- I learned this delightful trick from this @numberphile video featuring the brilliant James Grime (@singingbanana): • James ❤️ A Card Trick ...
This video was originally broadcast for EducationLIVE, part of the NSW Department of Education's resources for assisting children and parents learning from home during lockdown: fb.watch/v/TxdiLvFj/

Switched red marker and blue marker 10 time and put cap on everytime, only a true mathematician would do it.
You can do better :) ua-cam.com/video/-HQrpaveZJo/v-deo.html
I remember our VG sir 😀
@@raynalguillaume Of _bloody_ course someone would ping BPRP XD
And then there is BPRP
he's so enthusiastic about math, its so wholesome :)
i didnt really enjoy math before, but his ted talk inspired me, and now math is my favorite subject :)
Thank you, Mr. Woo.
His Ted talk was average... 🤣🙏 But he is a good teacher👌
I did not like math
Enthusiasm changed me
Thank you Mr. woo
I turned your comment into a haiku.
He is about math just like girls about scrotal sack
@@reststop3632 haha that was clever and creative at the same time, loved it 😁 nice inspiration you got there
@@christianpaul3651 🤣🤣🤣
Eddie makes maths worth it
thanks really appreciate it
Yeah
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!
Square not square roots

New favorite channel. 43 yr old engineer business owner. Can't wait to introduce my kids to this content. Bravo
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.
Another way to think about it:
Assume you had 10-6 as one of your pairs.
10 is the highest card; there can be no card higher. It's in player A's hand.
in order for it to line up with the 6, the 6 must be the lowest card in player B's hand. (because the highest card in player A's hand matches with the lowest card in player B's hand)
What 4 cards can be higher than the 6? 7,8,9,10.
But we already used 10; so this is an impossibility. There are not 4 cards higher than the 6 left to fill out the other player's hand.
@@EtoileLionYour explanation is correct of course. It’s an important point that is missed in the video. However it doesn’t strictly prove that if it’s true for 10, it’s also true for 9 then 8 etc. Perhaps a form of inductive reasoning is necessary.
That aside, without affecting the result, the two players could vertically swap their highs for lows so one has all highs and the other all lows. Then the H-L formulation is obvious.
BTW I’m not sure it’s possible to prove it’s true by strictly algebraic means. I suspect not.
I've never seen anyone so happy about math and about calculations making sense. Great job!!
To me it feels like he's competing with Matt Parker from Stand-up Maths on that matter. :D
I can only agree though, it's done really well.
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.
Please keep doing the excellent work you always do Eddie. Keep encouraging kids to Math. Thank you
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
Yeah, true
I love math, i love that Eddie loves math, i love Eddie for making math fun. Thanks Eddie.
Yes, beautiful patterns. Very beautiful. Thank you Mr. Woo
This improved my mood a lot. Thanks for sharing this video.
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!!!!
Like you Eddie, always smile and relaxing. Good personality.
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!
I love your videos. THANK YOU for making maths so fun for me.
The way you explain is superb... ❤️❤️❤️❤️❤️ I just loved it ❤️
I love math ever since I've discovered your love, excitement to math
Eddie, you are living legend!
Excited to watch this video!
So good!! Definitely will try this with my class. Thanks a lot, stay safe
New to the channel mad respect for the work you are doing here.!
I love this kind of videos !
Eddie is a mathemagician!
Beautiful and fun yet so simple thank you for this video :)
Eddie woo is good at everything
I love this guy!
Really admire your knowledge in Mathematics, and the way you teach, thank you for informative video you just made Mathematics fun to learn. You are like my favorite Prof Roger Antonsen. May God bless you Prof Eddie Woo☺️
And thank you so much for this video.
It’s always nice to see self working tricks in action since most of them are based on math
Sir you are one of the greatest teacher I have ever seen
Wow, it's so amazing.
Mind blowing!
Well I knew he was a magician in the classroom, I never expected him to start doing card tricks!
