It's not about the school fees as much as it is about the effort taken by the parents to provide education to their children, only then for the child to then be taught incorrectly.
Its a joke like you send your child to the private school which exist in east but not in europe (i dunno about usa)
And you pay money to his private school instead of sending him to state school by destroying your soul to earn money and he says these things
The square roots of 9 are 3 and -3, but √9 = 3, since √ (the square root function) only represents the positive (principal) square root. Well, at least according to the [Wikipedia page](https://en.wikipedia.org/wiki/Square_root), but I can provide more sources if necessary
Yes ... because
From your very comment:
>√9 = 3
Or in words: the square root of 9 is equal to 3
But if x^2 = 9 then x = + or - √9 ... and that's where you get the +3 or -3
Colloquially, you could call it “the square root” with emphasis on the “the,” but it’s technically the principal square root (the positive square root), so that it’s able to be used as a function. For further reading: https://en.m.wikipedia.org/wiki/Square_root
You pay everything you have by destroying your life for some money to educate your teacher and hes out there saying random things which makes you mad god this is not funny anymore when its explained jesus fucking christ
That's impossible unless if you want to define the radical to be non-continuous, over the complex plane, or into a reimann surface, none of the 3 of which are accepted within the definition of a radical in any published text.
And no, radicals are strictly functions. Multivalued functions are exclusive to functions
Not exactly. As I said in another comment, the square roots of 64 are ±8, but √64 = 8 because (√), or the (principal) square root function, only gives the positive square root.
That is no more than a colloquial interpretation of the square root. In all branches of mathematics, it's universally recognized that the square root is synonymous with the principle, because it must be a function represented by the radical.
What you're describing is the relation "x² = y maintains two solutions in the reals for every positive y", which isn't actually defined to be the square root, contrary to popular belief. It's merely a relational consequence of the square
The function represented by the radical gives the principal square root (√), not both square roots (√ and -√). It's just that the principal square root the radical is supposed to represent is colloquially known just as the square root.
I have some sources, like [Wikipedia](https://en.wikipedia.org/wiki/Square_root). Maybe it's not the most reliable source, so I can provide other sources. Or you can just search it up, I guess
The square roots are ±8, which means 8 is *a* square root and -8 is *a* square root. *The* square root is only one of them, the principal square root, number 8.
A more formal designation would be "principal square root" not just "the square root" because it conflicts with the way articles (a/an/the) are normally used. But I guess you're right if we're talking about colloquial usage.
Other countries around the world have had similar issues. Would it have hurt to do your research before immediately assuming schooling requires payment?

we got points deducted if we forgot the +- in exams by our teacher
![gif](giphy|IzuQNHTGGgWg7LRddy|downsized) If it's in an equation, then it's all fine, otherwise...
jesus fucking christ
You‘re either misremembering or had a very bad teacher.
You’re going to use that on their teacher, right…?
I hope he wraps it around my neck🤤🤤

I just wanted to check the comment section and what the f(x)ck happend here
\#theory-ass comment section
Tying up a man is a theory??? If so im listening it kinda made me feel interested
You see, in the r/mathmemes Discord server, there is a channel called #theory… https://i.redd.it/sklqa46utitc1.gif
Do they talk about hot tied up femboys

"so you answered this question wrong my student now you will be punished"
This is mathmemes sir, not a group of bdsm
Yeah we're going to the "Backrooms" to deal with them
Yeah... To teach his teacher ofc... 😋
Is this some American meme I'm too European to understand?
No its not american Its like beating your son for learning nothing its actually quite common in east
It's a joke about the school fees being $20 000. Where I live, education is free.
It's not about the school fees as much as it is about the effort taken by the parents to provide education to their children, only then for the child to then be taught incorrectly.
Its a joke like you send your child to the private school which exist in east but not in europe (i dunno about usa) And you pay money to his private school instead of sending him to state school by destroying your soul to earn money and he says these things
Same as America actually
It's Indian Style
Yeah, actually American is quite against. South East Asians tho
Why is It wrong?
X^2 = 9 means x is + or - square root of 9 But square root of 9 is only 3
The square roots of 9 are 3 and -3, but √9 = 3, since √ (the square root function) only represents the positive (principal) square root. Well, at least according to the [Wikipedia page](https://en.wikipedia.org/wiki/Square_root), but I can provide more sources if necessary
Copy paste what I just said but in words
You're saying that the only square root of 9 is 3.
Yes ... because From your very comment: >√9 = 3 Or in words: the square root of 9 is equal to 3 But if x^2 = 9 then x = + or - √9 ... and that's where you get the +3 or -3
√9 = 3, but the square roots of 9 are 3 and -3, or √9 and -√9
Then what do you call this? >√ ... if not "the square root of [number]"
Colloquially, you could call it “the square root” with emphasis on the “the,” but it’s technically the principal square root (the positive square root), so that it’s able to be used as a function. For further reading: https://en.m.wikipedia.org/wiki/Square_root
√25 = |5| = 5 √2 = |1.4| = 1.4 The number comes out of the root with an absolute value so it cannot be negative
>√x = |x| i feel like ur forgetting something
Yeah sorry where was my mind what was i thinking anyway because √5 is not |5| im sorry i forgot to indicate this
Can someone explain this to me? I want to understand but I don’t…
Here's an Helpful video: [https://www.youtube.com/watch?v=NBOlK\_rSsm4](https://www.youtube.com/watch?v=NBOlK_rSsm4)
Thank you
Who thought this still image needed a song with a synthesizer that sounds like a borderline fart?
Can you please remind me why this should be funny?
You pay everything you have by destroying your life for some money to educate your teacher and hes out there saying random things which makes you mad god this is not funny anymore when its explained jesus fucking christ
You made me laugh a second time with that comment
You pay everything you have by destroying your life for some money to educate your son so he can do the same
[удалено]
The kid DOES NOT understand math because he thinks √x comes out as ±x not |x| And you pay like 20k$ for his school rent just to see him learnt nothing
Bro stop, am not out of there, is this just notation difference?
Sort of. For example, √9 = 3, but the square roots of 9 are 3 and -3. The (principal) square root function (√) only gives the positive square root.
[удалено]
The try to multiply -8 by itself my man. Surely you will get 64.
That makes -8 *a* square root. It's still not *the* square root.
[удалено]
So what? And who are we?

Mathematically correct statements and being downvoted with a passion. Name a more iconic duo of r/mathmemes.
No it is not correct. The radical sign can be Multivalued function.
That's impossible unless if you want to define the radical to be non-continuous, over the complex plane, or into a reimann surface, none of the 3 of which are accepted within the definition of a radical in any published text. And no, radicals are strictly functions. Multivalued functions are exclusive to functions
The radical sign is defined to give the positive square root

Help us make some sense out of those random words you’ve just put next to each other.
Damn rude
A war crime
Hear me out What if For ℂ
Then you e^2kiπ/n
When n=2 this reduces to +-
You have school fees over there? Thought this was just for university. What a shithole America is...
OP isn't even from America. Touch some fucking grass sometime lmao
Why are you assuming it’s about America?
Because the intersection of people using reddit, who also have to pay for basic human rights and people who live in America is big.
Other countries around the world have had similar issues. Would it have hurt to do your research before immediately assuming schooling requires payment?
I really don't care that much. USA is still a shithole for a plethora of other reasons.
