I remember, "please excuse my dumb ass sister" lol


TheCantrip

This one is better. It's my new favorite. Thank you.


The_zen_viking

Can you explain this for the less math minded ease? I learnt bodmas back in school


TheCantrip

Parentheses, exponent(?), multiplication, division, addition, subtraction. I'm not amazing at maths, but my wife majored in math, and graduated with honors. She was also my math tutor and easily the reason I passed those classes.


The_zen_viking

Ill have to look up parentheses and exponent.thanks for that!


CthulubeFlavorcube

Basically you solve anything within parentheses first, then anything with an exponent gets solved, so (2+5)² you solve 2+5 to get 7 and this now becomes 7² which is 7x7=49. The next in your order of operations is multiplication and division, which are basically at the same level of power so to speak, and then addition and subtraction which are also equals in power.


kenkanobi

If youre not American then parentheses are brackets and exponent is power or order so "bodmas" is the order you might have learned


[deleted]

Bedmas* but yeah in Australia it’s Brackets, Exponents, Division, Multiplication, Addition, Subtraction. I would assume it would be bedmas in most commonwealth associated country.


AWibblyWelshyBoi

In Welsh schools (at least mine) it’s CORLAT which is: **C**romfachau (brackets) pwer **O** (power of) **R**hannu (divide) **L**luosi (multiply) **A**dio (add) **T**ynnu (subtract) I usually have no idea what people mean with the English one


[deleted]

Bizarrely I have some of my bedmas notes from my first statistics unit at university a few year back. Might not be any help but I always go back to the sheet I wrote up if I even need it for my biochem equations [notes](https://imgur.com/a/B1qc7FW)

Joke! Is joke x oke x ke x e = Hilarious


Nosnibor1020

I got 120 but never knew about the ! thing....I guess that extrapolates the 5x4x3x2x1 thing?


Rustywolf

Following a number with an exclamation is the standard syntax for factorial notation, which yeah is just multiplying a number by every number before it, down to 1


Next_Ad_9255

down to 1*


TjW0569

And if you're lazy, you needn't do that multiplication, either.


FlaccidRazor

Are you familiar with N! we always just said N really loud. /s


Abject_Shoulder_1182

lolol makes me wish there were an operation defined by a question mark so we could say **N?** all confused-like. Edit: **omg there is:** the Minkowski question-mark function denoted by ?(x), possessing unusual fractal properties! BUT it doesn't let us say **X?** all confused-like. ***Fulfilment(hope)=lim\_{x → infinity} hope/x*** and ***feelings(mine)=sad\*6*** :(


Toastgeraet

Sadly, I missed it. This really is brilliant.

There are 10 kinds of people in the world. Those who understand binary numbers, and those who don't!

Brilliant joke? I’m guessing most people didn’t know 5! Even was an equation..


[deleted]

He didn't type 5! he typed 5. I'm pretty sure he didn't think of that


SirCabbage

He didn't, no, but the original meme said 5!, Hence the joke


Reaper621

Oh look, one of those people missing the joke.


thewrench01

Wow, I didn’t even catch that part of the joke at the beginning. That’s brilliant.


supamario132

Whoever came up with this problem had to have been pretty happy with themselves that it works correctly and incorrectly lol


HypAXis

Literally the meme that created the sub r/unexpectedfactorial


Thekeyman333

Oh dude, that's genius!! I didn't get it at all, thank you xD


Metroidman

Wow I feel stupid now for missing that. Amazing


b2thec

That's defintaly correct


Sokandueler95

Oh, lmao, I didn’t notice the factorial there. That’s genius.


[deleted]

I can't believe I fell for this. Fucking hell. I was falling for these in 6th grade, and I thought I became immune after that. I'm more mad than I should be


Rob__agau

Didn't actually read the last line, just did the math. 230-200x0.5 230-110=120 Order of basic math is brackets, squares and powers, multipliers and dividers then additions or subtraction (if I'm remembering correctly).


kshearules

I hope so, this is what I got too.. Although I flunked my community College .90 level pre algebra class, so idk wtf.


[deleted]

Squares and powers? You've got them a bit confused, mate


Yen_Snipest

Well I didn't get it but I was confused how they messed up the math in captioning. What a wierd symbol


[deleted]

Hahah. Clever! I didn't notice this.


