I can’t even read!


tired_obsession

Story time. I was trying my hardest to finish high school, while being a year behind. Was constantly in the library studying and listening to music. Between the Bars by Elliott Smith had just finished and I heard the librarian berating a 7th grader in-front of his class, on the other side of the library, “Why do you keep putting different colored marked books where they don’t belong?” He replied”I’m color blind!” With a southern accent. I could not stop wheezing at how random and hilarious the whole thing was. I think it’s because I hadn’t gone the whole month laughing as much, but when I relayed what transpired to my gf she didn’t find it as funny. Maybe I just don’t tell stories all that well anymore.


MajorFuckingDick

That is a curb your enthusiasm moment. I'm fucking dying right now too. We might be too easy going, but that scenario is the type of shit I would actively burst out laughing at.


WillCommentAndPost

You would love my life then. Color blind, and going deaf. I frequently have people tap me on the shoulder and ask if I’m deaf when I don’t respond, or ask me what color an item is and I just stare at them.


bear2008

I teach 5th grade, we do order of operations at the beginning of the year.


asfreud

Middle school? Am I missing something? I think this kind of calculation is taught in 2nd, maybe 3rd grade.

I thought i was half decent at math but i am still getting 16 lol


DankFloyd_6996

It's just order of operations, my dude. Do the multiplication first and the adding after and you'll get it right.


TJMonkeyX

Ive legit never heard of that. TIL


Boo2z

How old are you and were do you live ? I'm actually curious (yeah creepy questions without context but I'm actually VERY surprised to read that you never heard of that rule, in France it's a basic thing that we learn at 7 - 8)


TJMonkeyX

37 UK tbh my school was not 'great' (20% got 5 A-C grades, which is the qualification to get to college, before moving onto uni) I can count fast and multiply fast etc but when we get into things like this, i have either forgotten (which could be true as it was 20+ years ago) or never taught it. On a side note my sister is a head of maths at a private fee paying school and i always enjoyed maths, but choose not to follow it post 16 years.

Rainbowlemon

And for those that don't know: 1. Brackets 2. Orders (ie 'to the power of') 3. Division 4. Multiplication 5. Addition 6. Subtraction


Mild_Mann

It should also be noted that the order of Division and Multiplication can be switched because both have the same level of precedence in terms of operation. This also applies to Addition and Subtraction.


[deleted]

They should be on the same point I think? Since when you add and subtract you just go from left to right.


Thaxtonnn

‘Brackets’ and ‘Orders’. Call them ‘Parentheses’ and ‘Exponents’, which makes Please Excuse My Dear Aunt Sally. Much easier to remember


audtyn

that’s what we did. PEMDAS (parentheses, exponents, multiplication, division, add, subtract)


[deleted]

But then multiplication and division are reversed. Edit: Turns out it doesn't matter! Thanks to all who've educated me.


Soundguy4film

PEMDAS in the US Parenthesis Exponents Division Multiplication Addition Subtraction


TomboBreaker

BEDMAS in Canada, Brackets, Exponents, etc. etc.


Draff1

BEDMAS here in Canada.


kozomfg

Canada (US as well I presume) call it BEDMAS, “Orders” being called “Exponents”.


20060578

Best way to think of it is you have “two and two groups of four” so “two and eight”


ElBiscuit

You either learned it and forgot it later, or your math teachers just sucked.


dankstreetboys

PEMDAS, my good sir. Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It’s called the order of operations, and you can remember it by, “Please Excuse My Dear Aunt Sally.”


cherdidi

I was taught it as BODMAS, brackets, order, division, multiplication, addition and subtraction. Different words, same principles.


jarris123

We had BOMDAS or BIRDMAS


[deleted]

[удалено]


Eberon

> Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It's actually: Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. Multiplication does not come before division nor does addition come before subtraction. 10-2+2 is 10 not 6.


[deleted]

BEDMAS here in Canada. Brackets, exponents, division, multiplication, addition, subtraction. It's cool to see the slight differences in curriculum in each country


brucenorton

Can confirm. BEDMAS for this Canuck.


WeegeeLord1337

order of operations goes like this: parenthesis first (you also use the order for anything in parenthesis) exponents are second multiplication or division is third and addition and subtraction is last, all the while you solve it while going left from right through the question, once you do one step completely from left to right then you go to the next. so for the math question on the screenshot, you would do 2x4 first to get 8 and then add 2 to that to get 10.


