Saw pic related posted here yesterday. I was absolutely amazed

The answer is 1 right? Right???

is it....3?

The answer is 9. Right?

>>36341428
9-3 is 6
6/(1/3) is 18
18+1 is 19

the answer is 19

>>36341428
I change my answer from 3 to 19, I did the division wrong.
So OP what is it?

>>36341428
answer is 1
according to PEMDAS, you calculate division first
three divded by one third is nine.
nine subtracted from nine is zero
zero plus one is one

The answer my old chap is 9

>>36341486
>>36341679
This. 3/(1/3)=1 and it's the first step you do.

needs brackets, whoever wrote this is a dumb cunt

>>36341428
There is an implicit parenthesis around the vertical 1/3, so it is calculated first. Then the other division, then the addition/subtraction. Answer is 1.

division and multiplication come first. so first you divide 3 by 1/3. dividing by fractions is basically multiplying by the enumerator. then you carry out the operations in the regular order. having done so, the answer you get is 1.

>>36341723
It's not multiplication it's division you dunce.

I learn it this way. When dividing a fraction from anything you multiply by it's reciprocal instead.
3/(1/3) turns into 3 * 3/1 then simplify 3 * 3 = 9.

>>36341750
You're an idiot. It doesn't need brackets.

>>36341428
is the answer 1?
that's what I got after doing the math

>1/3 = 0.333333
>3/0.33333 = 9.0000009
>9 - 9 + 1
>9 - 10
>=1

>>36341723
Heres the part where we throw our heads back and laugh

>>36341850
You are correct. The math is wrong, but it's 1.

>>36341850
You made two mistakes that canceled eachother out and got it right gg

>>36341894
>>36341909
I took special education math at school, but I can do it...

BIDMAS rules
Divide first, 3 divided by a third is the same as 3*3 so 9.
Add 1 is 10
Subtract 9 is 1
Wow robots. Is American education really that bad?

>>36341428
Depends on how you approach it. Different math educations will yield different steps to solve vague problems without parenthesis like you have posted. Some people follow PEMDAS, others go from left to right. Maybe if you were less obvious with that paragraph it would have been good bait.

>>36341564
>>36341750
>>36341757

PEMDAS is fake shit you fucking morons. Stop acting like it's holy gospel. The correct way to do it is from left to right.

>>36341944
>american education meme

In the last thread it was a brit who kept arguing that it's -1, and that there were "multiple answers" because brackets weren't provided.

Besides, America has 4 times the population of the most populated European country. A nation with a lot of people living in it is bound to have at least a few idiots

>>36341972

I'm asian so I go from right to left. And we are known to be superior in math.

>>36342041
now that i think about it, mathematics is some really abstract bullshit. like, who decided what operation comes after what. there is no tangible way to see how it happens irl, is there? i'm just gonna go by what they taught me in school cause fuck math.

>>36341428
9 - (3 / (1/3)) + 1
=9 - (3 * 3) + 1
=9 - 9 + 1
=1

Punch 3 / (1/3) into a calculator if you don't believe it's equivalent to 3 * 3

Anon you have to prioritise you divisions over the addition so it's

9 + (-3) / (1/3) + 1 =
9 + (-3) x 3 + 1 =
9 + (-9) +1 =
9 - 9 + 1 =
0 + 1 =

It s easy Anon, just go step by step and you ll make it one day :)

>>36342098
I fully agree with this. Math seems like a subjective subject. I don't see how you can find an objective answer out of a really large problem. Obviously 1 plus 1 equals 2 but when you get into shit like calculus that seems too abstract to apply in real life.

>>36342125
It's 3.

It's wrong isn't it?

>>36341972
>left to right
literally only computers do this. Even computer programmers are taught BEDMAS and use brackets when writing out math functions in the computers, unless they're going for some super-optimized equation

>>36341454
Yes it is.

Anyone arrogant shit who got a different answer but cant stand being wrong should plug it into Wolfram before embarrassing themself in this thread.

>>36341909
>>36341894
wait, what did I get wrong actually? I want to avoid this error in the future.

