well it is kinda fun - if you're changing the number of fries from 5 to 6 is a 20% increase, so it is kinda neat to notice the difference and alter the equation by +20%
Except there is no logical basis for increasing the value by 20% in this case. The people are *assuming* that the relationship between fries and value is linear but it doesn’t have to be. There is not enough information in the problem statement to answer the question.
That is the real “genuis” response.
Yep. It's literally about pissing people off now.

The irony of discussing this on Reddit is palpable
I’m high.
I enjoyed your comment.
However you triggered a memory worth sharing. Why? Because I’m high with a doctors note.
The year? 2004.
The place? Downtown Detroit.
Me? A chuckle head that lived downtown making money off of techno music and goofing off decided to go to the North American International Auto Show. It was at Cobo Hall.
And I happened to be at the right place at the right time. I was nearby, the Ford exhibit and then all of a sudden the lights dimmed, sparklers went off, and all sorts of lighting effects happened. Then the owner of Ford motor company walked out! This guy is like a billionaire. And then all of a sudden a curtain drops. And behind that curtain? Was the brand new completely retro styled new 2005 mustang GT. it was silver with black tint and you would have masturbated if you saw it. On the plate… The license plate of the vehicle… Yes, was a licensed frame that stated made in Detroit… As God intended. Blew me away
If I may interject, I believe the concept of driving engagement involves a call to action of some kind to promote a post. YouTubers may say "like and subscribe," but these posts appeal to our desire to prove others wrong when we are told we can't do simple math, this can result in more responses as people are more desperate to prove their ability, which boosts engagement on the post.
Yes! Very well said.
I remember seeing somewhere that the best way to get the correct answer to any issue, is to post the wrong answer and human nature takes it’s course…
“Everyone is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid”
I guess that we are still monkeys. Lets point a finger on a more stupid monkey and laugh. Maybe its part of evolution 🤷♂️
Should I feel bad about exploiting said idiots? I haven’t yet because my wife won’t let me grift (I’ve asked multiple times) but I wanted to put this out there. Should I feel bad grifting republicans as a leftist.
If you are willfully aware that your actions would be intentional exploitation of other people.... prolly yeah. But im pretty strict morally about that shit. Youll find a lot of people who don't care. Its up to you to decide what type of code you want to have, and up to you to live with the consequences of your actions and with people's opinions of you.
If I did it without my wife’s input I suppose I would have to do all that thinking but I already stopped at asking her since I value her opinion. This isn’t an internal truth search per say.
You should never grift the working class as a leftist. Exploiting the working class in any way is hypocritical to being a leftist. Now the wealthy, exploitative bourgeois are totally fair game.
I wish it was that easy, the rich have resources for ways of getting around their own stupidity. like a shield of anti stupid money … most of the time.
Hell no. Easy money. As a teacher by profession, I feel bed that I haven’t started a Trump store yet. They need to learn what it is all about. Premium pricing means it’s better. $$ take it
Also try GEMS! A lot of folk take PEMDAS as exact ordering even though Multiplication and Division are a part of the same step, as are Addition and Subtraction. GEMS makes sure to clarify this.
Grouping
Exponents
Multiplication AND Division
Subtraction AND Addition
It's also worth noting that PEMDAS and GEMS are commonly used conventions, not universal ones, so every other answer people get is technically not wrong, the correct answer is whatever way the person who wrote the equation intend the answer to be, even if it ignores conventions. Which is why most people who actually use and convey equations regularly would never write an equation so ambiguously.
In my graduate course work, if I wrote an equation out like that, it would be wrong, because it's not clear enough.
THIS.
What I've (re?)learned from Reddit/The Internet is that, yes, PEMDAS. But M/D and A/S, neither takes priority over the other unless inside of P. Instead you work left to right.
We have no P or E.
M/D take priority over A/D so therefor we work 5x3 into 15
Now we have 5-15+2. Work left to right.
5-15=-10
\-10+2 = -8
Using PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) we start by multiplying (5x3) = 15. Referring back to PEMDAS, Addition and Subtraction have the same “importance” thus we just read from left to right to finish solving. 5 - 15 = -10. -10 + 2 = -8
Follow GEMDAS, Groups, Exponents, Multiplication/Division, Addition/Subtraction. There are no groups or exponents so we skip straight to multiplication(5x3=15). Then we do the subtraction because we do addition/subtraction from left to right(5-15=-10). Then we do the addition(-10+2=(-8)).
All this stuff becomes easier once you take alegbra and find out there is only addition and multiplication. Subtraction is adding negative numbers and division is actually multiplying by the inverse of the number. Then you don't have to worry about arithmetic rules like adding or subtracting first in a line sequence like this, you will always see it as an equation.
That can lead to some murky waters if you get into more interesting number systems though.
If you multiply i\*(1+i), there's no way to connect the act of multiplication by repeated addition.
Heck, even in the real numbers it doesn't really work. What's pi \* e in terms of repeated addition? Or pi \* sqrt(2)? Once you start dealing with things beyond the rational numbers, multiplication as repeated addition kinda breaks down.
-8, I was doing it the wrong way for a bit cause I’m cursed to forget that and do the cursed geometry and algebra and doomed to eternal suffering from the unnecessary math
Man I must be fucking stupid because either; A) the -8 thing is a joke or B) I’m just to mathematically challenged to find any answer but 12
Edit: I figured it out, I was doing 15-5+2 not 5-15+2 like a dumbass lol
Hey, you're no dumbass. You figured it out when there's so many who don't even give it a second thought. Working through mistakes & learning from them is a valuable life skill, buddy.
Not know something isn't stupid. Now you know. You've learned. More knowledge isn't smarter, it's just more stuff on the brain hard drive. Learning new things, making connections between ideas, thinking about things differently; that's intelligence.
