Both (6÷2)*(1+2) and 6÷(2*(1+2)) are plausible way to interpret what was written, which stands out to you as the most correct is going to depend where, when and how much you studied math. If I came across it sight unseen without other context clues I'd definitely assume the second though.

No mathematician or scientist ever uses ÷
I've never seen that notation throughout my entire math degree

The actual mathematician jargon for inverse is to attach ^(-1) to everything no matter what the operation even if it's like group addition or something, and the general scientist jargon is to either write a big fraction in LaTeX (or on a blackboard or on paper) or use the "/, //" operators in comp sci (with brackets to group the expressions)

"÷" is some stupid shit they teach you in 3rd grade and never again, they should really consider switching all uses of that to "/" and then just introduce brackets if you want to start teaching PEMDAS

No, you're wrong. 6/2(1+2) only requires the 1+2 to be performed first.

The ambiguity is in the notation, not the math itself. When I read it like a computer input (with no context on 2 distributing into (1+2)), I also get 9. To get 1, you have to do something like 6/2/(1+2).

Writing / or ÷ matters fuck all. What people get wrong is the order of operations when they see 2(3). They think it is a priority operation, but it isn't because the 2 is not in the parentheses.
6/2(3) is the same as 6/2*3, which gets solved from left to right and is 9.

So the main issue is how people are interpreting the multiplication/division part. So for example, what is xyz/xyz? Is it 1, or is it (yz)^2? A computer would spit out the latter, while a human may read it as dividing all by xyz. Again, shitty notation will do that.

Why do popular "math problems" on social media always revolve around semantics? It's never about math itself. It's never a problem where you have to find all n so that a polynomial P(n) becomes a prime number where you can use some neat math tricks. The same goes for physics. It's always about the philosophy behind it, the less testable the better and the more you'll find discussions about it. You won't find people talking about how the Ward identity applies to tree level QCD diagrams, but you'll hear a lot about particle or wave, or many worlds. Vtubers for this feel?

There are only 2 factors in your example, so it's unambiguous there. The OP has 3 factors and the algebraic expression in my example has 6. I used it to illustrate how confusing it can be with bad or misleading notation, but perhaps that's the whole point of the exercise.

9 is wrong because writing a fraction in a single line is fundamentally wrong to begin with, and don't even reply to me using /, that shit isn't a fraction either, a fraction is one number over the other, not one number besides another

So there is a correct answer, but the notation is as retarded and confusing as can be, so I wouldn't trust the average person to use it corretly, because they're retarded. But the average person would get this correct 9/10 times if fractions were used. So it's not a math problem, it's a notation problem.

This is why you need to be explicit when writing stuff down. Most people are taught to do multiplication and division from left to right.

Well, the question is unclear. If I were asked this question on the test, I'd ask for clarification if the question means:

(6 / (2 * (1 + 2)))
OR
((6 / 2) * (1 + 2))

Due to there being no operator in front of the brackets, there is ambiguity in the question.

All basic operations are binary, thus need TWO operands in order ( Binary operation. Encyclopedia of Mathematics. URL: http://encyclopediaofmath.org/index.php?title=Binary_operation&oldid=39754))

If this was a question in Uni level, the correct answer would be to point out this.

for the last time, the left to right bullshit doesn't exist, if you write the equation correctly it doesn't matter as long as you respect the order of operations

Except "multiplication before division" or "addition before subtraction" is complete bullshit. They have the same precedence.
>>53771228 is right, it's a stupid question because it's all in the notation. If you simply imagine a * between the 2 and the (1+2), then the answer is 9. But intuitively, you might read it the way fishman wrote, because the missing * puts the 2 and (1+2) closer to each other than to the 6. So the real question is, is the missing * a purely lexical/visual thing or does it imply grouping too?
Unlike programming languages, there isn't really a universally correct way to write math. Everyone does it slightly differently. Mathmaticians can't even fucking decide whether ℕ includes 0, or whether variables that represent vectors should have a little horizontal line above the letter (or maybe below? Or maybe a tilde? Or a little arrow?). "6/2(1+2)" is ambiguous.

She brought up the other countries orders of operation but tried to call out PEMDAS. And she explained it incorrectly. Either my C level elementary school had a top tier Math professor as a teacher or most of the people here including her slept through basic mathematics as a kid.

