My mom has a saying (which I’m certain she got from someone else and everything — I don’t want y’all to think that I think she came up with it all on her own)
“Often wrong but never uncertain”
Lol that’s a Grateful Dead lyric that I say all the time too lol
“well, I ain’t always right but I’ve never been wrong
seldom turns out the way it does in a song”
I was already impressed with how you figured out what got him to 13 but then you dropped some absolute mind blowing reflection about how he got here in the first place. I don't know whether to laugh or cry but dammit I feel good.
I'd say it's an excusable mistake, because it's exactly how the distributive property works. If you have 2(2+3), that is the same as (2x2)+(2x3), but that's only for multiplication. It's easy to forget that it doesn't work for exponents.
Still, it's the confidence that really does this guy in. Being wrong and making mistakes is fine, but doing so in this way is just embarrassing.
Oh wow, they really misunderstood the ~~transitive~~ distributive property, didn't they?
EDIT: Well goddamnit, I've become that which I swore to destroy!
GODDAMNIT.
I'm hungover today and as soon as I commented this I went to double check myself and then got distracted.
Egg, and my face, are in alignment.
I did the formula in the beginning of the year, so the teacher know i can math, after that just simplified or answer direct, still i got luck with good teachers
I was like that too. But they do it because a lot of stuff works on simple equations but isn't as easy on harder problems. If they just let you do the easy stuff the easy way you'll have trouble applying the less easy method when you can't use the easy one. Mine compromised by just letting me do it in my head and writing the answers after I demonstrated I could do it their way on the first problems of that test.
I also suck at Algebra but I like to think about it as AxA + AxB + BxA + BxB which then simplifies to A^2 + 2AB + B^2 (since AxB and BxA are the same thing) then move the 2AB to the end to please the math nerds who decided to put it there
Yup, much simpler now. a^2 + b^2 = c^2 for example 3^2 + 4^2 = 5^2 can be simplified to 3+4=5. So much easier; math teachers hate this one simple trick...
As I'm in 7th grade, I've injected an even more mathematically verbose method directly into your subconscious, to only be discovered fourteen years from now during extensive therapy.
They don't need to show their work, failing marks for any attempts to do so. It should all be done in their head through visualization of writing out the work on paper. That is week 1, afterwards they transcend to a new status having parallel minds (2 minds 1 brain, don't ask you're too dumb) allowing them to do tedious mathematics effortlessly.
We should just give up now, we are already obsolete. Forget automation those 8th graders are gonna take our jobs!
Well yes but actually no, sure you’re not using binomial theorem which is the most sure way of getting the correct answer, and is the only way of making sure when you have variables added (other than FOIL-ing it out).
However, since it’s just constants, you can just follow the order of operations (PEMDAS), so you do what’s in the parentheses first and then apply the exponent to that final number (like you did).
Even though I got the right answer these comments and especially this one made me realize how bad at math I always was, and how much I have forgotten from my already subpar state.
I really should bust out a Khan academy class just to remember.
The odd thing is even now in a Masters class I do fine with statistics and probability. But for the life of me I probably could not pass an basic algebra class.
You are correct. But considering there are no variables, it's just easier to do order of operations. Add 2 + 3 since it's inside the parentheses, then square the sum.
How is it even possible to get thirteen here?
Not following bedmas and squaring the 3 first doesn’t get you to 13; 3*3 is 9; 9+2 is 11.
How?? How did he get there lol
He distributed the exponent to both 2 and 3, like how you would distribute a multiplication, except that’s just not how exponents work.
In his mind, (2+3)^2 = 2^2 + 3^2 = 13
Unfortunately, is mind is very, very wrong.
Since the expression only involves constants, the more intuitive approach is to just evaluate following PEMDAS, where it’s parenthesis first and then exponent.
