Diwana Kavi still it takes LOTS of practice. Let's say now we know how it works, then how long do you think you need to practice it to solve 8463 squared that fast?
@FACTS & knowledge He's still very well at articulating and explaining it. It really doesn't matter whom invented the method; if they don't have the platform or aren't able to explain it in a way that is easily conveyed and understood to the audience, then it is for nothing. This guy is a great proxy for the original work. Also, faulting this guy for teaching the methods in said book, is akin to badgering any other math teaching video for copying the teachings of the ancient Babylonians.
@Hitesh chourasiya maybe he discovered it on his own? It's not so hard to find out this "trick". Heck, I discovered this myself in high school. For a professor like him? Fnding this would've been a piece of cake
For those of you who would like the last problem in slow motion: 4913^2. He chooses 87. so now it is 5000x4826=5x4826x1000=(5x4800+5x26)x1000=(10x2400+10x13)x1000=(24000+130)x1000=(240130)x1000=24130000. Memorizes 130000=Dime. (Probably his mnemonic involves rules where 1 stands for nothing, 2 stands for something, 3 stands for dime etc. and then he combines them. So for example if it was 23000 it would be some other word plus Dime). Now he does 87x87=90x84+3^2=(9x84)x10+3^2=((9x80)+9x4)x10+3^2=(720+34)x10+3^2=(756)x10+3^2=7560+9=7569 now add that to 24000000+Dime (which is 130000)+7569=24137569
Except for the slight typo (240130), perfectly summed up. Although I do think he went around 5000x4826 a different way: 5000x4826 means 4826/2 and add 0000 so 24130000. Feels easier and quicker.
Nice job! One slight correction. He said he was doubling 4826. As he referenced earlier with doing 51^2, he's dividing it by 2. So, he said doubling for 4826, he's dividing it by 2 to get 2413 (x 10) = 24,130... Keep the "dimes" is using peg system. d = 1, m = 3, s = 0.
When this guy was a student at Mayfield High School (Ohio), he was brought into my 8th grade algebra class at Mayfield Middle School (1978-79 school year) and taught the class his methods for squaring numbers, and I still use them today.
For those of you watching this and thinking that you'll never bee able to do it it's because you need to improve your basic math skills first. You may have to practice 3 by 3 subtraction, 3 by 3 adding and 2 by 2 multiplication. Just time yourself on 20 problems in each subject and if you're around 1 to 2 minutes for the 20 problems you're ready to start learning this method for squaring.
You sir just taught me something no teacher ever could. I literally just successfully found the square route of 76 and checked it to be correct. My cat was jumped as I shouted YESSSS! haha
There is no magic though. This is simply (a)^2-(b)^2 = (a - b)( a+ b). Adding b^2 both sides: a^2=(a-b)(a+b)+b^2. Anyways, this video is very helpful. I appreciate him for putting this up.

We can generalize the equation at 8:30 to multiply two arbitrary integers A and B. Notice that (A+d)(B-d) = AB-dA+dB-d^2 = AB - d(A-B+d), hence AB = (A+d)(B-d) + d(A-B+d), and notice that if A=B we retrieve the eq. at 8:30. For example consider: 26*33. The nearest easy number is 30, so subtract 3 from 33 and add 3 to 26: 29*30. Then add 3*(26-33+3) = 3*(-4), so: 26*33 = 29*30 - 3*4 = 870-12 = 858.

I always thought I'm best at mathematics and then I saw you. I'm no where near you, I know about tricks and all but doing it that quick in mind is something I won't be able to do. Respect sir 🙏
You are an amazing professor. Hopefully I can find a video of you teaching us how we can find the root of numbers without using calculators. I’m also looking for tricks for division problems.
i worked out that x^2 + y^2 +2xy= the square of any number. if the number is (xy)^2. hence 51^2 is 50^2 + 1^2 + 2*50*1. This works equally for every number. So a 3 digit number can be expressed as 124^2= 120 ^2+4^2 +2*120*4 Although id never get to it as fast as this practitioner, and wonderful educator x. however there must be a formula for 3 digits, 4 digits as well.. just never worked it out yet..
Wouldn't the x^2 + y^2 +2xy method defeat the purpose of squaring any complicated number more than 100? I mean, you still have to square a 3 digit number to find the square of another 3 digit number. Like, to find 124^2 you have to do 120^2. Also that method is pretty simple because it's basically the regular (x+y)^2 formula.
I only tried doing it this way after about 3-5 years of doing it my own way, which produced the answer in exactly the same time, but had a few differences. i.e. multiply 87 by 80 then add 87 times 7 to get 7569. I had mastered this in the 4th grade and have to use it because rewiring the synapses in my brain would make me slightly slower. But i will def. remember the method shown in the video. Thanks for the useful tips. Art Benjamin you are an inspiration to us all.
you are a genius i surprised my teacher like when she called me dumb.. and she asked me square of 19 and we get 361 and everyone clapped but then she asked 99 and I answered after couple of seconds 9801 and I gained my respect 😎
Thank you so much for this...!!! My stats teacher is going to piss herself when I can complete half of a one-way anova by the mind alone!! hehe....Now to find the video on how to multiply 2 digit numbers like 24 x 39 etc...
start from left to right, we have 2 x 3 (20 x 30) so we have 600 record the 600 in your head and continue, 2 x 9 (180) add to 600 is 780 and add 3 x 4 (120) 780 + 120 = 900 ok still have the 900 in your head and add 4 x 9, 936. this is the answer, the method is multiply straight, cross, straight, I X I. so if we have 43 x 67 we start with 4 x 6 = 2400. and we add 4 x7 = 280 we have 2680 and we add 3 x 6 is 180 so 2680 + 180 is 2860 + 3 x 7 = 2881
Same I dont concentrate either I remember back in first grade my teacher used to teach like take 1 in your finger and 6 in your mind and shit which I did not use to calculate I used my brain
The teacher used to give us a whole page of simple maths as HW in first grade and I hated HW so I did it in the class itself with my friends i calculated so fast that after i finished my friends had completed 2 columns out of 10
I spent a few months pondering about it and no joke i kind of figured it out on my own.. But there was always something missing.. Your video brought my memories backs RN explains where i went. wrong.. Thank you for sharing this

