parenthesis for precise explicit grouping.Bottom line, 6/2*(1+2) =/= 6/(2*(1+2)), on literally any system I've used for more than a decade, and it would be silly to try and change that now.

@Suzu @deprecated_ii @LukeAlmighty @warmbeverageenjoyer I think what confuses people is 2(3) being written as it is. You have 6/2 having a symbol while 2(3) doesn't, even though this is just a short way of writing it and 6/2(3) = 6/2*(3). this then leads to thinking the one without a symbol is "closer" and needs to be solved first. Though your take is likely true as well.

@deprecated_ii @warmbeverageenjoyer @LukeAlmighty @Feinmuehrer That's not a cope.The people who were doing that were using an archaic denotation that is controversial because even in the historic sense it's not sure it was like that, and in this denotation somehow the ÷ symbol was different from the / symbol. The mathematician in the video I posted talk about this.Your mistake here is in using the distributive property in a completely arbitrary way and deciding that this is the correct way, when we have mathematicians, researchers and tools saying the complete opposite: that you solve left to right and then distribute.As I mentioned, even in algebra they use parenthesis to avoid this, 6/2a is different from 6/(2a), which is what you are doing here.

@deprecated_ii Oh I love this conversation, we had it before! Yes it's 1, but... just wanted to make a little correction: even software that evaluates blindly left to right is correct, simply by virtue of the way lexers work. Here, "EXP" means "Expression," so the calculator's software still works correctly. The calculator then terminates the sequence because there is nothing after the last closed-parenthesis. Then you evaluate this bottom up, dividing 6 by 6 to get 1. :towa_thumb: But yes, to really settle this tired old nonsense, you simply need to turn everything into variables and find that the distributive property is what decisively makes this expression evaluate into 1.

@Suzu @MCMLXVIIOTG @warmbeverageenjoyer @LukeAlmighty @Feinmuehrer Stop using PEMDAS as a mental crutch and maybe you won't get confused. This whole discussion just shows PEMDAS is worthless because it isn't taught correctly and is interpreted multiple ways.

@Suzu @warmbeverageenjoyer @LukeAlmighty @MCMLXVIIOTG @Feinmuehrer 9, because 2 * (1+2) is not the exact same expression as 2(1+2). which is what I've been trying to get across this entire timeand PEMDAS is a mental crutch. I haven't actually thought "please excuse my dear aunt sally" since middle school, I just *know* how to execute algebra, and I do so accurately

@deprecated_ii @Suzu @MCMLXVIIOTG @warmbeverageenjoyer @LukeAlmighty @Feinmuehrer Literally just read the wikipedia article. It talks about this exact issue.There is a physics journal that agrees with your conclusion because they adjust the order of operations to put multiplication by juxtaposition at a higher precedence than normal multiplication and division, but they still tell people to use parenthesis to make sure that it's not used anywhere. It's an acknowledged ambiguity in the way we write mathematics.You are still wrong because this has nothing whatsoever to do with the distributive property.6/2(1+2) = (1*6/2 + 2*6/2) = 3 + 6 = 9en.wikipedia.org/wiki/Order_of_operations

@deprecated_ii @StoleMyThundersBalls @monsterislandcolonizer Turning 2(1+2) into 2*(1+2) isn't an error. That's what it literally means. Distributing the 2 over (1+2) is the same as 2*3. The error is dividing 6 by 2 when this stupid fucking linear math notation that nobody ever uses in real life wanted 6 to be divided by all of 2(1+2). That this bullshit encourages you to read 2(1+2) separately from 2*(1+2) is just another reason to drop it. Use some defined programming language or use a real math notation or use copious parentheses.

@deprecated_ii @Suzu @warmbeverageenjoyer @LukeAlmighty @MCMLXVIIOTG @Feinmuehrer again, suzu doesn't need to learn about implied multiplication. suzu already knows that 2() means 2*(), and JUST SAID SO. The dispute here is not about multiplication but division. Order of operations is complete distraction from the simple meaning of the notation here: WHAT is being divided by WHAT. And saying, oh it's special because you have a fetish for a sixth-grade abbreviation of multiplication symbols, so that later it'll be easier to talk about polynomials, won't save you when you get to slightly more complex expressions.