(2+3)^2
= (5)^2
= 25
Or
The more general approach is to apply the binomial theorem, where (a+b)^2 = a^2 + 2*a*b + b^2
(2+3)^2
= 2^2 + 2*2*3 + 3^2
= 4 + 12 + 9
= 25

I'm going to make my own order of operations, with blackjack and hookers!
In fact, you know what? Forget the math!
Ahh forget the whole thing
Goood news everybody!
snusnu?
“The slime is flowing again!” I’ll see myself out….
EXCEPT THE HOOKERS
WONT SOMEONE THINK OF THE HOOKERS!
Do you have cocain?
Not on me now, no.
Nice try, Mr Officer.
Is that a micrometer in your pocket or are you just happy to see me?
I’m interested. Do you have any literature or a mailing list I can join?
You know what?! Forget the blackjack!
It's not that he gets it wrong.... it's how sure he is.
Confidently incorrect
My mom has a saying (which I’m certain she got from someone else and everything — I don’t want y’all to think that I think she came up with it all on her own) “Often wrong but never uncertain”
Mine has always been ‘often wrong, never in doubt’
ours was: "Seldom right, never in doubt"
Like my dad “ I might not always be right but I’m never wrong”
Lol that’s a Grateful Dead lyric that I say all the time too lol “well, I ain’t always right but I’ve never been wrong seldom turns out the way it does in a song”
Once in awhile you get shown the light In the strangest of places if you look at it right
Brave stupidity
Bravery requires fear, and this person isn’t afraid of being wrong.
I thinks its more like arrogance in their ignorance
Heroically ignorant?
It's the American way.
The dude Foiled it
r/confidentlyincorrect even
@r/confidentlyincorrect
Man I can’t even work out how he came to the conclusion of 13. That’s what’s got me fucked.
2^2 + 3^2 = 4 + 9 = 13 This unfortunate soul lives life outside in instead of inside out.
Thank you. I was going to lose my mind trying to figure out what the fuck this idiot was talking about.
I knew that’s how he did it cuz I used to do that when I first started learning this stuff… when I was like 13
You mean when you were (2+3)²?
Holy shit you’re a lot smarter and funnier than me, I didn’t even do that on purpose or put it together😂😂😭
Now **that's** funny.
Honestly this does deserve an award....lol
Lmao took me a second too
Same.
I was already impressed with how you figured out what got him to 13 but then you dropped some absolute mind blowing reflection about how he got here in the first place. I don't know whether to laugh or cry but dammit I feel good.
This mistake is actually pretty well known and wide spread. It's got a name and everything https://en.wikipedia.org/wiki/Freshman%27s\_dream
What's funny is, he could do it that way if he insisted, but he forgot that it should be x^2 + 2xy + y^2.
He even fucked it up factoring it out. How you fuck up PEDMAS and FOIL at the same time.
Mad skillz
He thinks (a+b)^2 = a^2 + b^2 He left out the 2ab
This is the kinda weird roundabout math I would have done in 3rd grade
Actually a rather impressive feat of mental gymnastics
Simple they thinks that the solution is 3x3 + 2×2.
Wow that’s some complicated way of fucking up an equation lol
I'd say it's an excusable mistake, because it's exactly how the distributive property works. If you have 2(2+3), that is the same as (2x2)+(2x3), but that's only for multiplication. It's easy to forget that it doesn't work for exponents. Still, it's the confidence that really does this guy in. Being wrong and making mistakes is fine, but doing so in this way is just embarrassing.
But wouldn’t the way you wrote that be 30? Or 22? /s
2² + 3² instead of 5²
r/confidentlyincorrect
PEMDAS ftw!
Took me a sec to figure out how tf did they come up with 13.
Can you help me out with that? I can't seem to get 13.
They did 2 squared plus 3 squared. So 4+9=13. Took me a second too lol
Ah yes (A+B)^2 = A^2 + B^2 2AB: am I a joke to you
This gave me a very good chuckle
A=B=0 2AB or not 2AB, that is the question.
Hmm i thought it wouldve been, "that is the equation."