This was a very awesome video, he explained the logic behind this trick so well :D
You are a very good teacher
OMG!!!!! I love this. Thank you ❤❤❤❤❤
OMG!!! I NEED THIS TEACHER!! he is absolutely the BEST! :3
We need more videos like this.😘
Thanks mr.woo you're m'y light in math
you are math crazy! I love it.
Amazing!
It will be so great and meaningful to be Eddie’s student😍🔥
you make it looks so easy !
I wish that i have Eddie as a teacher when i was younger bro💕💕
I wish he would do videos on the concepts behind Fourier and Laplace transforms!
Eddie, Great presentation! I am a magician who loves mathemagic but who struggles trying to make it fun for audiences. Your style is great!
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.
3:48 Loneliness just hits different 🥲
I love you sir. You are my most favourite mathematics teacher.
Man I wish I discovered you much much earlier, still is better late than never
Before I’m a magician, now Im a mathematician. Thanks to you!
So true, same here. Now I can have them count down to 25 in the 3 deck and have that number in the envelope.
More please 🤯🤓 looks like the building blocks to those bigger prediction tricks that are all too common now
He knows that that shuffle is a wash.
This guy has wrecked home games.
Math & magic 2 things I love ❤️
Amazing
Just wow!!!
Well done!
Awesome, very interesting
Big fan...
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.
Ralph.
Wow
Very good, thank you master
Great video
i wished you have been my math teacher. Thank you
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
WOW! Incredible hidden patterns
For we the Mathematicians, we know it's possible. But you could have tell other people that you have a paper hidden which you will reveal in the end.
Great one mentor. 💪
ohnestly you're just the best
Just by hearing him explaining this you know he's a teacher. Methodical.
great sir❤❤
You should explain some magic card tricks (David Copperfield). He has some cool tricks easy to explain with mathematics
I'd like to see an episode about applied math on physical training sometime :D
Cool!
Thank you sir
PERFECT
Numberphile did the same trick. Still fun to watch
The rearranging of the cards to ascending order from low to highest is the key on this one, or else this thing ain't gonna work. Still a great vid Eddie 🍻
Respect
he is very smart
Here before this blows up!
He looks like he uses 5 chopsticks to eat instead of a pair.
Hey! We need some brown paper! In the spirit of Numberphile, of course.
A great presentation. I’m sure students would enjoy learning maths with Eddie - he’s really enthusiastic and explains things so clearly. I’m a scientist, so need to know some maths (especially statistics), but I feel it would be good for me to brush up my maths knowledge by attending his classes!
Hi Eddie, a humble idea: try to lower the Gain on your mic channel to get rid of the overdrive on it.
my favorite math card trick involves 21 cards where I can guess anyone cards no matter if it is the first, last or a middle anywhere card. by the third move, I already know their card before finishing the trick. i can then just move cards around into multiple piles and by the end, I have their card left that they had chosen. it's called either 21 Cards or Magical 13
BEATIFUL CHANNEL UA-cam MATHEMATICS... BEATIFUL..
the second time you layed out the cards you put down the exact same thing i had
I wish there was a maths degree dedicated to you sir
I like it
Fun maths
*just like tha FED from wanda vision of the same name!*
We were at Chatham High and I was from Cundletown Public
I hope and wish my comments are not offensive to anyone, but I hope God continues to illuminate Eddie woo's beautiful mathematical brain to help him find the answers to the many issues affecting our world. You are very inspirational and an example for others to follow.
Nice game
Woww ❤️❤️❤️👍🏾👍🏾👍🏾👍🏾
So the fact that your first attempt gave palindromic red in the middle was just a coincidence?
Interesting
hi can i interpret as this too ?
taking any number range (1-10) that split equally random to two group, where each group hold 5 cards, then the possible 'red' value will be 5^2=25
another example , a pool of number range ( 1-18) that split equally random to two group, where each group hold 9 cards, then the possible 'red' value will be 9^2=81
this x^y where x is number of card that hold by a group after equally divided from the pool, and y = number of group divide. this will hold true for 'red' value if and only if number of group divide is always 2.
Nice 10th Doctor cosplay :D