>>36342163
I'm literally brain damaged and I knew the answer was 1. I did the math wrong and knew it was 1. Put me in a coma for 9 years and when I wake up, the answer I will have gotten is 1.

Well PEDMAS or BIDMAS or BODMAS is all just an agreed thing. Since division and multiplication can cancel each other out and addition and subtraction can cancel each other out it doesn't matter which order you do these in as long as it is a DM or AS pair.
The only reason it exists is just so it is agreed universally. This is so people know when to put brackets in and so it saves us having to use brackets for everything.

>>36341972
Not bait, you are just stupid. There is one right answer and anyone with a three-figure IQ and an elementary education will get it right.

>>36341428
i did it like this
3 / 1/3 = how many time 1/3 can go into 3 right?

3 1/3s makes a 1

1/3 + 1/3 + 1/3 = 1 + 1/3 + 1/3 + 1/3 = 2 + 1/3 + 1/3 + 1/3 = 3

that's 9 1/3s so 3 / 1/3 = 9

9-9 = 0

0 + 1 = 1
so the answer is 1 right? or did i screw up

>>36342300
it goes from left to right idiot, addition and subtraction are the same level, addition doesn't come first...

>>36342329
Then state the answer if you're so tough, OP. Wouldn't want to be a brainlet now would we?

>>36341972

you do the division first because there are no parentheses or multiplication.

It is vague, because there is no answer proposed by the source.

Arithmetic is to numbers what semantics is to communication. The first (arithmetic) is artificial and subjective, a man-made interpretation of the second concept (math or numbers), which is objective.

I'd dock your pay as principal.

Suppose I wanna do 1 + 2X, where X is some number. Well 1+2X = 1 + 2 * X and it makes perfect sense to make multiplication go first. If we do from right to left we be fucked, 1+2*X will be 3X, ridiculous. In fact, addition will not commute with multiplication, and were gonna have a field day resolving this (field-geddit?

>>36342980
Wrong, it's nothing.
Look at the equation, it cuts off at "=". It's not a complete equation. There isn't even a space to write the answer down.

>>36343073
You're a fucking idiot. Leave.

>>36343159
I'm not wrong, only an idiot would print off an equation without enough page space to write down the answer. It's just impractical.

>>36343073
This is the correct answer.

The equation should end with

= x
find x

But it just ends at = ____________

How can we be sure that there isn't more to the equation?

Agreed comrade, perhaps this was secretly an algebra equation and OP is shortchanging us?

>>36343196
>How can we be sure that there isn't more to the equation?

You're free to answer it by writing "...=3-2" or something like that, it's also perfectly valid. But regardless of what you do, the value you end up with on that side has to be 1, because that's literally what EQUATION means. There isn't any other answer, there's just many different roundabout ways you could express that answer.

>>36341428
It's 1, but I see the confusion. Just put into a calculator 9-3 divided by (1 divided by 3) +1

The 1/3 isn't really an irrational number, but an operation. From there on, since there are no brackets, you just go from left to right. If you do this, the answer is 1. I see why people get answers like -1 though, some schools teach that addition always comes first with no brackets.

>>36343073
>>36343196
Please be bait.

>>36343196
Equations are literally expressions that equate to a number. You don't need an equals sign, it still means 1.

>>36343289
This. It's basically a dick move to write the question this way. Firstly, brackets should be used, although the lack of brackets just means to go left to right in this case.

But 1/3 could be perceived as an irrational number and not an operation.

>>36343191
Write on the bottom faggot. Then leave.

>>36343289
How? It's like you can't even do this.
9-3/(1/3)+1
Since it's one-third you just ask yourself how many times one-third goes into three. It's nine, then subtract it from nine which is zero. Then add one to nothing, which is one. Are you guys fucking using fairy math? Wherever you learned this shit, you got gimped as fuck.

Here's a visual representation:

>writing the answer below the equation instead of next to the "=" sign
Back in my day this was a sign of brain deficiency, you wrote your work below the equation and then wrote the answer next to the "=" with a circle. Your methods are inferior.