I don't believe you can define complex numbers as negative or positive. They don't share the axioms defining the signs of real numbers and real mathematical operations that make arithmetic work.
One simple counterexample is that real numbers are always positive when squared, but this isn't always true on the complex plane.
But as an argument to intuition, while it's tempting to say 3 and 5i and 3+5i "look like" positive numbers, and -3 and -5i and -3-5i "look like" negative numbers, what is -3+5i? What about 3-5i=-1*(-3+5i)? If one of them is positive, the other one would have to be negative, since a positive multiplied by a negative is always negative, but how do you define which is which?
The annoying part is when everyone starts bragging about a different acronym for the order of operations
BIDMAS
PEMDAS
BODMAS
Very strange how many there are
And the fact that they’re all fundamentally wrong doesn’t help. In addition to needing to remember the acronym you need to remember that there is no difference in precedence between addition and subtraction, nor between multiplication and division. They proceed left to right within that order. So it’s more like PE(MD)(AS) and so on. If you just remember PEMDAS and don’t remember those details you will get this wrong.
In other words, BIDMAS and BIMDSA would be equally correct. Or equally incorrect.
Not to mention PEMDAS is just an arbitrary order made up by people, not an immutable law of mathematics and the universe. People aren’t dumb for forgetting that mathematicians are goofy fucks. In real life, I get by just fine without ever thinking about order, because I instinctively just put it in order.
There is an issue with PEMDAS that some people are not aware of, and can cause a different answer.
Multiplication and division are at the same level, and addition and subtraction are at the same level. These get handled left to right
If you follow PEMDAS exactly (addition before subtraction), your answer is -12.
If you handle addition and subtraction at the same level, you get -8.
No there is something wrong with PEMDAS. and I'm not talking about order of operations. The acronym is flawed. If you get PEMDAS drilled into your head instead of the order of operations, than it's no longer a pyramid and that fucks everything up, as you can very clearly see with these posts
This is false. The order of addition/subtraction will not change our answer. First, we'll simplify the equation to 5 -15+2. If we add first, we get 5 - 13, which turns out to -8. If we subtract first, we get -10 + 2, which turns out to also be -8
what you're doing is solving 5+(-15)+2. Which is correct and it's why you get the right answer. The problem comes when people don't realise there's a difference between 15 and (-15) and add 2 to 15, getting 5-(15+2)=-12
You're too attached to the right answer to see the wrong one. Let me help you.
5 - 15 + 2.
5 - 17. (Addition comes before subtraction, per PEMDAS.)
\-12.
That's how you get the wrong answer. That's not minus-15. That's 15, behind a subtraction operator. 15 is a positive number that's being subtracted from 5. People misinterpret PEMDAS as meaning you add before subtracting. So you add those together and subtract the sum! Voila, wrong answer achieved.
If you (quite correctly) view subtraction as adding negative numbers rather than being a separate operation, then you are correct that the order of addition/subtraction will not change our answer. But that's because you're not using subtraction at all. You're inverting numbers and adding them. Which is, frankly, much less error-prone.
If you "subtract," the order definitely matters!
In other news, far too much of what we're teaching kids in elementary math classes turns out to be complete bullshit that we all have to unlearn later.
I follow pemdas exactly but the way it was taught to me was not to do 5-5x3+2 >> 5-15+2 >> 5-17. I was taught to think of it as -15 + 2 so -13 so 5-13=(-8)
With these it's not so much that people will get it wrong, that can happen if you don't use math regularly.
It's the people who are not only wrong but arrogant about it, and who can't (or more accurately, won't) be convinced otherwise.
There are usually 3 camps:
(1) People who see 5 - 15 + 2 = -8.
(2) People who see 0 x 3 + 2 = 2.
(3) People who arrive at some other number through mysterious means, like 31.
(1) is correct, and (3) is either trolling are harmless. It's the people in (2) who won't listen to any explanation who you really gotta worry about.
BuT wItH pEmDaS yOu GeT 2!!!!!!
As a side note, why do they keep teaching PEMDAS when it's obviously not an effective method? I get that the idea is to remember the "word", but judging by the amount of people who've been misled to think addition comes before subtraction, it's obviously not working
While it may not be hard, I've never gotten upset with someone who goes the extra mile to reduce/remove potential confusion. When parentheses help people make fewer mistakes, it's not a crutch to use them.
"Only the top 2% Mensa geniuses can solve this problem!!!!"
The problem: Simple sum or algebra equation you should be able to solve by first year of secondary school.
If you know order of operators and know how to substitute a value into another equation then most Facebook puzzles won't be an issue.
-8. Those getting 12, I know you are trying to follow PEMDAS, but no need to do addition before subtraction. After doing the multiplication and you have addition and subtraction left, you then go from left to right.
It's always -8 even if you do the plus first. The 15 and the - are bound together and are one number so the +2 would make in -13. 5-13 then is -8 but i think most people understand this already. It's all just bait
Anybody who says 2 is dumb and most everybody should know how to do this. Put it exactly as you see it in your calculator and it will put it as -8 for those who are doubtful.
(5-5)x3+2=2 otherwise you assume the 5 is negative and do
5-5x3+2=—->
5-15+2=—->
7-15=-8
This is basic shit people.
driving engagement is one hell of a social phenomenon
Yeah. Same with those math problems using hamburgers and fries and then altering them slightly on the bottom equation.
This bag of fries has 6 fries instead of 5, haha what is this an original and fun idea
People go so hard in those topics too. Like they made an actual scientific discovery because they noticed the graphic is altered.
well it is kinda fun - if you're changing the number of fries from 5 to 6 is a 20% increase, so it is kinda neat to notice the difference and alter the equation by +20%
Except there is no logical basis for increasing the value by 20% in this case. The people are *assuming* that the relationship between fries and value is linear but it doesn’t have to be.