We can generalize the equation at 8:30 to multiply two arbitrary integers A and B. Notice that
(A+d)(B-d) = AB-dA+dB-d^2 = AB - d(A-B+d),
hence
AB = (A+d)(B-d) + d(A-B+d),
and notice that if A=B we retrieve the eq. at 8:30.
For example consider:
26*33.
The nearest easy number is 30, so subtract 3 from 33 and add 3 to 26:
29*30.
Then add 3*(26-33+3) = 3*(-4), so:
26*33 = 29*30 - 3*4 = 870-12 = 858.

however there must be a formula for 3 digits, 4 digits as well.. just never worked it out yet..
also worked out that 3 digit numbers are worked out by x^2 +Y^2 +Z^2 + 2 ( XZ+XY+YZ).. interesting series. Unlike baseball, which is just rounders

24 x 39= 30 x 24+ 9 x 24 =936 :)
start from left to right, we have 2 x 3 (20 x 30) so we have 600 record the 600 in your head and continue, 2 x 9 (180) add to 600 is 780 and add 3 x 4 (120) 780 + 120 = 900 ok still have the 900 in your head and add 4 x 9, 936. this is the answer, the method is multiply straight, cross, straight, I X I. so if we have 43 x 67 we start with 4 x 6 = 2400. and we add 4 x7 = 280 we have 2680 and we add 3 x 6 is 180 so 2680 + 180 is 2860 + 3 x 7 = 2881
good job!
Damn, people like you that spread your knowledge to others are one of the greatest kinds of people
You teach how actually mathematics works. Excellent sir.
Holy Crap ! I've been doing math in my head this way without even knowing I was doing it this way ! Maybe I'm a math genius & didn't even know it ....
Same I dont concentrate either I remember back in first grade my teacher used to teach like take 1 in your finger and 6 in your mind and shit which I did not use to calculate I used my brain
The teacher used to give us a whole page of simple maths as HW in first grade and I hated HW so I did it in the class itself with my friends i calculated so fast that after i finished my friends had completed 2 columns out of 10
Awesome... Now i can show off by squaring numbers faster than a calculator 😂😂
A simple yet brilliant trick! 👏
Wow, I'm a math genius now. You're amazing man, this is so helpful, I can flex on everyone now
You are a rockstar
Easy right? How can someone be able to do this 3-steps in his mind in 1 second lol! He is amazing!!!
Excellent sir, really excellent.
TH-cam is a nice platform to learn just because of awesome teachers like you.
I spent a few months pondering about it and no joke i kind of figured it out on my own.. But there was always something missing.. Your video brought my memories backs RN explains where i went. wrong.. Thank you for sharing this
you made things much easier to understand. thanks
Sir l am also a mathematician. YOU ARE MY INSPIRATION
I don't know why I find mathematics like a joke it always feel me happy and joyful
Very nicely explained
Even a layman can understand
Wow man
How do he calculating too much in mind ???just amazing men.
awesoe. thank you so much sir.
Hi
He’s so adorable. Definitely learned a new way of squaring!
You are such a gifted person
Love from India.
Genius
Genius guy! However, this video called me dumb in so many ways 🤦♂️
It's Vedic math brother 🇮🇳
1.एकाधिकेन पूर्वेण
अर्थ: पूर्व वाले से एक अधिक
प्रयोग: आवर्ती दशमलव भिन्न[recurring decimal fraction],वर्ग ज्ञात करने में,आंशिक भिन्नों द्वारा समाकलन[integration by using partial fractions].
उदाहरण: --वर्ग निकालने के लिए--(यहाँ केवल 5 से अंत होने वाली संख्याओं की बात की जा रही है)--
25 का वर्ग:यहाँ पूर्व का अंक(संख्या) है 2 .----->2 का एकाधिक है 3.
अब अंतिम हल है 2x3\25------->वर्गफल के दुसरे भाग में हमेशा 25 ही होगा.
इस तरह 25 का वर्ग=625.
35 का वर्ग=3x4\25=1225,
175 का वर्ग=17x18\25=30625,
995 का वर्ग=99x100\25=990025.इत्यादि.
Thank you Benjamin.
I'm Carlton, secondary school maths teacher in Cameroon.

@@justsomeguy892 yummy
The way he speaks about his work is so interesting
This is why we call teachers the maker of the nation.
WOW!!!What a genius!
I love this trick. Thank you so much!
sir I'm from India you are great sir
Arthur Benjamin: Add from left to right
Teachers: *THAT'S WRONG*
Exactly...my maths teacher always told me right to left
How I wish this kind of videos were around when I was suffering from math...
The information you hold is as gold to humanity...
He is so adorable. I definitely learned something new!
You are using vadic mathematics sir good to see...
American also know about indian theoryes
virender goutam it doesn’t take a fucking genius to figure this out. Newton invented calc and I see Indian are using that just fine as well. That actually required some real thinking. I could make one of those square things up for cubics just as easy
Basic algabra brah
I enjoyed and learned. These are the most important thing of this video.
watch my maths tricks to learn something.
My man is so passionate about squaring
