"other things that can grow arbitrarily large..."
why did my mind go places?

[jakobr_]

The way I think about the Rearrangement Theorem is that conditionally convergent series are essentially subtracting one infinity from another. So it makes sense that literally any number can result.

You won't "frustrate" (or trick) any maths teacher with those misconceptions. They went to university... to study maths...

[TrimutiusToo]

Kinda pity you, Bri... Seems like you were unlucky to get bad teachers

[cjbralph]

As a teacher, the most frustrating thing about this video is the sponsored section in the middle of the video.

The one that breaks my brain the most is the Banach-Tarski paradox. If I break a solid object into finitely many parts, then move those parts around and put them back together, I should have the same volume, right? No, we can split a sphere into five pieces and use them to reassemble two spheres the same size as the original.

Great visual with the cylinder. Perfect for HS geometry students to understand the relationship between surface area and volume.

Changing order of addition doesn't matter: infinite sums are not sums, you are not changing order of addition you are taking the limit of a different series. I also don't get the title: any teacher will surely be aware of all of the situations presented in the video.

The thing that frustrates me the most is the title 🤦🏾

[thea.igamer]

Really liked the phrase "Your knowledge can grow arbitrarily large". 😂

[martinepstein]

Good stuff. Man, I was dead certain this was going to be another -1/12 video.

6:59 Actually that's WRONG! 0.207879 is a complex number with no imaginary part.

[meiliodinson]

I always cry when I see people not including 0 into the natural numbers.

[Mebasically]

I don't really see which teacher would be frustrated by a student knowing that thes are "misconceptions" about maths....

[SC-zqcu]

Me: For once please try to be reasonable !
Math: Haha ! In your dreams fool !

[mrosskne]

Why would this frustrate your teachers? These are some of the first results you're taught in the related courses.

1:43 "That's obvious, right?"
*immediately thinks of Zeno's paradox of infinitely dividing the distance between point A and point B by 2*
Nothing is obvious when infinity's sitting at the table with mathematics 🥲.

It really did frustrate my English teacher. She couldn't understand a word.

"Just add 1 to each digit" doesn't work because you may encounter 9. "Add 1 to each digit except 9 where you subtract 1" might work, but might run afoul of 0.999...=1 related shenanigans. Use 5 if the number on the list doesn't have a 5, and use 6 otherwise. Much safer.