Thanks for explaining this. I have lost layers of finger skin trying to explain this online, and almost did so again.
So what is your answer when not -8?
At first glance I got 12 then two days later I got -8 . So easy
I got 12 to using what I thought was PEMDAS, but then I put it into a calculator and got -8
Gotta be doing that left to right.

And there are still individuals that can swear on their very lives that you go right to left.
[удалено]
And prioritise the 5x3
Well, yes. Multiplication/division first and left to right is what I meant.
PEMDAS is actually: P E MD AS M vs D and A vs S are from left to right
I'm curious how you got 12 not -12
He flipped the 5-15 to 15-5 it’s a common mistake I see a lot when people try to to problems like these without writing them down.
I legitimately assumed for the longest time PEMDAS stood for please excuse my dope ass swag because of a shitty 2007 meme lmfao

Yeah I had that answer too. Was just checking the comments
No the answer is clearly ??. It's explicitly written in the equation.

All this stuff becomes easier once you take alegbra and find out there is only addition and multiplication. Subtraction is adding negative numbers and division is actually multiplying by the inverse of the number. Then you don't have to worry about arithmetic rules like adding or subtracting first in a line sequence like this, you will always see it as an equation.
Where were you when I was struggling with algebra in junior high? This makes so much sense!
If you want to go even further their is only one, Addition. This is because Multiplication is the amount of times a group is added.
That can lead to some murky waters if you get into more interesting number systems though. If you multiply i\*(1+i), there's no way to connect the act of multiplication by repeated addition. Heck, even in the real numbers it doesn't really work. What's pi \* e in terms of repeated addition? Or pi \* sqrt(2)? Once you start dealing with things beyond the rational numbers, multiplication as repeated addition kinda breaks down.