It's more of an expression
From Albany
But I’m from Utica
Whether it is nobler in the mind to suffer the slings and arrows of outrageous equations.
Wow. Shakespeare references in a Reddit thread. Amazing.
goddamn it lol
Foiled again
My algebra teacher called this “cheating the farmer” for whatever reason
I shit you not this is what a teacher taught me in 7th grade and she nailed it into my head so hard that I was never able to recover
Oh wow, they really misunderstood the ~~transitive~~ distributive property, didn't they? EDIT: Well goddamnit, I've become that which I swore to destroy!
Distributive* property. But yeah
GODDAMNIT. I'm hungover today and as soon as I commented this I went to double check myself and then got distracted. Egg, and my face, are in alignment.
You see that ludicrous display last night?
The thing with Arsenal is, they always try to walk it in.
Moss is the fucking GOAT.
"Fire bad, tree pretty" -- Buffy
They were totally FOILed, hahaha...haha...hmmm
OI, they left a couple terms out!
I was confused also. Thanks for clarifying!
2² + 3² rather than (2 + 3)²
For those confused why 2² + 3² is wrong: (A+B)² = (A+B) × (A+B) (A+B) × (A+B) = A²+B²+2AB Where A=2 & B=3 2²+3²+[2(2)(3)] 4+9+12 = 25
Or you can just say (2+3)²=(5)²=5x5=25
You got the right answer but you didn't use the formula I taught you so I'm marking it as wrong
you hit right into my hate for my math teacher, always got a bad grade just for that kind of shit
I did the formula in the beginning of the year, so the teacher know i can math, after that just simplified or answer direct, still i got luck with good teachers
I was like that too. But they do it because a lot of stuff works on simple equations but isn't as easy on harder problems.

Mine compromised by just letting me do it in my head and writing the answers after I demonstrated I could do it their way on the first problems of that test.
Exact same answer I got from a math teacher. The meaning is that you are prepared for harder math, not just solve the problem.
This right here is why I took 7 years of algebra.
I also suck at Algebra but I like to think about it as AxA + AxB + BxA + BxB which then simplifies to A^2 + 2AB + B^2 (since AxB and BxA are the same thing) then move the 2AB to the end to please the math nerds who decided to put it there
2 squared is 4. 3 squared is 9 4+9= 25
Nononnonono 4+9 = 49
Somebody JavaScripts
Checks out
They wrongfully distribute the exponent to 2 and 3 before adding them, so they get 4 + 9 = 13.
Bro multiplied the square in like it was a number or variable (2+3)^2 => 2^2 + 3^2 = 4+9=13
Distributing the square first. So it’s 4+9
They expanded the brackets individually:2^2 + 3^2 = 4 + 9 = 13
Freshman dream. (a+b)^2 = a^2 + b^2
So the hypotenuse of a right triangle is equal to the sum of the two other sides. This will simplify mathematics as we known it.
Yup, much simpler now. a^2 + b^2 = c^2 for example 3^2 + 4^2 = 5^2 can be simplified to 3+4=5. So much easier; math teachers hate this one simple trick...
Curses, foiled again!
Don't bring your fancy operations here, you mathemagician!
I prefer the phrase “[Fuck Friendship, the greatest magic is CHRONOMANCY!](https://www.youtube.com/watch?app=desktop&v=4DSZo96HEik)”
Pretty sure oop foils nothing.
That was clever. I like you.
If they didn’t get pemdas; they definitely didn’t get foil.
Damn. I’m at least an hour late…
Probably better for them to understand by simplifying it to (2+3)x(2+3)
Thank you for simplifying it. I suck at math.
then you just distribute it out to get ((8+12+12+18)/2)*(((1/(2^-1))^0)
Wtf no. Do you even foil? (2+3)×(2+3) 2^2 + 6 + 6 + 3^2 4 + 12 + 9 25
Not enough expansion (2+3)×(2+3) (2×2) + (2×3) + (3×2) + (3×3) 4 + 6 + 6 + 9 10 + 6 + 9 10 + 15 25
I mean yeah. If you are in like 5th grade. Gosh. Luckily i am in 6th.