@deprecated_ii Its 9. 6/2*3. Nothing indicates that you are expected to multiply before division, or that 2*(1+2) is supposed to be 6/(2*(1+2)). From left to right, operations INSIDE parenthesis take precedence, multiplications and divisions (and root, power, etc) take priority over addition and subtraction.

@deprecated_ii @apropos @warmbeverageenjoyer @LukeAlmighty @MCMLXVIIOTG @Feinmuehrer that's because it is.The only way you reach 1 is if you magically turn the implicit operator into a special operator that is super awesome and takes precedence over everything else, which is completely wrong according to the ISO standard I sent you before, and even the people who use it that way say it's wrong and that ideally you should put parenthesis, as was mentioned in the thread before.

Other people with other calculators may have had to read their manuals more correctly, but punching shit into a calculator isn't math to begin with20 years ago I had an HP49G that would build a two-dimensional expression with precise division bars, the same as you'd draw on paper. If they're making other calculators you should leave them to accounts.

Evaluate paren first, so this is correct>y = 6/2xBut for clarity it should be written as:y = 6 / 2 * xy = 6 / 2 * 3The interpretation of this comes down to whether you eval mult and div left to right, or consider mult higher priority.see https://en.wikipedia.org/wiki/Order_of_operations#Mixed_division_and_multiplication>In some of the academic literature, multiplication denoted by juxtaposition (also known as implied multiplication) is interpreted as having higher precedence than division, so that 1 ÷ 2n equals 1 ÷ (2n), not (1 ÷ 2)n.[1] For example, the manuscript submission instructions for the Physical Review journals state that multiplication is of higher precedence than division,[24] and this is also the convention observed in prominent physics textbooks such as the Course of Theoretical Physics by Landau and Lifshitz and the Feynman Lectures on Physics.[d]>This ambiguity is often exploited in internet memes such as "8÷2(2+2)", for which there are two conflicting interpretations: 8÷[2(2+2)] = 1 and [8÷2](2+2) = 16.[25]

@LoliHat @Feinmuehrer @LukeAlmighty @MCMLXVIIOTG @apropos @deprecated_ii @warmbeverageenjoyer and when you don't?You have an order of precedence of operations, and when they have the same precedence, you solve from left to right, it's pretty simple, actually.

@apropos I recall in precalc they at least used to have a way to vocalize the parenthetical version vs the unparenthetical:"six plus three divided by two" --> 6+3/2"six plus three in quantity divided by two" --> (6+3)/2The thing is, these little gotcha math questions are not taken seriously by any mathematicians or university courses.

And RPN has it's uses, but it can become too verbose and unwieldy for most stuff.

Meanwhile you think just swearing and saying you're not reading anymore, and accusing people of engaging in strawmen and being completely wrong about that, are all fine?You're so mad you didn't even notice what a bad reply I made just now. Order of operation are all about math notation, as a rule like "M before A" is how you can write 2*3+4 without needing parentheses. The real difference is again that PEMDAS applies to common math notation and your linear / handling that cares about 2() abbreviations is only between you and your calculator.

@ItsSkyDragonz It depends how you treat the parentheses. There are two extremely opinionated schools of thought.I would interpret it as 1. But evidently, 9 is also acceptable, and we're supposed to complain about math notation being confusing.

@LukeAlmighty @warmbeverageenjoyer @deprecated_ii There is no multiplication operation in this problem. Parenthesis represent anonymous inline variables, not a multiplier.Saying "2(1+2)" is the same as saying "2x where x=1+2".Parenthesis are just a shorter, more convenient way of doing that.