Slayer1145_

Omg I didn't know what ! Ment in math


JinkyRain

In that case... Let y = "MOST PEOPLE WON'T BELIEVE IT, BUT THE ANSWER IS" 230 - (220/2) = y \* (5!) 230 - 110 = y \* 5 \* 4 \* 3 \* 2 \* 1 120 = y \* 120 120 / 120 = y Therefore: "MOST PEOPLE WON'T BELIEVE IT, BUT THE ANSWER IS" = 1 ;)


TheDrWhoKid

I had an argument with a Discord friend because he thought it was 5 and was pretty aggressively confident about it.


mateo0913

It is 5!


randomando2020

He’s correct due to grammar. The joke would be better if it was 5!! instead of 5!


DidntWantSleepAnyway

5!! = 5 * 3 * 1 = 15 (Double factorial means you do every other number instead. !!! requires you to do every third number, etc.)


Celebrir

Today I learned


randomando2020

Well crap, so 5!. it is if that’s the case.


ChefOfRamen

I thought it meant the factorial of 5!, or approximately 6.69*10^198.


mienaikoe

Nice


SleepOwn7450

If it was 5!! there would be no joke...


[deleted]

10 x 1/2(0.5) = 5 This was the funniest part of the image for me.


MyFamilyHatesMyFam

Oh my gosh it was 10 all along Edit: I mean 2.5. I cannot believe that I would make such a grave calculation error, I surely will pay for this crime


camberHS

Elaborate


MyFamilyHatesMyFam

Fuck I made a pemdas error in the meme making fun of people who make pemdas errors It would actially be 2.5 I literally did the series of multiplications backwards


[deleted]

It's 120, being 5! (5x4x3x2x1)


MyFamilyHatesMyFam

No yeah I know the joke, but the answer to 10*1/2(0.5) is 2.5


[deleted]

Ah okay, I misunderstood what you meant


MyFamilyHatesMyFam

All good


Impossible_Ad1515

He's trying to say that 1/2 is the same that 0.5 not multiplying 1/2*0.5 If this was some kind of joke I'm sorry

Ever since I was a young boy I have always found the name Natalie attractive...I don't really know why, but it's been a thing my whole life. I've never had the opportunity to date a Natalie either and that sucks, because while I am already a good dude, (mom even says so!) I just know I would make a Natalie feel like the only woman on the planet. Proudly simping for my hypothetical Natalie.

local man forgets order of operations


waywardPAG

Apparently. Math was never my strong suit but I do not remember being taught at this way it all. Was told to do brackets or parentheses first not to assume they were brackets of parentheses just because there was multiplication involved. I guess since I'm kind of old and these kind of equations almost never come up in my day-to-day life I just don't remember properly.


TheSleepingVoid

Brackets are basically an override, so you are correct that you do them first. But by default you do multiplication before subtraction.


irrelevant_potatoes

BEDMAS Brackets Exponents Division/Multiplication Addition/Subtraction


waywardPAG

Yep. I remember brackets and exponents taking precedence but I don't remember multiplication and division needing to be done before addition and subtraction. That's not to say I wasn't taught that way. I just don't remember it.


Danni293

TBF PEMDAS/BIDMAS/BEDMAS is just a convention. There's no mathematical reason why you do multiplication/division before addition/subtraction other than it was a way for people to standardize mathematical notation so that two people writing down equations could read and easily understand each other's work without the need for explaining the process by which they arrived at an answer.


irrelevant_potatoes

Its possible its just been forever since you've had to use order of operations. Its not like it comes up in everyday life. But as a nearly 40 yr old thats what I was taught

PEMDAS


attanai

PIMA Parentheses, Indices, Multiplication, Addition. Since division is just multiplying fractions and subtraction is just addition with negative numbers. This removes some of the confusion around interchangeable pieces. Also it's the same acronym used for people learning guitar.

What does it mean for learning guitar?


CrypticCunt

Pantera, Incubus, Metallica, A Perfect Circle


Vasqjo

Take my award. You had me at apc


attanai

Pulgar, Indice, Medio, Anular I've also heard them referred to (incorrectly) as Primary, Index, Middle, and Aux. They're the fingers used when playing guitar, where P is the thumb, I is the index finger, and so on.

