For all of you wondering how to do it for 4+ digits here's how. For 4 digits, you do the same he did up until the 3rd digit. When you get to the 4th digit (counting from right to left) you multiply the 4th digit with the 1st digit, the 3rd with the 2nd, the 2nd with the 3rd, and the 4th with the 1st. After that you repeat the process you did with the first 3 digits with the last 3 digits. For 5 digits, you do the same up until the 4th digit as explained before. For the 5th digit you'd do the same as before. The 5th digit with the 1st, the 4th with the 2nd, the 3rd with the 3rd and so on. I know the explanation might be confusing, but this is the bets I can do. :)
Thank you so much! It is kind of similar to when you are learning how to quickly do the "multiplication by 11" trick and you then find the "multiplication by 111 trick". The same concept, but modified because of the number of digits.
and now your 4th grade students are going to look like geniouses compared to adults XD. this right here is the magic of this channel, teaching the teachers
Unfortunately, instead of this quick method, our kids are forced common core.... Which means 4 sheets of paper and 15 minutes will be used to get the same answer
@@krw73 while the common method is less efficient, it is necessary, it gets kids to memorize all forms of whole number multiplications from 1-10 and has bonus addition practice as well. I'm sure we all are extremely quick at multiplication and addition of because of this. Higher grade classes should definitely adopt this though
That's because the book make everything a painful exercise in pulling teeth, using very long rectal instruments. Whenever I tutored anyone in math, my first step in the process was always, "It's easy". And then I proved to them that it really was easy. You just have to look at it the right way.
LIFE CHANGER! this changes math for real! I've been struggling with my 3 digits and more! thank you so much!!! I'm never going to see math how I used too!
I'm east indian this is called vedic maths which basically originated from ancient India and it's sad that our schools in India does not teach us, this not part of our curriculum. We had to join classes after school and pay extra for them. Edit: It's real fun, easy to learn, and improve your math alot!
I want to thank you for improving my teaching. Maths is my weak link. I am absorbing all of your films. These tricks (as you call them) are the answer to my struggles AND they make total sense. I have never heard of many of these methods. I was taught in a strict, long, drawn out method of doing any math work. It was boring, overwhelming with steps and procedures and no one could explain the logic to me. THANK YOU THANK YOU THANK YOU. Whether this is an old method or not it is new to me and I feel confident now. I am ready to be a strong math teacher. I realise that these films were made quite a while ago but I do hope that you are able to get this message. Truly thanks! -Carla
Love this channel found it a few years back. I’ve loved math since I was in junior high. Once I got to algebra I hated it but had a tutor that made it make sense and ever since I loved it and seeing all of your tips and tricks make it even better
I feel ashamed in math before when it comes to Mathematics , my teacher on elementary said I'm difficult to teach, well... They are not teaching me well I guess, this video was just 8:15 minutes but how did I understand this more than what she thought .
@@ADAPTATION7 Agreed. What a horrible thing for a teacher to tell a student. I had my share of them as well. We all have. Story time. I had a geography teacher who hated me. Seriously. At the beginning of the year he gave us all a comprehensive test on geography, covering things he hadn't taught us yet. I did fairly well. Third highest. Then at the end of the year he gave us the same test. I was at the bottom of the class. He finally ranted on me about how much of a worthless student I was. He said, At the beginning of the year I gave that test and you were at the top. At the end of the year you got about the same score. Everyone passed you up and you were at the bottom. What do you think that tells me? I said, It SHOULD tell you you're a lousy teacher. Clearly I picked that information up from other teachers along the way who were much better than you. But you taught me nearly nothing except how bad you are at teaching. He didn't have an answer for that. He just glared at me. Go ahead and stare, loser. I'm great at learning, but not from you. You sir, are the lowest common denominator. You are the cylinder that's not firing. Why are you even a teacher? You should be digging ditches or something.
It's Vedic maths bro ,it ll work don't worry ,this is created by Indians ,and used by all countries except india ,that's why India is lagging back,one more tip,learn Vedic maths,u can do 3*3 digit multiplication with u hands in ur mind ,faster than this ,but little hard to learn
I’m teaching my children your methods. They don’t say “I’ve been taught this at school” They think it is very helpful which is why I showed them. One day I may get a thanks from them.......