MD are only equal in basic equations they are not equal when implied multiplication is involved. The old textbooks from the 90’s literally teach you about that.

Your post and the answers you're getting perfectly illustrate my point. There's no consensus.
Personally, I actually read it as "6/(2*(1+2))" at first glance. But I studied CS (which includes plenty of math) and never heard of "implicit multiplication". I just looked it up and the English wikipedia article on "Order of operations" has a sentence on it which begins with "In some of the academic literature [...]". Yeah, "some". So who the fuck knows

Not if the Multiplication is connected to Parentheses. Parentheses Trump everything. The 2() takes priority over 6÷2. When a Multiple is attached to a Parentheses it is treated as part of the Parentheses but take second priority to the formula inside the Parentheses.

Calculators don’t have a brain. If you can’t solve it without it you can’t do it with one.

6 is being divided by the entire equation not just the 2 because 2 is sticking to the parentheses.

You’re supposed to imagine a parentheses there so you don’t make a mistake. It’s also how you’re supposed to write it in a calculator. Years of calculus to teach basic arithmetic on an image board

[Anonymous No.]

Ah I'm seeing what has happened here now. 9 is correct because of modern usage. The problem should actually be written:

6÷(2(1+2))

Because at some point they changed how they do orders which in the past was more strict about divisions and multiplication.

To avoid confusion because modern mathematicians are retarded and can't understand nuance and like to waste ink on paper making things look complicated.

ALWAYS do what's in the brackets FIRST. ALWAYS.
Then it's just a choice for whether multi or division takes priority and personally I prefer multi
so 3 x 2 = 6 and then divide 6 by 6 which is one.
If you go division before multi you do 6/2 = 3 then x by 3 = 9

It's a choice between orders so BIDMAS/BODMAS VS PEMDAS
None of these answers are actually wrong

that's not how math works retard, math is objective

[Anonymous No.]

>>53781099
And objectively I answered the question in both ways. What's the problem?
We don't have a way of objectively choosing the optimum order since there isn't a way to decide whether something has more value, say whether addition is worth more than subtraction, that makes no sense.
So choose.
The PEMDAS rule is an acronym that stands for parentheses, exponents, multiplication, division, addition, and subtraction.
vs
BIDMAS stands for brackets, indices, division, multiplication, addition, and subtraction.

[Anonymous No.]

well, that's confusing.

If everything is in the same line, 9, because PEMDAS.
If it's like fishman wrote, then 1 because everything under the fraction is separated.

>>53781209
Retard both rules should have the same answers to any one math problem. If you did the calculations correctly (do it objectively) you would get the right answer. BIDMAS and PEMDAS might be slightly different, but the answers should be the same. The order of operations are there just to make sure that everyone is talking about the same thing.

[Anonymous No.]

In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression.

For example, in mathematics and most computer languages, multiplication is granted a higher precedence than addition, and it has been this way since the introduction of modern algebraic notation.[1][2] Thus, the expression 1 + 2 × 3 is interpreted to have the value 1 + (2 × 3) = 7, and not (1 + 2) × 3 = 9. When exponents were introduced in the 16th and 17th centuries, they were given precedence over both addition and multiplication, and could be placed only as a superscript to the right of their base.[1] Thus 3 + 52 = 28 and 3 × 52 = 75.

These conventions exist to avoid notational ambiguity while allowing notation to be as brief as possible. Where it is desired to override the precedence conventions, or even simply to emphasize them, parentheses ( ) can be used. For example, (2 + 3) × 4 = 20 forces addition to precede multiplication, while (3 + 5)2 = 64 forces addition to precede exponentiation. If multiple pairs of parentheses are required in a mathematical expression (such as in the case of nested parentheses), the parentheses may be replaced by brackets or braces to avoid confusion, as in [2 × (3 + 4)] − 5 = 9.

>Internet memes sometimes present ambiguous expressions that cause disputes and increase web traffic.[3][4] Most of these ambiguous expressions involve mixed division and multiplication, where there is no general agreement about the order of operations.

multiplication by juxtaposition has higher precedence that multiplication / division with an explicit infix operator
2(1+2) is evaluated before 6 / 2.

>>53771228
except that there's more or less concensus on a well defined order of operations in the academic maths community. The problem is that its never taught in high school.
Obviously thats just consensus and man made agreements, but so is literally all of maths.
