What happens when the power isn't a whole number? (Fractional Indices)

[eemeli]

I wish my math teacher was this enthusiastic

[riddhimandoley]

You know he means business when keeps his calculator in a case.

This guy is such a great teacher, you can see how he engages with the class to be a guide and helper in a journey of discovery. Not some remote pedagogue, he gets alongside them. He loves his subject, and wants us to love it too. Exceptional.

Eddie: what should i multiply this by?
Student: 7
Eddie: how bout no
Another Student: 5
Eddie: YES!

I really want to know what age group he is teaching

[guybar]

He makes these lessons so interesting that although I know the stuff he teaches I still watch it for entertainment...

[Alkalite]

Why do kids think addition when we talk about exponents???
"What number, when multiplied by itself, gives you 100?"
"50" 🤦‍♂️
"Multiply. Multiply. Multiply!"

Most people learn this stuff in the early years of HS, but I like Eddie because he explains the origins and concepts of everything he teaches. Like, he tells us *why* things are the way they are, which is the main way I remember things so it's super helpful (I find it harder to cram stuff).

I really was surprised, that they got 4*4 correct on the first try

[bieltann]

Every math teacher ever: "Let's just use whatever number I think of... Could be anything... Anything at all." *inserts very specific number to illustrate the lesson*

Why are all the best teachers in YouTube and not in actual classrooms?

[Moolhood]

The fact that I understand all of this with almost no effort even after my grades in maths 15 years ago were rubbish is absolutely astounding

[kathytarkovsky]

“Is the 3 there because there’s three fives” that killed me

[briantravelman]

This is actually starting to come back to me. I also remember learning a version where the square roots were two different fractions, and I think it's also possible for the square root to be fraction. I was hoping he'd get into those more complex aspects.

[KareemMohamed-fftt]

I couldn't concentrate knowing that he forgot ^10 on the 7^(1/10)

[catalinas.salazar]

wow, I really needed a refresh. I haven't had any math class since the start of learning virtually and totally forgot how fractional exponents worked. I appreciate it :) thanks

[tmann]

8:40 the way that you multiplied that i had to rewatch a couple of times and that’s a big brain move! Ty!!!!

6:47 "true because we said so" was how I was though at high-school. This is the first time I seen it explained so intuitively so I'll never have to remember where does what go in m/n over X. Once you understand something you don't have to rely on memory because you'll always be able to fall back on logic. The more logic you accumulate the easier is gets.

Got one anecdote from when I was around 8 years old and we learned about division with leftover. They never explained what "leftover" part was: the stuff left in your hand or the stuff you are missing to hand out so everyone is satisfied. For example 33/7 is 4(+5) but for me it was 5(+2). I need two more so there's no leftover to hand out. Lol I got the lowest grade on the test in class but it was the most valuable grade I got in my life. Because from then on I learned the importance of understanding rather than memorizing. Since then I was top guy in math class throughout my education and loved math most of the time. It's all about the teacher.

Until, many many years later, I learned from Numberphile that 1+2+3+... = -1/12. Yeah, fek math after that :)

I really hope his students appreciate how lucky they are

[esaedromicroflora]

if only my teachers had 1% of this guy ability and pleasure to teach