Well children’s moods change a lot as they grow older. They might no be grateful yet but I assure you your children will be grateful when their older and proud to have such a helpful father
Oh so my secret is revealed haha. Btw, ever since I was elementary, I really loved Mathematics subject. So when I got in highschool, there is this Match teacher that always do some exercises where we are grouped by column in our classroom and compete with each other in computation. Whoever got the fastest and correct answer get 1pt. And since I love mathematics, when I get home I study the problems and go back to them and experiment on the numbers how to get the same answer at the easiest or least number of solutions/steps to get the answer. And this is one of them hehe. Its good we have youtube now to teach students. Mathematics is so fun. :)
You basically did learn it in school. You’re still doing the same thing, but instead of breaking it down in rows and then adding, you’re summing those parts up as if they are broken down by place value. They probably don’t bother to teach this in school because they would have to spend the time explaining Why it works, and students would get so caught up in trying to recite the patterns they’d forget how to do multiplication altogether. Like, they’d either have to resort to the standard way.... which they know is tedious and may not have practiced as much, or this method, which works smoothly but if you haven’t done it in a while it could be easy to forget how to do it and why it works. ....given the choice, they’d try really hard to do the quick way, especially in a pinch. And if they forgot how to do it, this could leave them completely unable to do the problem.
I didn't expect this to actually help me and be this easy. It feels complicated at first but once you memorize the steps one by one it's actually super helpful
I actually discovered/learned this math logic on my own when I was in high school.... But have since forgot it...and found myself here looking for it...I had math teachers turning their heads when I would give the answer right after they finished writing it on the chock board...one time the teacher even grabbed a calculator to check my answer... This is hands down the best way to do multiplication.
Thanks for sharing your knowledge. Wish I learned this before. I used to hate math but now I am beginning to love it. I’m 49 years old and still learning. 😊
I appreciate this, I was never good at maths, and honestly part of it was because of the fact that teachers complicated things, I'm glad I finally found a way to get things done quickier, good video.
Thanks so much for sharing these tricks! I love them! I wish schools teach students maths this way... the traditional methods are very slow and it takes the fun out of math
Sir, I cannot thank you enough for this. School never did me justice when it came to learning math, but you did with just one video. Thank you so much for all that you do❤
This is what we should be taught in schools...this is way more practical in real life than what we do in schools....And thanks to this channel it helped me a lot🙏♥️
I have used the same trick for some time but work from left to right. I put the carrys underneath and add them at the end. This can give an increasingly accurate estimate as you go along. You can then rule out answers that are going to be too high or too low.
Another way which separates out the computation from the summation is to write the number sums separated by a comma (to denote the power of ten column one is working with i.e. units, tens, hundreds etc) so the carry is contained between the commas (called 'open numbers') until completion when the summation process compacts the number down to just single digits between each comma and pushes any carries into the next comma column at which point the commas can be removed and the number becomes a closed number (which is the normal hind-arabic number with each digit representing the powers of ten value). The advantage of this approach is that it can be done from left to right or right to left but it also provides a clear audit trail of how the student arrived at their answer and where they may be making mistakes. Is it in the multiplication process or the carry process? As one masters the process it can be done faster and even mentally. So 213 x 323 becomes 6, 4+3, 6+9+2, 6+3, 9 => 6,7,17,9,9 => 6,8,7,9,9 => 68799 [N.B. I have used '=>' to represent equivalence or becomes] For estimating you just stop at a significant point & enter the relevant number of commas or zeros to get your approximate number.
@@sr9fire Thank you. The Vedic mathematicians use a slash but Norman Wildberger uses a comma and calls this form an open number; the comma separating the 10's powers columns. Its no different to how we handle money and I can have many different ways of 'making up' the same amount of money but there is only one way that we denote the actual sum i.e. in its closed number form. I find this method very useful when doing left to right multiplication but it works right to left as well. We need to bring back the playfulness of doing numbers which is what I find in the vedic approach.
Just want to thank you so much for your lessons. As a parent and former kid (lol) I've always hated the schools' convoluted methods of teaching math. Been teaching my 9yr old a couple of your methods and now he's understanding and doing the problems faster with little to no mistakes. (I've also been retraining myself too!) I'm forever grateful for your lessons!