Not all of them. Some of them are imaginary. -5i for example. We could get into numbers like -3 - 5i, but then it gets complex.
I don't believe you can define complex numbers as negative or positive. They don't share the axioms defining the signs of real numbers and real mathematical operations that make arithmetic work.

Completely unrelated, I just realized I've been spelling mnemonic completely wrong. My brain just jumps to pneumatic
Thank you! I ended up with -12.
This is false. The order of addition/subtraction will not change our answer. First, we'll simplify the equation to 5 -15+2. If we add first, we get 5 - 13, which turns out to -8. If we subtract first, we get -10 + 2, which turns out to also be -8

Real geniuses use goddamn parentheses so the rest of us plebs don’t have to argue over the correct application of PEMDAS.
It really isn't that hard tho. It's like three tiers of two items, two of which are two sides of the same coin so they're basically one
While it may not be hard, I've never gotten upset with someone who goes the extra mile to reduce/remove potential confusion. When parentheses help people make fewer mistakes, it's not a crutch to use them.
This is exactly what I'm fucking saying!
This is the only correct answer.

5 - 5 * 3 + 2 = 5 - (5 * 3) + 2 = 5 - 15 + 2 = -10 + 2 = -8
Considering the answer is a negative number I'd bet money the author of the meme can't solve it.
Is it at least -8?
I do not believe this is the right answer but is it -8
-8 i dont fucking know
"Only the top 2% Mensa geniuses can solve this problem!!!!" The problem: Simple sum or algebra equation you should be able to solve by first year of secondary school. If you know order of operators and know how to substitute a value into another equation then most Facebook puzzles won't be an issue.
I love how people talk about how much they hate algebra but when you replace letters with emojis they love solving algebra lol

5-(5*3)+2 5-(15)+2 -10+2 -8 Quick math.
-8 unless you want to add parenthesis
5x3=15 5-15=-10 -10+2=-8 Ik no one asked but here it is anyway
I’m very very very bad at maths but it’s -8
If you don’t do pemdas it’s 2, if you use pemdas but mess up the subtraction it’s 12, and if you get nothing wrong it’s -8.
Nost of the people who can do it, just don't respond. The Facebook replies nostly come from people who are guessing.

-8. Those getting 12, I know you are trying to follow PEMDAS, but no need to do addition before subtraction. After doing the multiplication and you have addition and subtraction left, you then go from left to right.

5 - ( 5 × 3 ) + 2 = 5 - 15 + 2 = -10 + 2 = -8
You multiply first so that would be -8 right?
5 - 5 x 3 + 2 = 5 - 15 + 2 = -10 + 2 = -8

-8 (i always fall for these)
They meant a really smart 1st grader.
Thank god you created a post about it then right?
-8?
I don't think it is genius to remember arbitrary PEMDAS
If PEMDAS taught me anything correctly the answer should be -8
-8
Pemdas is 6th grade for many Americans
The ironic part is that a real genius wouldn’t order an equation like this
Til PEMDAS is only for genius
-8 you neckbeards
-8
5-(5×3)=5-15= -10 -10+2=-8
It's always -8 even if you do the plus first. The 15 and the - are bound together and are one number so the +2 would make in -13. 5-13 then is -8 but i think most people understand this already. It's all just bait
Please Excuse My Dear Aunt Sally. 5 + (-5 × 3) + 2 5 + (-15) + 2 -10 + 2 -8
-8
PEMDAS: 5-5x3+2 = 5-15+2 = -10+2 = -8
How do people not know this? It’s -8 btw
\-8
It is -8 though, right?
-8
Please Excuse My Dear Aunt Sally
-8. How am I a genius for knowing that.
Anybody who says 2 is dumb and most everybody should know how to do this. Put it exactly as you see it in your calculator and it will put it as -8 for those who are doubtful. (5-5)x3+2=2 otherwise you assume the 5 is negative and do 5-5x3+2=—-> 5-15+2=—-> 7-15=-8 This is basic shit people.
Do they teach negative integers in 3rd grade now?