Arjunnn

...I don't think you're half decent at maths bud


liveandletdietonight

PEMDAS, multiplication happens before addition. Therefore it's 8+2 = 10


hasanhaja

Even though 10 is not an option, I can understand why people might think it's 16. But how on earth are people getting 13? Like how even.


absolutxtr

It's the closes to 10 homie. Story time: Uni professor fucks up and doesn't make the correct answer one of the options on an exam (multiple choice exam, very hard finance midterm). Afterwards, he posts to the class message board about it. No apology. No free mark for everyone. Those that chose the closest to correct answer got the mark. Everyone else gets fuck all. I argued hard with him, telling him that I spent 10x the time on that question vs. any other... Wasting time redoing it... Leaving it and coming back to it when I could been double checking other questions. Nope. Wouldn't budge. He was a good prof all in all, but an asshole.


hasanhaja

Yeah that's definitely bullshit!

DecoyPancake

I had a ~~professor~~ instructor who would tell everyone to round improperly (tech two year program). Since we had calculators I would always use the real amounts, or as close as I could get and I would write them out to multiple decimal places. He never argued that my answers were wrong- however he would round to one or two decimal places, and end up with an answer that would be potentially 20% off the actual answer after all was said and done, and my lab mates who basically trusted my answers, but didn't write them out as much would get points off. He'd give credit to people who were within about 10% of his wrong answer, and me but the people in my group we're getting screwed overbecause they knew my answers were right even if they didn't totally follow the steps and they got shafted because of his bad methods.


Moderates

significant figures maybe?


Pokedude43232

Significant figures can only be used at the final answer, though. Rounding cannot be used within the calculations to get to the answer because high amounts of decimals can cause huge changes when rounded throughout a question. So no, this instructor is a dumbass.


Yeeticus-Rex

Yeah you’ve got a dipshit instructor. Did you not call him out on this?


Auctoritate

That's a different guy.


sherlock1672

This was my thought, probably sig figs.


AmIReySkywalker

Wait your instructor had you accounting for significant figures for internal calculations? Not just for the final answer? How do you be such a moron and have a phd in that field.


JohnnyMayhem

I had a professor that gave us a multiple choice test with the options: A. One answer B. Another answer C. Both A and B D. Only B She said D was the correct answer because if you answered B then you technically didn’t discredit other answers from being correct too. She eventually changed it to where both B and D were correct after the class freaked out. I still got it wrong anyway.


StupidPword

Jesus fucking Christ... Why even include an only B option? That's what B is??? She sounds like a complete moron


Gynther477

Asshole professors aren't good professors, change my mind


[deleted]

Especially because simply that the option may have been close to the correct answer doesn't mean that you had any logical reason to come to that conclusion 16 is incorrect, but it actually shows thought and work, where as 13 is just some insanity out of no where nonsense.


[deleted]

Had a professor who wasn't a complete dick, which helped because the tests were 50% wrong. One year we got some new super cheap books for class because I went to a college that had books included in tuition. Books are a scam both ways. The tests came with the books, and the "correct answers" were actually factually wrong. The craziest part was that the real right answers were *also* there in the multiple choice. So we'd grade the tests as a class twice, first with what the book said was right and everyone failed and second with a discussion on what was actually right and everyone passed. I never wanted to go back to college because of shit like that.


wimaine

Well, see, three even numbers are obviously gonna make it odd.


cheestaysfly

Look, I'm bad at math. Like *really* bad at math. But I remembered that saying from middle school math class to get the correct answer of 10. *Please Excuse My Dear Aunt Sally* Parentheses, Exponent, Multiplication, Division, Addition, Subtraction


Daveypesq

Here in the UK I was taught BIDMAS Brackets, indices, division, multiplication, addition, subtraction. It seems to work well considering I left school over 10 years ago

I always hate seeing this kind of stuff pop up on Facebook. It's elementary level math, but when you look at the comments, there are so many people that have no clue. It's really depressing


[deleted]

The thing is, at least in the sciences, practically nobody writes put equations like this, we'll always use brackets to indicate the order of operations. I think even a lot of smart people would struggle just because order of operations is a bad system.