Combine this with the major system (memorize numbers by converting them to consonants) and you can do this in your head. "Write down" the finished digits by turning them into words. 2=hen, 12=tuna, 212=nothing, 6212="shined on", etc. Carry digits on your fingers (thumb=5) You have a tens hand if you need it. To really show off (unless you're being graded), you can link the answer words to either rhyming pegs or memory palace locations. You can hand the paper back blank, and then call out all the answers.
Several of the tricks you've shown were taught during the higher grade school years (7 thru 12 in the US) 50-60 years ago. At least they were where I schooled. Over time I've forgotten most of them, though. Thank you for taking the time to post them.
As a subscriber, I'd subscribe again if I could; this is brilliant! Now i know why when i was struggling way back as a ten year old and looked around and saw the 'smart kids' with their pens down and staring out the windows (who had finished the calculations) while the rest of the class struggled on. The teacher of course had no understanding of how to multiply. I am at 57 enjoying and understanding mathematics so much!!! Why isn't maths taught like this at school, it makes better sense, less chance to make a mistake.
Does help people with slow learning too or forced slow learning with what the school does with deaf student in hearing schools. Thanks for not being afraid to teach to all hearing or deaf or slow.
Thank you, sir! I'm back in college after many years since graduating from hs, so I needed many refreshers on my math. This is even better than what I've learned, really wished I could've learned this back then but it's just as good to learn now!
High school math classes always got me frustrated and this is way I did so poorly. Your methods are something I would have LOVED to have. However, I enjoy learning the 'secrets' now. Thanks! You're a great teacher.
Absolute genius! I have read all kinds of articles about Nim, they talked a lot all those difficult terms, mythologies, from “Moon” to “Earth”, then to the “Mars”, but you still not get the basic ideas. After this video, you get the whole Nim ideas immediately! And you can easily add some binary numbers once you get the basic ideas. I do not why people often explain simple things in over-complex terms, in a really complicated way?
Finally, someone who does it the way I do maths ✌️ Two digit number multiplication (10a + 1b) * (10x + 1y) = 100ax + 10 (ay + bx) + 1by Three digit number multiplication (100a + 10b + 1c) * (100x + 10y + 1z) = 10000ax + 1000(ay + bx) + 100(az + by + cx) + 10(bz + cy) + 1cz Just solve the algebraic expression and you will get the proof for the steps explained in the video. It is very neat.
I’m a gran and to keep my mind ticking I just love and enjoy learning maths again with all the tricks... I’m better able to explain or help me grandchildren. Fantastic
Its just an extension of the two by two and three by three pattern. See if you can work it out yourself & then check your answer by doing the long (slow) multiplication method. You will learn it better if you try to work it out yourself.
I hate math since I was a kid. Because everytime I see numbers i feel sleepy and my mind is not working. But this video helps me a lot. I can already answer the test quickly. It's just a technique. Thank God I found this video. You deserved a lot of subscriber🥰
If I hear a school child saying again, “I’ll never use this in real life” I’ll gladly tell them they’ll have a limited lifestyle. Then justify their possible routes in life & why they should see more of your videos. Everything comes down to numbers.
If you have a job that doesn't require mathematics then they're probably not paying you much. That's OK because you're bad at math and won't notice. If you want a job that really pays you need to learn a secret language. Lawyers talk in lawyerese. Doctors talk in doctorese. Programmers, engineers, physicists, etc. all have their own languages and tell jokes that other people won't understand.
omg where was this method in grade school....Here I am 40 years old and I forgot how to multiply by hand....and this video comes up. I am so, so grateful
Thank you so much for this! I Have a math mock exam coming up and I've been doing well in other topics besides multiplication and this would really help me
Vedic maths was 'discovered' by Jagadguru Swami Bharati Krishna Tirtha, Shankaracharya of Govardhana Pitha (1884-1960). Whilst the method may well have been taught much earlier there is evidence that this method was used in a number of different cultures and may be the origin of the 'times' symbol we use to denote multiplication. The oldest known mathematicians are currently the Babylonians who counted in base 60 but used extensive tables to help them do their computations (like times tables). We still use the same system today (when we calculate the time in minutes & seconds). 100,000's of their tablets which were dug up in the 1920's have still yet to be translated. ua-cam.com/video/i9-ZPGp1AJE/v-deo.html
This is a neat alternative, but I don't find it more intuitive or faster, for that matter, than the "normal" way of written multiplication thaught in school. Some of these tricks, shorthands etc. are really good though!
there are other channel which are good and helpfull as well, but i find yours the best as you make it very easy n simple and explain,break down[presentation] very well,.

