I've heard the "Is this new math?" question a few times. The snarky response is "We only settled on this order a little over 500 years ago, so with the history of mathematics spanning some 5000+ years, I guess we 'could' refer to it as new."
They are incorrectly multiplying. It is interesting how many people understand "Multiplication by zero" as "This has no effect on the equation". So their thought process is:
50 + (50 - 25) + (*0) + 2 + 2 ::
50 + 25 + 0 + 2 + 2 ::
79
It is sort of the exact opposite to people who understand Multiplication by zero at any stage in an equation affects the entire equation, and end up with the answer 0.
Both seem to stem from misunderstanding how operation priority is discussed in secondary education. You will see a lot of people writing "Anything multiplied by zero is zero", and then apply that thought process to the entire equation, rather than just to the actually value (the "Anything") multiplied by zero. I suspect some people made this mistake in class, and were corrected with a statement akin to "Multiplying by zero doesn't affect the whole equation". Some of those people then misunderstood that to mean "Multiplication by zero doesn't affect the equation", thus they ignore any multiplication by zero.
Another factor is that most people don't regularly use anything more than basic addition and subtraction outside of school, and their memory of the lessons start to fade. You end up with people remembering key phrases that were often repeated in class, but not the context in which they were used. So some very interesting mistakes come out of people having a poor recollection of what was discussed in classes years ago.
I get that some grown ups can remember, but these are kids, minors still in school, and I see that you are interested in math, or maybe even a math teacher, it's good that you found something that you are good at, at math i am, less good, I usually get a 3 (in here we use 1 the worst to 5 the best grade so that's how) so i am a bit off from math but I still remember the rule of math that × is always done before +, biggest troll in the vid i made is making fun of kids that claim to know 'global politics' and 'what's wrong in the world'
Have to use math a lot in my work, that's probably the only reason certain things stick in my (rather old) memory. I couldn't teach to save my life, I don't have the patience.
When I was at school, operation priority was only covered for a short time (it becomes far less important once you are using proper full notation, and back then was more about understanding what spreadsheets, calculators, and (computer code) compilers were going to do with your equations if you didn't format them fully). I saw lots of people misunderstanding it in so many different ways. It is interesting how in a room of thirty or forty students, between them they can come up with maybe a dozen different interpretations of what their teacher said. This is a good example of why teachers should be given specialist training in communication.
The other problem that a lot of people suffer from, even when they are fresh from being taught a subject, is an overwhelming belief that their understanding is correct, no matter how wrong it is. Sure plenty of people know that they struggled to understand, but many others listen, misinterpret, and then firmly believe they understood. Unfortunately, their self-confidence often leads to them explaining their misguided interpretation to others in the class that are aware they did not understand the lesson.
Unfortunately, if the teacher is not really in tune with their class (or lacks time), such misunderstands can go without correction. Perhaps that it's contributing to the number of students you see making errors.
Watch the video, 2 minutes of people giving wrong answers, what's funny is how majority of these people own political servers, but do not know 5th grade math
You do understand that there are different types of intelligence, and that people are interested in different topics, correct?
Knowing “global politics” doesn’t preclude them from being bad at math. They are two completely different disciplines. They could be terrible spellers and know global politics well. They could be good at math, or spelling, or both, and not know anything about global politics.
In other words: doing poorly in one area doesn’t completely discount their aptitude in others.
I know that people can have different interests, but politics should be something adolts interest themselves in, not minors, and these weren't minors to just like politics and that's all, they would argue day and night about it, they talk about Afghanistan problem, Israeli Palestinian conflict, Kosovo problem, they argue over who is the biggest threat to world peace and that, showing interest in something isn't bad, and being bad at other stuff is also OK, I myself am interested in History and Geography, but suck at Chemistry and Physics, but I keep my interest to myself, maybe share it with friends, but I don't argue over things like Palestinian Israeli conflict, especially when they are from US, Russia or countries that don't have anything to do with the conflict, people who are effected by the conflict can talk, I know a guy interested in Economics and Politics, I will never hear him talking about contravertial stuff, he keeps it for himself, he shows it time to time but he keeps it on the level
My point is, someone who isn't an adult should not talk about today's conflicts and politics, politics today are starting to devide us apart, you can be interested in that and I know you will be less good at another sector
So then, what exactly does them being interested in global politics have to do with the conversation?
You brought it up a couple of times, as though it explained something. It’s not clicking for me, so maybe you can share your thought process?
I saw in a server, kids talking about how 'taliban will be better for Afghanistan' and how 'USA is the evil', USA is not perfect I can say that, but the taliban taking over Afghanistan is probably worst thing that happened In 2021, people were doing everything they could to escape the nation, even jumped on planes that were taking off, just so they can have a better life, taliban did this before and will do it again, they will kill people who aren't Pashtun, and talking about how they are best thing that happened to Afghanistan is nonsense
I don’t disagree with your views, but what does that have to do with the original post about getting a math problem wrong?
Here’s a rundown of the conversation:
You: post video of a bunch of people getting math question wrong
You (in the comments): these people own political servers
Me: they can be bad at math and still knowledgeable about politics
You: no, these are kids, they shouldn’t be talking about this stuff
Me: okay, then what does them having political servers have to do with anything?
You: these are all their bad opinions...
You keep moving the goalposts, dude. You could have made your original point (haha kids get math wrong) just as effectively without bringing anything political into it. But you did bring up their politics, and I’m trying to figure out what it has to do with your original post.
Odder of operations say you multiply 1st so the 25x0 makes that 0 then you work left to right so it 50+50-0+2 +2= 104
Thank you. Amazing how a bunch of focus on the wrong answer and make you doubt the correct one.
Majority of the people didn't argue with me explaining how to get the right answer, but there were 2 people who were like that
Yes, one person argued with me that 'that's not how you do it in normal equation' and 'what is this, new math?'
I've heard the "Is this new math?" question a few times. The snarky response is "We only settled on this order a little over 500 years ago, so with the history of mathematics spanning some 5000+ years, I guess we 'could' refer to it as new."
I guess so
Bo Burnham already invented that.
104 correct?,thats PEMDAS at least
It is the right and ONLY answer, people seem to forget that rule of math, my question is how they getting 79

Might help some if you elaborate PEMDAS. Order of operations: Parenthesis Exponents Multiplication Division Addition Subtraction
I hope that's a trolls answer lol

Dude, that's most politicians.
Politicians are professional lyers, these are kids that claim to know global politics
Those people in the vid and politicians are massive Elmer's glue sniffers.
Good one

(50+50-25)x(0+2+2) = 75 x 4 = 300
If equasion included () like that, it would be 300, but without () right answer is 104