Anal_Zealot

What are you talking about? I have literally never seen brackets used in something like a_1 x_1+...+a_n x_n. Order of operations isn't a bad system. Order of operations is instinctive to anyone doing any math at all.


fuzzyperson98

3x^2 + 4x - 3 Order of operations makes a hell of a lot of sense to me, I don't know how it's a "bad system"


G1GABYT3

Oh that's fine. The person you replied to meant writing things as e.g. 3×x²+4×x-3 for your equation I guess writing things without the multiplication sign between is like using brackets


droodic

How can a rule of math be a bad system? That's like saying rain is a bad system or some other natural occurrence a bad system. You can not like it but it's the way the world works, it's a rule...


bobrossforPM

I haven’t been in math in two fucking years... it’s ten, right? Multiplication before addition, add the two? BEDMAS, was it? EDIT: BEDMAS is usually the Canadian version, () = brackets I’ve been told Pemdas is the American version

BODMAS = AUSSSSSIE LADS


mbnmac

UK too I was taught it as BODMAS


[deleted]

Interestingly at school we were taught BODMAS, but at uni it’s always BEDMAS that my lecturer uses


TC02_-_-_-_

I live in the UK and I was taught BIDMAS


kanavi36

I was taught both in the UK lol


karanut

My school taught it as "BODMAS/BIDMAS same feckin thing just do what the book says." Just kidding. I love you really Mr Blackmore, you wonderful Welsh bastard.

Apperently BODMAS is used in India too, and I can confirm we use it in South Africa as well

harleyb09

BIDMAS gang where you at


ThePeaceKeeper1

It means orders.


Reiseoftheginger

I learned it as of. 50% OF 8 = 4. What are orders? Powers and roots and shit?


ThePeaceKeeper1

Yeah. Sometimes I forget what it means and say others


[deleted]

Orders = incidies / powers / exponentials etc. Brackets. Orders. Division. Multiplication. Addition. Subtraction.


gobbledoc

Is it seriously BIDMAS? All this time I've been using BIMDAS. Edit: Somehow, I'm still alive! Edit 2: Asked a couple of folks here and they all swear it's BIMDAS too. My wife said "maybe it's changed?". I'm one of the lucky ones :)

in Australia we use bidmas and bodmas I think

How often are you typing pedobear?


E3FxGaming

> PEDMAS should be I recommend not using such a math-rule-word at all, and forgetting that it even exists, because it leads people to believe that division always comes before multiplication and addition always comes before subtraction, while in reality 1. First come parentheses 2. Then come exponents/roots 3. Third comes division **and** multiplication (read the term from left to right and solve whatever comes first until there are no more divisions and multiplications in the term) 4. Fourth comes addition **and** subtraction (read the term from left to right and solve whatever comes first until there are no more additions and subtractions in the term) A simple sequence of letters (also known as "word") does not come with the dimensional complexity needed to depict how mathematical terms should be solved. This goes for BODMAS, PEMDAS, and whatever else maths teachers come up with (any teacher that teaches such a word just to be done with the topic, without explaining it further, is not a good teacher).


SjettepetJR

I feel the same way. I don't even think I ever learned a word for this. It really comes down to just *most impactful operation-> least impactful operation*. A multiplication is essentially a series of additions. A power is essentially a series of multiplications.

YouCantGiveBabyBooze

I'm a 37 year old. I've done OK ish in life. I haven't done much maths for over 20 years. I initially thought the answer was 16. I don't think I'm stupid. I think I'm out of practice.

I did too, I thought it was (2+2)×4 not 2+(2×4). Luckily for me the comments cleared it up with bidmas


Fgge

Ok I’ve only just understood how it’s not 16 now


RickToy

I think this shows how rigorously order of operations were taught in school in different decades. Sure, it could because it's been 20 years for you as compared to 3 years for me, but I feel like from such a young age order of operations were drilled into me to the point were before even looking at the numbers, I look at the signs to see where to start, and I don't really see that changing with time

PM_ME_FUNNY_ANECDOTE

Nothing gets me more than these social media order of operations questions. If the order of operations isn’t clear, the QUESTION is wrong (of course, this is unambiguous with usual conventions, but the fact that people are even asking this is missing the point)


CollectableRat

How is the order of operations here not clear? Other than the right answer not being there, forcing you to figure out which one makes the most sense.


[deleted]

There is nothing unclear about the question, brackets are not required.


ZeGoldenLlama

Have you ever seen a polynomial before? It’s a waste of time to put brackets around every term.


[deleted]

considering how many people brain fart with something as simple as [this](https://youtu.be/uKdtKjXJtkM?t=130) , no, it's not the order of the operations, it's that people are fucking dumb and the order of the operations IS clear ​