i became the best bo in class of math... U GOT A NEW SUB MAN
Super….I just showed my daughter and grandson this channel……this is very important for them to comprehend…..
Several of the tricks you've shown were taught during the higher grade school years (7 thru 12 in the US) 50-60 years ago. At least they were where I schooled. Over time I've forgotten most of them, though. Thank you for taking the time to post them.
Brilliant - takes some getting used to but gosh it is so much easier I now have joining dots on the brain - lol. Thank you!
tecmath: did you do it faster than me?
me: pauses the video
does calculation
and says "YES!!!!"
As a subscriber, I'd subscribe again if I could; this is brilliant! Now i know why when i was struggling way back as a ten year old and looked around and saw the 'smart kids' with their pens down and staring out the windows (who had finished the calculations) while the rest of the class struggled on. The teacher of course had no understanding of how to multiply. I am at 57 enjoying and understanding mathematics so much!!! Why isn't maths taught like this at school, it makes better sense, less chance to make a mistake.
Thanks. I literally just came across your video. What are the steps for multiplying 4 digit and 5 digit numbers?
That's nice
Does help people with slow learning too or forced slow learning with what the school does with deaf student in hearing schools. Thanks for not being afraid to teach to all hearing or deaf or slow.
Thank you, sir! I'm back in college after many years since graduating from hs, so I needed many refreshers on my math. This is even better than what I've learned, really wished I could've learned this back then but it's just as good to learn now!
I don’t know how you think of this you’re so smart this channel is treasure
High school math classes always got me frustrated and this is way I did so poorly. Your methods are something I would have LOVED to have. However, I enjoy learning the 'secrets' now. Thanks! You're a great teacher.
Absolute genius! I have read all kinds of articles about Nim, they talked a lot all those difficult terms, mythologies, from “Moon” to “Earth”, then to the “Mars”, but you still not get the basic ideas.
After this video, you get the whole Nim ideas immediately! And you can easily add some binary numbers once you get the basic ideas.
I do not why people often explain simple things in over-complex terms, in a really complicated way?
"Mom I think we can sue my math teacher"
Finally, someone who does it the way I do maths ✌️
Two digit number multiplication
(10a + 1b) * (10x + 1y) = 100ax + 10 (ay + bx) + 1by
Three digit number multiplication
(100a + 10b + 1c) * (100x + 10y + 1z) = 10000ax + 1000(ay + bx) + 100(az + by + cx) + 10(bz + cy) + 1cz
Just solve the algebraic expression and you will get the proof for the steps explained in the video.
It is very neat.
Thank you so much for these videos it has been very helpful.🤩
This is Vedic Mathematics that you are teaching through your video. Very nice work great job sir
I heard stories growing up of buyers in tobacco warehouses that used this to figure weights and prices of tobacco.
I’m a gran and to keep my mind ticking I just love and enjoy learning maths again with all the tricks... I’m better able to explain or help me grandchildren. Fantastic
Can you show 4 digits time 4 digits and 5 digits. Is it the same method or different?
Its just an extension of the two by two and three by three pattern. See if you can work it out yourself & then check your answer by doing the long (slow) multiplication method. You will learn it better if you try to work it out yourself.
that is why it gets harder than ordinary old way....
One of the best Channels on UA-cam!!!!!
This is a cool math trick. I will need to come back when I’m not stoned and watch it again.
Man oh Man ... why wasn't I taught this at primary school 50 years ago? Thank You so much for sharing!
I learned a matrix method. It is in my first math Video in the "SCHOOL TIPS" Playlist.
you dont know how much this really helped me, thank you so much, new subscriber here!
Really appreciate this video, you've given me an edge in a really important test coming up - I thank you!
