what a great guys he is. hes so passionate about numbers so that you automatically think with him through 55mins. it went so fast i cant believe i followed him all the 55 mins and i thought i got attention disorder. im going to watch other videos suggested by youtube, hes just great. hes the perfect teacher. at first he was awkward but then you just start to follow and see what a great great guy he is. he even knows what difficult is for the untrained people so he breaks it down so everyone can understand his thought process. i wonder what his opinion is on common core ...
That man is a goddamn genius!! I can never get over his final showdown calculating stunts! And yes, I call them stunts because I think that no ordinary human-being would ever be able to do this without a calculator!
For guessing the missing digit You just need to add all the digits and they must be a multiple of 9 Eg last one said 662211_ so adding the digits, we get 18 which is already a multiple of nine so the missing digit is zero...similarly, if suppose someone got 547621_ the sum of which is 25. So the nearest next multiple of 9 is 27 (9×3) and the difference of these (27-25) is 2,the missing digit
The missing digit is not always 0 if the addition adds up to a multiple of 9… you’re basically guessing a 0 or a 9, but can do it in such a way, like Mr Benjamin does… “I’m getting a lot of nothing… did you leave out a 0?” And if the person says no, you can be like “well that’s strange, cause it seems like you were thinking of nothing. Did you leave out a 9?” Either way, it looks like you got it right.
FINALLY!!!! someone´s brain that works like mine!!!!!! I had always had a hard time explaining to people how I do my calculations in my head, he does them like I do! A lot faster obviously but its the same thing!
I have been a fan of Dr. Benjamin since the early 90's, however there seems to be a misperception that being able to do all of this mental numerical manipulation will translate to excellence in a typical high school or college classroom, which isn't the case! I happen to teach math at a local community college and I love doing mental calculations as a sideline but it continues to remain separate from the material that I cover in my courses.
Was it by complete chance that all the 4 numbers picked by the audiences at 5:30 are multiples of three?? so he was able to do the trick at 9:00 ?? I don't think so !!
+Danny Smith brett is male name, traditionally, so it would only be right to assume brett has a penis. not a vagina. not that it matters really, but maybe in future just think a little first because a) boys don't have vaginas and b) suggesting he does as some kind of an insult is derogatory to women and sexism is a bad quality. so. please don't? i feel I'm being super reasonable here
@@CH3LS3A you mean shakuntala devi goddammit!She did not square a 13 digit no. but multiplied a 13 digit no. with another 13 digit no.She also has the guiness world record for it.
The age we live in where you've got to ask a child if his or her birth date is embarrassing or too personal oh the age of the manufacturing of snowflakes has hit an all-time low think about it

Math is hard if you don't love it and practicing everyday. Thanks Mr. Arthur Benjamin. You're really a math teacher.
I love his energy everytime😂
I wish he was my math teacher :(
you are most definitely not alone.
Go to Harvey Mudd College, and maybe he will be!!

He is brilliant I am a mathematician that already competed in other countries and he is even better than me.
That man is a goddamn genius!! I can never get over his final showdown calculating stunts! And yes, I call them stunts because I think that no ordinary human-being would ever be able to do this without a calculator!
+Matthias Köhler (MattK269) I can do it! I am currently squaring 7-digit numbers in my head.
No way!! Prove it! :O
It always amazes me that, barring any mistakes that he has to go over, and re-do, he can get the answer to his 5 digit square in just over a minute.
Even the extra 30 seconds to go over his mistake is still pretty impressive
Simple Mathematiks packed in Fun Stuff is the best way to learn or getting someone to interest into

14:53 Matt Parker attempted it on Numberphile and he *almost* did it it's called a Parker square
Amazing! This kind of show can help to get kids interested in mathematics. And that would be great.
Mind blown. Definitely worth the watch!!

He's is a great teacher!!
In Germany we say THREE-AND-FIFTY for 53 :( - 20:50
+Raphael Sümpelmann That's sad xD
That's why I hate my language :(. I'm dutch
I am sorry to hear that. You should try a new language.
that's why you guys lost the war
I've just realized how useful mental math really can be...but the real question is:
*Who is the right pitcher*
First time I’ve see him make a mistake on the magic square. Not just one mistake but a couple. At least he was able to fix it

Which is unfortunate.
who doesn't love eight
wonderful
I'm reading his books, as now.. its feels like a spoil alert to watch this video
true
Give the list
I have read his secret of mental maths
This quality is so good but these kids are so young im confused
I downloaded this
this was awesome. Just bought his book :))
Fantastic ! Vow !!
Golden Ratio:-
a/b = (a+b)/a = 1.6180339887498948420 …
biggitup for the 2 digit number 108
I really had to laugh: In germany we say "dreiundfünfzig" which equals "threeandfifty" :D
Now I'm up to 9-digit numbers.
geometry makes math fun
he is doing same thing wt he did this video in all his other videos ... But in different located ...
Simply amazing! But is he good at derivatives and integrals?
His supposed to be a mathematician.... so he shld
+Marlin1290 lol, I have no words for you
There are 29 calculator manufacturers that dislike him.
Anyone know how he did the card trick at the beginning?
Yes, but I'm afraid I can't reveal it because it's a magic trick.
he did well
this is cool!!!
do you think this guy knows his times tables
Hello to the fellow people in ms Stewarts class
What the heck?! at 14:55 in row 2, thats my birthday. The heck?
22:20
Can we have this guy develop our math curriculum instead of whatever idiots came up with Common Core?
WOW
This is very easier
🙏
This is more Arithmagic.
Was it by complete chance that all the 4 numbers picked by the audiences at 5:30 are multiples of three?? so he was able to do the trick at 9:00 ??
I don't think so !!
It was by chance. I saw him perform at a corporate event and he did the same trick... but with different numbers of course. :)
animimm
Probability 1/81
For verification
No. I saw him live at an IBM conference. All numbers from the audience was random. I provided a number for one of his tricks myself.
This guy sounds like Jon Lovitz.
That 1st girl is jail bait
FBI OPEN UP!!!!!!!!
How he gets the day of the birth date?
+Sentry-19lll He's memorised every date ever ;)
+Walter Kingstone he did not memorize every date.
OFFICIALLYBINWEEVILS Oh really
+Walter Kingstone yes really
he looks like a nerd that has the power of Saitama
How is she born in 1997, She looks like 11 year old
She must be fucking 17, no way XD
basketvic99 It must've been filmed a few years ago...
Qpang S3 I found out that this was filmed in 2010. So she was actually only 12 or 13.
basketvic99 I was thinking the same XD
Is Pythagorean theorem correct ? Please just simple answer , yes or no.
yes and proven
Danijel Drnic Of course it is ... do the math! :)
I dont want to be good at math if I have to wear a tank top :-(
spare a thought for the poor kids wearing sandals!

No math here. Move along.
I am better than him. I wrote him an email, which of course he ignored. I am currently squaring 7-digit numbers in my head.
right....
Prove it. Tell us you're method if you're not bullshitting us.
MAKE A VIDEO OF IT!!
it's likely the criss cross method. Some indian woman did it with 13 digit numbers.