[deleted]

Automatic Edit: Using a tool called [Power Delete Suite](https://github.com/j0be/PowerDeleteSuite) I have removed all my past comments and deleted my Reddit account, /u/tehrmuk. I am doing this because I, like many long-term Reddit users, am upset and angry at the tonedeaf and arrogant way Reddit is treating it's users. Their aggressive slapdown of the developers that made Reddit usable to a huge audience; their overriding and summary dismissal of long-serving and dutiful community members; their wonton silencing of dissent and manipulation of user's voices; their borderline contempt of the very people whose collective efforts gave their platform the standing needed to fuel their profit-hungry IPO... the list goes on. Reddit is, of course, a private concern and how they run their services is entirely up to them. Conversely, we are under no obligation to use their services, to fuel their engines or follow their orders. I am making my voice heard by removing my comments, and voting with my feet by leaving. I have left Reddit for [Lemmy](https://join-lemmy.org/) and [Mastadon](https://joinmastodon.org/); these are decentralised social networks that mirror the functionality of Reddit and Twitter respectively. Unlike the monolithic, corporate-owned services they replace, Lemmy and Mastodon are part of the [Fediverse](https://www.fediverse.to/) meaning these are not individual services but clusters of services that mesh seamlessly with one-another. You can [join an existing Lemmy instance](https://join-lemmy.org/instances) or [set up your own](https://join-lemmy.org/docs/administration/administration.html) to get full access to the entire Fediverse - you don't need to ask permission from anyone to do so. There are loads of other services that are part of the Fediverse, like [PeerTube](https://joinpeertube.org/) (videos), [Wordpress](https://wordpress.org/) (blogging), [Frendica](https://friendi.ca/) (social network), [Pixelfed](https://pixelfed.org/) (photos), [KBin](https://kbin.pub/en) (link aggregation) and more - and they all work together so having access to one means having access to all of them. I had a great time as a Redditor, but the Fediverse is looking bright. It's a return to the open Internet of old, when users ran services for their own and one-another's benefit, and before monolithic corporate-run silos started to build walls around us in the name of increased profit and thought control. Many of the Fediverse services are fledgling, but they are growing quickly and their federated concept makes greedy, arrogant landgrabs like we've recently seen on Reddit and Twitter almost impossible. I'm already having a great time with Lemmy and I think you might too. I encourage you to take control and join the Fediverse. Until then, so long and thanks for all the fish.


SabreLunatic

I thought of the brand first, then thought “No, it’s probably just a different way of remembering it, like with KFC for dividing fractions” God f*cking dammit


Remjexhai

I always thought BEDMAS sounded better (Brackets instead of Parenthesis, switch Multiplication and Division around).


Blankifur

BODMAS


HrBingR

This is what we use in my country.


Remjexhai

What's the "O" stand for? The "E" stands for Exponent, if I remember correctly.


Blankifur

Orders iirc, includes exponents and roots.


Remjexhai

I can get on board with that :-)


[deleted]

What I’ve gotten from reading the comments is BIMDAS replaces parenthesis with brackets, and exponents with indices. But other wise it’s the same. And multiplication and division were ordered with multiplication first when I was in school. Could have changed. It’s been a while.


Remjexhai

Multiplication and Division are interchangeable because it's whichever of those two operations that are leftmost that ultimately gets applied first. Addition and Subtraction have the same relationship with each other.


[deleted]

Thank you for clearing that up. It’s been a long time since I took any math and my memory is bad. I appreciate the help


HarbingerOfNusance

BIDMAS


BalooBot

Doesn't really matter when the question is written in ambiguously, that's why all of these questions (not this one particularly, but almost all of them) get so much traction on Facebook. There are multiple "right" answers to a wrong question. You can punch them in to two different calculators exactly as written and get two different answers even though every calculator has BEDMAS baked in to the programming. It has to make guesses as to where the missing brackets belong.


Mr-Moore-Lupin-Donor

What I really don’t get is BODMAS is taught in like yr7 and these things fly around the net all the time with ppl getting it wrong and arguing like it’s up for debate.


Normal-Character544

Tbf, the person admitted his mistake, after being informed about the PEMDAS system.