Amazing. The logic is solid. The technique for how they came up with this is mystefying.
This use on 4x4 is still the same right? Just one more step
Lollipop .... He made a video 7 years ago basically adding 1 more steps and then reversing ...

there is the link^^^
@@zaydxn2735 oh ok, thanks so much for the link!!
I hate math since I was a kid. Because everytime I see numbers i feel sleepy and my mind is not working. But this video helps me a lot. I can already answer the test quickly. It's just a technique. Thank God I found this video. You deserved a lot of subscriber🥰
If I hear a school child saying again, “I’ll never use this in real life” I’ll gladly tell them they’ll have a limited lifestyle. Then justify their possible routes in life & why they should see more of your videos. Everything comes down to numbers.
If you have a job that doesn't require mathematics then they're probably not paying you much. That's OK because you're bad at math and won't notice.
If you want a job that really pays you need to learn a secret language. Lawyers talk in lawyerese. Doctors talk in doctorese. Programmers, engineers, physicists, etc. all have their own languages and tell jokes that other people won't understand.
I used this in my computer architecture class for multiplying in binary and hex, very quick and to the point
Nice Tecmath!
Btw first!
Hi?
Hi
HI
omg where was this method in grade school....Here I am 40 years old and I forgot how to multiply by hand....and this video comes up. I am so, so grateful
Bruh😂😂 I kept stopping at the beginning bc I thought that u had already started
dude you are just a freaking life saver. absolutely amazing. pure genius. thank you so much for sharing. I wish they taught this in my day
We want a video about how to multiply 4 digit number
Please sir
Thank you so much for this! I Have a math mock exam coming up and I've been doing well in other topics besides multiplication and this would really help me
I already knew this congrats!
Btw i am an scientist,
Mathematician.
Tech Master that’s very cool
This is vedic math, I also knew, my father told me this.
I cant trust that cause you said im an scientist
bro you are a life saver way better than average teachers thanks so much! didnt even take long too understand and its way faster than other ways!
This is Vedic maths.
Yes and no. Calling it "Vedic" is a misnomer.
Vedic maths was 'discovered' by Jagadguru Swami Bharati Krishna Tirtha, Shankaracharya of Govardhana Pitha (1884-1960). Whilst the method may well have been taught much earlier there is evidence that this method was used in a number of different cultures and may be the origin of the 'times' symbol we use to denote multiplication. The oldest known mathematicians are currently the Babylonians who counted in base 60 but used extensive tables to help them do their computations (like times tables). We still use the same system today (when we calculate the time in minutes & seconds). 100,000's of their tablets which were dug up in the 1920's have still yet to be translated. ua-cam.com/video/i9-ZPGp1AJE/v-deo.html
Thanks very much. You have clear explanations (why) along with methods (how) which many other channels lack. for that reason, I've just subscribed :)
This is a neat alternative, but I don't find it more intuitive or faster, for that matter, than the "normal" way of written multiplication thaught in school. Some of these tricks, shorthands etc. are really good though!
It’s 9pm and I just helped my my 11yr old daughter MasterTrust concept - thank you
Why doesn't this replace the time consuming and complicated multiplication steps that we learn at school?
i think this way takes longer and more calculations in total.makes no sense .there are people trying to find hot water...
Its actually BEAUTIFUL because it's so logical. It's comforting!
This is really helpful because I am studying for the scholarship Exam in June, Melbourne high exam.
amazing tricks, loving you way of teaching, thanks
Loo I'm 9 and I knew this already (watched a lot of UA-cam )
flexing wont make u smarter lol
I love you man, i'm starting to love Math, THANK YOU!!
Everyone: Indian guy on UA-cam yada yada
This guy: Hold my beer
Hey! I love beer!
You are a genius! This was very helpful while doing calculations in Physics and Chemistry!
Thank you so much! I've been struggling with multiplication for so long, and this makes so much more sense then any teacher has taught it. Thank you!
there are other channel which are good and helpfull as well, but i find yours the best as you make it very easy n simple and explain,break down[presentation] very well,.
Hmm interesting
Kedalini ikr hi
WOW! Love your multiplication tricks! Thanks so much! I love Maths! Lots of love and Shalom