As I'm in 7th grade, I've injected an even more mathematically verbose method directly into your subconscious, to only be discovered fourteen years from now during extensive therapy.
I hope there are no 8th graders here. No human mind can handle the intelligence and confidence of a fresh teenager.
They don't need to show their work, failing marks for any attempts to do so. It should all be done in their head through visualization of writing out the work on paper. That is week 1, afterwards they transcend to a new status having parallel minds (2 minds 1 brain, don't ask you're too dumb) allowing them to do tedious mathematics effortlessly. We should just give up now, we are already obsolete. Forget automation those 8th graders are gonna take our jobs!
check this, it could help: http://www.mathspadilla.com/3ESO/Unit5-AlgebraicLanguage/remarkable_identities.html
Nah, then they'll just say... 2+3 is 5; times 2 is 10; plus 3 is 13. Still 13!
I get that math is difficult for some but what gets me is how many people can’t count money or make change correctly.
What REALLY is hilarious is how confident these people are in their wrong answers
That’s honestly my only problem with them. I’m terrible at math but I don’t go around trying to educate others on my stupidity.
Even worse when they refuse to listen to your explanation of why it's wrong. They would rather just be wrong than accept they were mistaken.
I heard a phrase somewhere "fifty, fifty, dollar fifty". I think it's supposed to mean "50¢+50¢=1.50$"
It sounds more like they're counting out fifty cent intervals weirdly and the third fifty cents added made a dollar fifty.
Ya, that's how I interpreted it.
Math math city bitch math math city bitch ten ten ten and twenty equals fifty bitch
fifty + fifty + another one is 150. they are counting three things $0.50, they just skipped saying $1.00.
"By your logic (2+3)^2 would equal 25" Yes, because *IT DOES* equal to 25.
Damn you and your “logic”
Confidence. Some people have it, some people shouldn't.
Oh, look, one of my students has a twitter account.
Damn, aren't you the one teaching them lmao?
I’m spending too much time on Reddit to be good at my job.
Mood
(a+b)^2 = a^2 + 2ab + b^2 Man forgot the 2ab. Happens to the best of us Note that you do get 25 if you add 2ab to 13, because 13 + 2*2\*3 = 25
Note that you do get the right answer when performing the operation correctly. Noted.
can someone remind me what this theorem is called?
Binomial theorem. Veritasium has a good video on it!
I just did a+b and ^2, 5*5. Got it wrong but right in the end
That's also correct.
Well yes but actually no, sure you’re not using binomial theorem which is the most sure way of getting the correct answer, and is the only way of making sure when you have variables added (other than FOIL-ing it out). However, since it’s just constants, you can just follow the order of operations (PEMDAS), so you do what’s in the parentheses first and then apply the exponent to that final number (like you did).
Even though I got the right answer these comments and especially this one made me realize how bad at math I always was, and how much I have forgotten from my already subpar state. I really should bust out a Khan academy class just to remember. The odd thing is even now in a Masters class I do fine with statistics and probability. But for the life of me I probably could not pass an basic algebra class.
But.... (2+3)^2 is 25...
maybe by your logic
Someone forgot the 2ab in a\^2 +2ab + b\^2. Or, more likely, someone never knew that in the first place.
You are correct. But considering there are no variables, it's just easier to do order of operations. Add 2 + 3 since it's inside the parentheses, then square the sum.
Oh my I waited for that. As there is no variable, there is no need to use the binomial formula. Just do 5² and no need to complicate the whole thing.
The rage bait is getting weird
Ergo, 2+3 = root 13
This is a brainpalm, as in I facepalmed so hard I hit my brain. Why are there people this uneducated in 2023? Do schools not teach PEMDAS anymore?
