For future internet historians: At 1:22 Mr. Woo mentions "People who have spent time on their phones recently know these numbers very well". This is because in 2014 a mobile game called "2048" was all the rage. In that game you slide numbered tiles around to combine like numbered tiles to create larger numbered tiles. The lowest number is 2, so as you can imagine the combinations follow a 2n pattern. Hence 2, 4, 8, 16, etc is quite familiar to young students at the time.

Exactly

My favorite argument for why 0! = 1 is the Combinatorical argument for it. In Combinatorics, n! is the same as the number of unique ways you can rearrange n items into n unique slots, because you would have n choices for where to place the 1st item, n-1 choices to place the next item, and so forth, you multiply all of your choices to get n!. So 0! should therefore be the number of ways to rearrange 0 objects in 0 slots, which would be 1 because there's only 1 way to do it and you cannot change it.

Since I see so many other people telling personal stories, I'll add mine to the pot. Eddie reminds me of my current AP Calculus teacher, whom also taught my Precalculus class last year. Now, up until Precalculus, I didn't really care too much about math. I was always pretty good at math, but it wasn't something I really thought much of. It was just another subject in school to me. This mindset changed when I took his class. This Precalculus class (which I took at the same time as my school's Algebra 2 class) scratched an itch that I didn't know I had in my brain. Not only were we learning things as well as why and how they work (which was a first for me), but my teacher also knew where the concepts we were learning got applied. Whenever I'd ask him where the subject we were learning was used, he would say something like "Oh, this stuff is used to calculate the shape of Formula 1 cars". In just that one year, I went from being indifferent to math to actually liking it quite a bit. Fast forward to now and I am completely in love with math. Although calc can be hard, there's just something about that is so... satisfying. And my teacher has kept his trend of giving examples of where things are applied whenever asked. This comment is to you, Mr. Kramer. Thank you so very much for igniting a passion that I didn't know I had

For last 50 years, I'm one of those who accepted 0! is 1 *but* I now know how! I should try few other various based on those patterns. Nice one Mr.Woo. Thank you!

I do appreciate the exponent view going backwards, which was one of the ways I introduced extended exponents in my class. Doing that for factorials was something I haven't seen explicitly spelled out before. Also great was the teachers clear love for the meaning and consistency properties of math - the "it just works". This was a very nice presentation. I do wish the more general point was also presented - that empty products are always 1, just like empty sums are always 0 - and the why for that given, but obviously I have no idea what else he presented to his students after this 6 minute fragment. I just like to show kids how you can break products like Pi(0

that was a fun riddle, well presented, it is all about patterns. working with programming consistency and patterns are things you will encounter all the time, but also in other forms than maths

That's how our Maths teacher used to ask questions during middle school. Things we studied, but never thought how worked. He asked Why is 2⁰ = 1 and not 0, What did 0⁰ value? etc. We loved him, he teaches us Physics now but his Maths classes were the best.

I find it wholesome that he lets his students breathe, like how a comedian stops talking while the audience is laughing. Some teachers hate those micro feedbacks, such as laughing and murmuring discussions. Nevertheless, both show respect as the students get silent when the teacher starts talking.

For exponents of like bases you simply subtract values when dividing. so a^10/a^3 = a^7, but a^10/a^10 = 1 for obvious reasons. Therefore, a^(10-10) = a^0 must also equal 1.

As an educator for the past 20 years, yes, there is a sort of satisfaction with getting this sort of reaction from a class. It demonstrates engagement; But what's infinitely more satisfying is (assuming you have their complete attention and all in the same page) when you get them to truly contemplate a completely new or groundbreaking idea; something that challenges their existing notions and understanding. Even better, If you get them to start asking additional questions to process that idea, and they start asking those questions not just to you as the teacher or facilitator, but to each other in class, and then it ricochets back and forth between you and the rest of the class, those are truly the moments that make teaching satisfying, IMHO.

I once had a substitute historian teacher, for like 3 months, and she would talk about the time period like she was a time traveler, explaining how the society worked back then, politics, religion, etc. It was the best. So after that i realized there's no bad disciplines, only bad teachers. The reason for the latter varies, as we all know...

It’s not always up to the teachers though, you have to remember they are part of a much larger system. There are certain standards and checkpoints that have to be met in order to satisfy the state or district. This results in the bullet point learning you hate. Your substitute isn’t beholden to this because they’re just a placeholder, so they have more freedom to teach. It’s a sad state of affairs but one more complicated than teachers being shit.

Mathematics, as a discipline, is one of the various conceptual worlds. It resides in the minds of people. Language enables sharing and discussing mathematics, so it becomes ever refined. But the primary source of mathematical ideas is the physical universe, for its natural laws are constrained by mathematics, not the discipline but the underlying pattern or subset of the whole of idealized relationships, known or unknown. An example of a primary source of mathematics: Natural numbers relate to collections of individual objects, they are the collections' cardinals. An example of a non-physical application of mathematics: five mathematical theorems, three dreams, eight contradictions, four myths. Engineers constantly deal with the physical world, it's their job. For them, the relationships between mathematics and its primary source, the real world, is fundamental. Mathematicians constantly deal with the discipline of mathematics, of course. They try to squeeze the most of what they best know, and so, mathematics expands. Philosophers also appreciate mathematics. Bertrand Russell's paradox of "the sets that do not contain themselves...." is an example. Artists and mathematics? Of course! Tilings are an example. Fractals, another. So, who do not love mathematics? Those who heard that mathematics was something hard, ugly and unworthy of trying. Those who prefer sports to thinking. And so on.... My daughter is 35. I have been teaching her mathematics for a whole year, for she asked me to. She was not too comfortable with what she had been taught at school two decades earlier. She takes free time for mathematics whenever she can, even though she has to work hard most of the day for a living. I am very proud of her.

For those who are hungry for more maths, I am a college student and I don't blame HS teachers not showing the real reason why 0! = 1 because the real proof involves an indefinite integral called "gamma function", which you solve by integration by parts, and this function defines factorial for any number, even 0, even negative numbers and fractions, when you try to calculate the factorial of 0 by gamma function, the result is one, I really recommend reading about the gamma function and stuff because it is really interesting, and just a little teaser, the factorial of 1/2 is the square root of pi divided by 2 :)

Despite that, there are also many kids that prefer to just zone out, not take notes, not attempt any work, prefer to try get on their phones, or try to just do anything other than math. All these kids say it's super hard... Anyway, my point is no matter how great the math teacher is, there are always students that will ignore instruction.

As a professor, I long to teach a class that is as engaged as the class in this video. Side note. The two examples given at the end of the video, Fourier analysis and complex numbers, were not developed just because they were cool (no disagreement they are indeed cool, btw). Fourier developed his theory to solve certain differential equations (namely the heat equation), and complex numbers arose out of trying to solve the general cubic polynomial. Yes, these areas are cool, but most of the time, there is some concrete interesting problem one is trying to solve when developing some new mathematical method.