@rightwingsjw @deprecated_ii @apropos @monsterislandcolonizer My take: Concatenation is an abbreviation for multiplication, and an abbreviation should never obey different rules than what it stands for. So the expression 6/2(1+2) should mean the same thing as 6/2*(1+2). The point of parentheses is that it's always valid to simplify what's in the parentheses first. So it should mean 6/2*3 = 9. Someone said that the distributive property means you must do 2*(1+2) = 2*1+2*2 right off the bat. This is wrong for two reasons: first, the distributive property is just a true statement, not a command. You're never forced to apply it. Second, there are situations where you obviously shouldn't apply it first, such as 6^2*(1+2). So I don't find the "distributive property" argument compelling. There are some situations where operators of equal precedence are grouped from the right, by convention. For example, if someone writes 3^3^3, they usually mean 3^(3^3) and not (3^3)^3. But I don't buy this for multiplication and division. @deprecated_ii makes a good point though: if you see 6/2x, there's a fair chance that they mean 6/(2x). It's ambiguous though: what if you opened someone's notes and saw the expression 5/2 + 6/2x + 7/2x^2 + 8/2x^3? I'd bet they're talking about a polynomial in x, where the coefficients are 5/1, 6/2, 7/2, 8/2. No matter how you look at it, the expression is ambiguous. The real answer is that when you see 6/2(1+2) you should feel disgusted that someone was so lazy that they couldn't bother to make their meaning clear. Aryans do not write expressions like 6/2(1+2). If a plane crashes into a stadium full of orphans, it's gonna be because someone was too lazy to fully document their work, or someone was discouraged from asking for clarification, and *not* because the airplane manufacturer should have chosen one over-complicated system for parsing ambiguous expressions instead of another.

Parenthesis, exponents, multiplication, division, addition, subtraction. Do the parenthesis first either multiplying out the 2 to 1 and 2 = 2(1+2)=(2+4)=6 or do what's inside parenthesis (1+2)=3 then time by 2 = 6. Then divide by 6.

@Cayhr @deprecated_ii here is the thing, I'll try to make it easier by turning everything into a multiplication:We can agree that 6 / 2 can be written as 6 * (1/2) (the 1/2 is a fraction, 1 over 2, but I can't format it that way in fedi), right?So we can say that 6/2(1+2) can be written as 6 * (1/2)(1 + 2), right?Associative properties with multiplication says that I can evaluate it either as (6 * (1/2)) * (1 + 2) or I can evaluate it as 6 * ((1/2) * (1+2)). Heck, I can even go completely wild and evaluate it as (6 * (1 + 2)) * (1/2). This is "high math". This is using the associative properties. Fuck, I can even use distributive right now. I can use distributive either by distributing 6 (1 + 2) or by distributing (1/2)(1 + 2). What will be the result?The problem here is that by just blindingly using the distributive property in 2(1+2), you guys are turning (1+2) into 1/(1+2) (you are throwing the (1+2) part down, to the denominator). And that's wrong, unless you have a parenthesis separating the whole denominator, like 6/(2(1+2)). You can't just arbitrarily decide where you are applying the properties in just a part of the equation, you can't decide that 2(1+2) is a single number based on gut feeling. It doesn't matter if you did it before and it worked, it's wrong. It's a wrong notation, and in this specific equation, it makes you reach the wrong conclusion.

@Cayhr This is wrong.(1) Lexers just turn a string of text into a list of tokens, and don't have any mechanism for operator precedence at all. The result of any lexer will just be: NUM(6) DIV NUM(2) LPAREN NUM(1) PLUS NUM(2) RPAREN(2) To actually create an AST, that requires us to parse this list, which gives us the ability to declare operator precedence. Without it, you can easily have it parse: 2 * 3 + 4And it will happily parse it as: 2 * (3 + 4)Because it just comes down to the order in which the AST was assembled. In fact, it will actually evaluate right to left consistently, and this is masked by the fact that the original expression had parenthesis at the right-most side.(3) Also, your analysis gives the impression that if you were to pass it something with an explicit multiplication sign that it will still work this way, which is something that deprecated wasn't even claiming: 6 / 2 * (2 + 1) = 1The entire debate is about whether the "/" or "*" gets evaluated first, and if you actually have an explicit multiplication sign, then it would be uncontroversial that it would be parsed like so: (6 / 2) * (2 + 1) = 3 * 3 = 9As I mentioned in a prior post, it's because the multiplication is by juxtaposition that some people give it a higher level of precedence: 6 / 2(2 + 1) = 6 / (2 * (2 + 1)) = 1(4) The distributive property doesn't matter here because you can do the same thing with the other order of operations: (6 / 2) * (2 + 1) = 2 * (6 / 2) + 1 * (6 / 2) = 6 + 3 = 9Making a fancy graphic for this doesn't change what the actual debate is about.

