Switched red marker and blue marker 10 time and put cap on everytime, only a true mathematician would do it.

Eddie makes maths worth it

New favorite channel. 43 yr old engineer business owner. Can't wait to introduce my kids to this content. Bravo

I did this with my class, then I had them take away the 9 and 10 and try it again with 8 cards, then again with 6 cards to see if they understood that they got square root answers...25, 16, 9!

19:00 it’s because of the nature of ordering the numbers from left to right: there are 5 low cards and so if there are x low cards in one pile there will be 5 - x low cards in the other pile. Since the cards are ordered from left to right a low card can never be opposite a low card and in turn a high card can never be opposite another high card.

I've never seen anyone so happy about math and about calculations making sense. Great job!!
-
I found your channel recently and I've never been taught math this way. You are beyond amazing and your enthusiasm makes it worth it.
-
I love math, i love that Eddie loves math, i love Eddie for making math fun. Thanks Eddie.

This can be generalized as well. If you have a set of the first 2n numbers broken into two random groups of n numbers and paired off in this way then the differences sum to n^2

Please keep doing the excellent work you always do Eddie. Keep encouraging kids to Math. Thank you
-
Thank you so much for this demonstration Eddie. I am a computer science lecturer and I used this 'trick' to highlight the importance of pattern recognition; one of the four key characteristics of computational thinking. My students were laser focused and engaged and loved it!
-
Like you Eddie, always smile and relaxing. Good personality.

The world really needs more teachers like you sir. Being a math enthusiast, I love watching everything you teach and explain. Its about the cheerfulness and passion for the subject and the way you teach. Math is really beautiful. We just need someone like you to show us that beauty. Hats off!!!!

More interestingly, playing cards represent the Cosmos. 4 suits = 4 seasons 13 cards per suit = 13 lunar months in year 52 cards in total = 52 weeks in year 364 total all spots = 364 days in year Plus the Joker representing the odd 1 or 1.25 …thus equalling 365.25 days in a year This is the reason cards were esoteric and mystical.

I really want this kind of teaching in my country, although I am a commerce student, but still our education needs to be interesting like sir showed today.... Literally Sir, Instead of choosing celebrities, I would choose you as my role model Regards A Proud Indian & Your Subscriber.

OMG!!! I NEED THIS TEACHER!! he is absolutely the BEST! :3
-
This improved my mood a lot. Thanks for sharing this video.

Great fun ! An other way will be to look at the 5 vertical columns. Where we have 10 the addition of the 3 cards will give 20 where is 9 will give 18 , 8-16, 7-14, 6-12

Well I knew he was a magician in the classroom, I never expected him to start doing card tricks!