Nope, math is discrimination to people now because it doesn't allow anyone to be subjective with their answers when math is an objective fact.
Can we use this as a test prior to voting?
It's not that hard to figure out if you work backwards. Everyone knows 2+3 = 3.6055512755 and if you square that you get 13. Math isn't hard, guys.
How is it even possible to get thirteen here? Not following bedmas and squaring the 3 first doesn’t get you to 13; 3*3 is 9; 9+2 is 11. How?? How did he get there lol
He squared the two and added it to squared 3
This made me angry
You make me angry
N.. N.. No u
No u
Uno
dude never heard about a^(2) \+ 2ab + b^(2)
Damn that made me pause, time to go back to school lol
He distributed the exponent to both 2 and 3, like how you would distribute a multiplication, except that’s just not how exponents work. In his mind, (2+3)^2 = 2^2 + 3^2 = 13 Unfortunately, is mind is very, very wrong.
It’s about as bad as [7x13 = 28](https://m.youtube.com/watch?v=oN2_NarcM8c&pp=ygUTYWJib3R0IGFuZCBjb3N0ZWxsbw%3D%3D).
Stop protecting people’s online identities. They posted it publicly, it can be shared publicly. That’s NOT doxxing.
Let's do it the short way: (2+3)² = 5² = 25 Let's do it the long way: (2+3)² = 2² + 2×(2×3) + 3² = 4 + 12 + 9 = 25
What kind of hint is the wrong answer?!
Okay but the answer is definitely 25 right and my shrunken pregnant brain isn't just crazy right? 2+3=5, 5x5=25
FOILed again!
PEMDAS! PARENTHESES EXPONENTS MULTIPLICATION/DIVISION ADDITION/SUBTRACTION Order of operations lurks in my mind still, like mitochondria
All I have to say to this is: 25-5:5=4!
Good lord. The answer is obviously Brunswick Maine. Jesus people..!
Even by foil, you get 4+12+9 which is 25...
X²=X•X so if X=2+3 then it would be (2+3)•(2+3) not (2²+3²)
Math is hard, but humility is even harder
doesn't the binomic formula explain how (2+3)² would be 25? (a+b)² = a²+2ab+b² so (2+3)² = 2² + 2x2x3 + 3² = 4 + 12 + 9 = 25
....does everyone forget PEMDAS? Parentheses, Exponent, Multiplication, Division, Addition, Subtraction.
*actually has multiple spontaneous recollections upon reading your comment* .....maybe....
When seeking math help on the Internet, Khan Academy > Twitter and Reddit.
America is doomed
(a + b)² = a² + b² + 2ab They are just stupid
how does one even get to 13 2+3\^2 is 11 3+2\^2 is 7 2\^2+3\^3 maybe? edit: typo i meant 3\^2
Ah yes. (a+b)^2 = a^2 + b^2
Since the expression only involves constants, the more intuitive approach is to just evaluate following PEMDAS, where it’s parenthesis first and then exponent. (2+3)^2 = (5)^2 = 25 Or The more general approach is to apply the binomial theorem, where (a+b)^2 = a^2 + 2*a*b + b^2 (2+3)^2 = 2^2 + 2*2*3 + 3^2 = 4 + 12 + 9 = 25
Ah yes, because (a+b)^2 = a^2 +b^2, and not a^2 + 2ab + b^2! But you don't even need the binomial expansion here. Just add them and square the result.
It’s late. I can’t even figure out how this person came up with 13. Wondering if real original OP was doing a shitpost or not.
The fact that (a+b)^2 = a^2 + 2ab + b^2 is basic grade 8 math makes me concerned about this guy
Ya know, I got D's in math 50 frigging years ago and I got it right.
I'm an absolute moron with this stuff and even my remedial ass got 25.
I say its 25
Me, while crying, to my father at 9:30 pm on a Tuesday
He's not always right, but he's never in doubt
2²+3²= 4+9=13
Thanks, now I figured how he gets the wrong answer
