Hey, thank you so much for this. At this time of writing the world is deep in coronavirus, and I'm figuring how out to make math lessons more engaging for my students in the future. Your enthusiasm is palpable - I am looking forward to getting back in the classroom!

[@exportation]

The fact that you know something does not automatically entail you can teach the subject to people, and this is the biggest problem in many schools. The only way to teach something is to generate interest in the listener. Eddie has done more in a 10 minutes video that my math teacher in 5 friggin' years.

I wonder if you could derive pythagoras from first principles in abstract math. I'd like to compare it to mine which also proves Fermat's Last Theorem.

To me, the most fascinating aspect is how the geometry can be represented in an equation, and how these proofs can be used to aid the construction of objects, even in ancient times, whether architecture, clothing, transportation, or whatever application was at the frontier of innovation. Even now, geometry knowledge is gold, for many careers or hobbies.

[@neoweechang8256]

I am sad that u r not my secondary school teacher. If u r, I will have learnt the fun of math instead of just memorising what I have been told to. Learning math should be like this, understand and apply. Too sad to say that Malaysian education has fallen behind too much, hope to see improvement in our level of teaching. Good job, Sir.

[@neoweechang8256]

I have been good in math, but I never realise learning math can be so fun. Yes, I did get good result in all my math exam, but basically I just memorise what I have been told to, memorise exactly what I saw in the textbook. Learning maths is more than this, understand the basic and the meaning of it is more important.

[@od5699]

Are you familiar with dimensional analysis Eddie? Why not also state that a rectangle is not the only shape that applies to this theorem. Semi-circles, circles, a regular pentagon, a regular decagon , a regular polygon can replace your square, in fact, it works with any similar shape. However, with diagrammatical proofs or with nines complement there is no indication as to why? Can you suss it out Eddie?

[@official-obama]

Simple, the area when scaled changes proportionally to the square, so the area gets multiplied by the square’s. s(a^2)+s(b^2)=s(c^2) works out to s(a^2+b^2)=s(c^2) and then we divide both sides by s to get the pythagorean theorem.

Hello Teacher Eddie, i am happy in your teaching. We use big side as 5 (Diagonal) intermitted side =4 (Opposite side) Smaller one = 3 ( adjacent side) 3(square) + 4(square) = 52(square) Sum up: 9+16 = 25 25=25 tada..... tada.....

Yeah, It's awesome how there are proofs for this theorem that make sense for right and left brained people!

Sam Anna, there are three or four different ways to prove ....and it's more convincing to kids if taught in all different methods.