@RealAkoSuminoe Yeah this is very fair, I'm reading more and I haven't been able to recall nor find any literature on implicit multiplication laws. Is the 2 bound to the parenthesis? Where did that concept come from, and why do I think that? Because 6/2(3)... well, that would yield 9. So in a way I myself have rewritten the problem to be interpreted in the way I wanted it to be.I started at either 9 or 1, to it's definitely 1, but now I'm starting to get confused again. Haha, such is the folly of hubris. The truth is that this expression simply SUCKS.This is also why we just get redundant with parentheses to ensure maximum clarity. When I was in Calc 3 I used parentheses exhaustively for even simple expressions, and a few classmates would cause problems for themselves during evaluation steps and the error would propagate. The big problem with 6/2(1+2) is that none of the numbers have any meaning, so what even is the point of evaluating it?Still, it was fun to make the infographic supporting the answer is 1. Thanks a lot for your input.This is the article I was looking at btw https://www.themathdoctors.org/order-of-operations-implicit-multiplication/

@Cayhr Fully agree with this. It's a bad expression and if asked to evaluate the first step should always be to ask for a clarification.According to Wikipedia, the rule about multiplication by juxtaposition having a higher precedence came from a physics journal, but that journal still says to avoid writing expressions that would use that.

@RealAkoSuminoe I'm thinking back to when I was programming a pseudo physics engine in Unity when I was making a platforming game prototype. Each number in an operation had a meaning, and I knew how the operations would need to be done.If the contentious expression was in the context of an actual problem, it could have been formulated according to the problem requirement of: "X divided by twice the sum of Y and Z." Now the numbers have meaning, and this expression is much more clear. But in another context it could be "half A times the sum of B and C," and we would just put parentheses to distinguish it as such. 6/(2(1+2)) vs (6/2)(1+2).In a short amount of time you have rectified my arrogant outlook on the problem back to where I originally was on ambiguity, so I thank you for that :nana_thumb:

@monsterislandcolonizer @deprecated_ii 2(1+2) happens before 6÷ I guess.

@NEETzsche @apropos @houseoftolstoy @deprecated_ii @monsterislandcolonizer fun fact: while the rest of the world uses "X by Y" to mean multiplication (think "2 by 4 brick"), it's common in india for "X by Y" to mean "X divided by Y"

@theorytoe @basadeskaiser @EdBoatConnoisseur @deprecated_ii >wait really???nah we all use rpn now>multiplication (implied or not) goes before divisionit's supposed to be parsed as P, E, M/D, A/S

@theorytoe @EdBoatConnoisseur @basadeskaiser @deprecated_ii oh i see your confusion, 6/2x has implied multiplication (your wording) so 2x is bound together

@apropos @warmbeverageenjoyer @LukeAlmighty @MCMLXVIIOTG @deprecated_ii @Feinmuehrer @Suzu algebraic notation is quite simply a language involving numbers rather than words which leaves it open to interpretation, and the common interpretation is that (x+1)(y-1) is one term, same with 2x or 2(1+2), and the only "ambiguity" comes from writing out all your formula on one line when in literature youre going to see divisor over dividend and terms are more visually-grouped that way. doesnt change the boundaries of the terms youre working with though, doesnt change that implied multiplication is *most commonly* understood to have higher precedence than explicit mul/div, and doesnt change the fact that its easier to type fewer parens and if you really want to get 9 from OP's formula, literally just fucking write it as (6÷2)(1+2) and stop bitching

@opal @theorytoe @basadeskaiser @deprecated_ii yeh any sane calculator would treat 6/2(1+2) as 6/(2*(1+2)) but that isn’t how calculators have been programmed for some time nor how (american) teachers have been teaching math…

@deprecated_ii @theorytoe @basadeskaiser @EdBoatConnoisseur texas instruments is too stupid to parse :For(X,0,9:If 0 without slowing to a halt either so i wasnt too surprised

@deprecated_ii @opal @theorytoe @basadeskaiser again, the video i posted explains the issue, ti calculators have been the “standar” classroom calculator of the USA for some time now, as a result texas instruments has had to comply with the request of USA teachers, while casio for a time did comply with those demands but reverted to the correct behaviour after complains and petitions from teachers, professors and mathematicians from europe and asia.

@deprecated_ii You can consistently define the order of operations to work either way. In serious work, people generally don't write non associative operations in a way where you need a special rule to figure out what the correct order of application is, because that's dumb. I have never seen the divides symbol used outside elementary algebra and arithmetic classes.