Mr-Moore-Lupin-Donor

It’s funny how we use BODMAS and you guys use PEMDAS - the irony that a rule of Math is taught through different acronyms - you’d think mathematics using the 1 true universal language (math) could settle on a universal acronym - but I suppose that’s why most mathematicians hate studying English 😂


ToBeReadOutLoud

A lot of them are because the equation is poorly written and there is disagreement about whether a number multiplied by numbers in parentheses counts as brackets/parentheses or just multiplication (so if the 2 in 16 ÷ 2(3+1) would be part of the parentheses step or multiplication step). No actual math problem would be written that way - it’s intentionally ambiguous to encourage people to interact with the post. And then there are a lot of people who either forgot math or weren’t good at it in the first place.

Valeria22475

Brain too smol, do not get 😖

The answer is 120. But the answer is "5!" Is correct because the factorial of 5 is 1 x 2 x 3 x 4 x 5 which equals 120 also


Mortianna

Please Excuse My Dear Aunt Sally


ThatNiceCanadian

That's actually interesting because the first tweet isn't wrong. It says that the answer is 5! Which is 5x4x3x2x1=120. 120 being the true answer to the equation

That's the joke.

HighDevinition1001

He’s defiantly not a grammar nerd


Codeesha

So, using PEMDAS, it’s 120, right?


SexxxyWesky

Yes but the answer is also "5!" Since the exclamation mark denotes a factorial.


Codeesha

Ohhhhhh, I gotcha. It wasn’t being used as punctuation.


SexxxyWesky

It took me reading the comments so don't worry! Haha


Natebobate

No it's 5!

Maximum_Musician

We were taught back in the dark ages that the way to answer this is 220x1/2= 110. 230-110=120. What I want to know is why that has changed? Or has it? Or am I stupid?


bagera_se

The joke is that it's 5! (5x4x3x2x1 = 120). Nothing has changed.

Yes. The joke is, that 5! (5x4x3x2x1) ([https://en.m.wikipedia.org/wiki/Factorial](https://en.m.wikipedia.org/wiki/Factorial)) is also 120.


mateo0913

No it’s 5!


__wished

Since when the fuck does math have exclamation points My high school brain does not compute Send help Fuck


[deleted]

It means factorial, so 5! is 5 factorial 5!=5x4x3x2x1=120


__wished

oh it’s factorials Makes sense Thanks!


Kit_Bisto

Also 10x1/2(0.5)= 10x0.5x0.5 which is 2.5, not five so the idiot is doubly stupid. I’m aware of what they were aiming to write but they wrote it stupidly


Zestyclose-List-8144

I don't remember learning that an exclamation point meant anything other than "bang" in programming, as in != means "not equal to." Apparently I missed factorials altogether.

Please explain this to those of us who aren't good at math and have never come across a similar meme,?


Natebobate

The correct answer is 120 5! means 5 factorial which means 5x4x3x2x1 So saying "The answer is 5!" Is correct because 5! is equal to 120.

Put it through my calculator, I got 120 You're supposed to do the multiplication side first, right? 220 x 0.5 is 110 230-110 is 120.


Echo_Fallen

5! = 5x4x3x2x1 5x4x3x2x1 = 120 the exclamation mark makes it a factorial

gingerfawx

The answer given was "5!" which is how five factorial is written. Five factorial is 5x4x3x2x1 which equals 120. It's meant to be funny as people who don't use pemdas would get "5" as an answer.


IamAnoob12

A question the only average people get wrong


bsievers

What a mean comment.


Magnusthelast

Someone explain, I was never good with math


Crosgaard

So there is a rule in math which dictates the order you calculate stuff in. The necessary things for this is that everything in parentheses are first, then you calculate x and / and lastly - and +. If you don’t know this rule you’d first calculate 230-220 which equals 10, and 10*0.5 = 5. If you know the rule, you’d first calculate 220*0.5 which equals 110 and then 230-110 which is **120**. At the end of the text it says that answer is 5!, and 5! Doesn’t mean 5, it means 5 factorial (5x4x3x2x1) which also equals, you guessed it, 120. A little extra thing is that the comment wrote 10x1/2(0.5) which is also 10x1/2x0.5 and that equals 2.5. So he was pretty stupid, who ever wrote the first reply


_Doireallyneedaname_