Ok all you self perceived geniuses that think you are smart because you can do simple maths, come and tackle a harder problem >>36343616

>>36343676
Your lovic is inferior. If you can't solve the equation admit it. If not leave. We don't want you lecturing the format of the image. If it really bothers you that much, fix it.

>>36343743
It is not my problem to fix brother, it is OP's. Their inferior formatting is an eyesore to any practical thinker of the math community. It ails everybody in this thread, right down to the paragraph demanding an answer nobody can agree on. This is one of the many issues that common core has wrought upon American education as well, a logical question but a poor execution.

No wonder you're a brainlet, buying into OP's poorly-constructed machinations. I encourage you to do further outside of the box thinking before you become enslaved to yet another endless struggle.

Why did you do 9 divided by 1/3? You do the subtraction first. Where is the plus one? The equation is not equal to 9-3.

This is the most wrong answer I've seen so far. Not even just wrong order of operations, but completely wrong ordering entirely. 9-3 comes first. And you ignored the 1 completely. Fucking Hell go back to school...

can someone explain why order of operations work. it seems like an arbitrary set of rules everyone agreed upon. but how does the answer you get mean that it is correct??

>>36344381
LEFT TO FUCKING RIGHT******

sorry

>>36344034
If you know what factorials are, you should be able to deduce that. It's not exactly magic.

>>36341428
Whoever thinks PEDMAS puts division ahead of multiplication is retarded
Parentheses first, then exponentiation, then implicit multiplication (when its a number next to parentheses or variable) then you go from left to right doing divisions and multiplication in the order they appear, the you go from left to right doing addition and subtraction as they appear.
When you have a fraction bar, you do the operations above and below before you divide, like parentheses
This is not hard.

>>36344393
You're exactly right, they are arbitrary rules we agree on.
Assuming the photo also follows these arbitrary rules, that expression equals 1. There is no reason to assume it doesn't.
The expression is ambiguous though, and fuck whoever made that picture.
Is reading an english sentence from right to left "wrong"? Probably, since we agree to read from left to right, but if someone wrote their sentence from right to left then it would be correct. However, since we agree to write from left to right, we are inclined to assume that was the intent, unless otherwise specified.

>>36344381
That's just pedmas without the brainlet mnemonic (plus the modulus operator)

>>36344393
Oh also the reason we use pedmas is due to properties like associativity and commutativity, it's pretty much the most flexible way to write expressions

>>36341847
If there's any hint of ambiguity, add brackets. It's a small effort and makes every formula better.

>>36344669
>>36344669
but what if there is a kink in the rules and everyone has been getting the wrong answers all along. who is to say 19 isnt right though. that the part that i cant figure out. i understand the properties they are used outside of using pemdas. idk what i want anymore.

>>36344995
The expression in the photo, under the current conventions agreed upon in society, is equivalent to 1. It's another way of writing one, it's all convention. If the person who made photo said "btw evaluate from left to right" then it would equal something else. This isn't God, this is just us making our scribbles consistent. It's somewhat divorced from the actual numbers but without the standards it would be a real pain in the ass to do math.

>>36344995
Another way to think of it is that the expression doesn't "equal" one, it's not the "correct" answer. It's defined to be one. Sure if you evaluate the expression differently it isn't one, but it's important to have this convention to do math efficiently. If you wanted to make it equal something different, use parentheses, which is another convenience afforded to us by our notation

>>36341428
9-3/(1/3)+1=9-3*3+1=9-9+1=0+1=1

>>36344034
Factorials are just shorthand for long mulitplications.
Logs are functions and the argument should be seen as having a set of parentheses around it.

If we are gonna use obvious mathematical steps in resolving this:
1) 3 / 1/3 is 9 because we turn 1/3 upside down to turn the division to multiplication so it's gonna be 3 x 3 which is 9
2)9-9 is 0,easy shit
And lastly 3) 0+1=1
I don't understand why are you saying that people didn't understand this problem.
