My brother tried to teach me this in the 60's. At last, I finally get it. The patterns make perfect sense now. Where was this teacher when I was a child?
They used to teach this in school when I was a kid, finger multiplication as well. If you practice this method you can do multiplication in your head. I got pretty good at it. I had to get into the habit if doing ALL my math three times since I was in the 1st grade. I was dyslexic before they had a name for the condition. In other words even if you're dyslexic practice makes perfect.
Very well demonstrated, Pradeep! In case anybody is interested, it all works on the distributive property of multiplication, the principle works as follows. If you are multiplying two numbers, you can split the numbers up any way you want and then multiply each component in the first number with each component in the second number, and then adding all the results will give the correct final total. For example, 123 x 654 = (100 + 20 + 3) x (600 + 50 + 4) = (100 x 600) + (100 x 50) + (100 x 4) + (20 x 600) + (20 x 50) + (20 x 4) + (3 x 600) + (3 x 50) + (3 x 4). You can multiply these and gather the results any way that you wish. Algebraically: (a+b+c)(x+y+z) = ax + ay + az + bx + by + bz + cx +cy +cz
Yup you're right Rame A.... This trick is amazing and nice to hear that you still interested in these type of math problems... Be healthy and Safe. 😊😊😄
Thank you Pradeep, I am crying. Why didn't they teach us this way in school? You just took away years of a phobia I've had with math. Peace and health to you and yours.
I am an African American 57 year old female. I get it. I have never missed with this method. It's a good option for those who can handle change or a little challenge. Thanks so much for your help. My point is that the internet is the great equalizer. No immigration restrictions here. Just try. Until you get it.
How are you Sir Pradeep Kumar? This video was published many years ago now but still I believe that many will be impressed with this method. Thanks for sharing this technique. I hope many viewers, including me, will still learn a lot more from your channel. God bless you Sir.
This is so amazing man where have you been hiding all the time i've been looking for stars that shines without any authority to shine among other stars..... you are very delicious Mr i thank you very much!!!!!!!
These methods are a lot of fun and make good party tricks but the the methods taught in most school curricula is for the following reason. Education is not just about rote learning a method, but also about 'why?. If children don't understand 'Place Value' then they can't progress much further in the subject, which in turn limits their chances of getting a decent career. None of these party trick methods can teach 'why?'. But good teachers can teach them to children who are eager to learn more.
@@anthonywhelan5419 I don't understand how this method is faster than the traditional "slow" method... it's the same... you just added the products in your mind and started from left to right... let's do it from right to left and you'll get the exact numbers (in the 4 rows table).. but we write vertical first instead of horizontal...first digit (2x4=8)...now second digit (3×4=12)+(2×2=4)=16 (write 6 and 1 is for next digit... you can see the 2 from 12 and 4 in the second column in first method)... now third digit (4x4=16 + 1 from previous step =17)+(3×2=6)+(2×1=2)=25 (write 5 and 2 for next step... we also got 7,6 and 2 from third column in first method)... and so on... I'm not trying to be annoying... I'm just saying if you are using paper and pen then you are still doing the same thing... you are just making it more complicated for kids and make them do errors... and if you are a human calculator then it's up to you to use any method you like because you are technically a robot.
I can speak blah blah...... Gosh, I wish this had been taught 50 years ago. This is amazing. I was looking for ways to keep my brain active and decided to start over learning math , Algebra, actually anything related to math. Thank you for sharing your knowledge.
Today's' day & date: Saturday, August 3, 2019 UA-cam, you should have recommended me this video years back. Thanks for sharing this video and enlightening us with the knowledge. Love from Nepal ;)
Amazing. Thank you! The reason that I watched your video is because I am experimenting with new ideas in computing... using analog electronics and processes in parallel. Oh, I've got ideas! Lol. I have already discovered that you can multiply in parallel every digit in a grid and then add along the diagonals, and recombine by addition to create the answer in 3 parallel steps. Very fast. But now, I have created an electronics method of turning a voltage into an analog analogue of a digital signal, and then I am able to reconstruct the original voltage using another circuit that interprets that analogue signal. So, it is important to consider methods of mathematics (such as multiply) that address the MSB first, rather than the LSB. I am trying to get over cross multiplying. I know I will succeed, eventually... one day. Thank you so much for putting yourself out there. ITYKWIM .Good job!
Brilliant, sounded so technical the first time you done it... but it's so easy once you know how. Why on earth schools don't teach this way, so much easier.
This technique is truly amazing and helpful. However, for kicks, I tried some larger numbers (still only 4 digits across) and found several snags in the technique that aren't easy to figure out. I would have to work on it knowing the answer to figure out how to do it correctly. For example, what happens when cross multiplication of several digits equals a 3 digit number, and not a 2 digit number, as it did in his example. Do you carry the first 2 digits of the 3 digit number over the top of the previous digit, or do you carry on the first number of a 3 digit answer to the top of the previous number, then drop the second two digits to main number line? This happened several times in the numbers I used which I randomly picked and the answer I got was way off the correct answer. Not sure how to proceed from there. Any help anyone?
@@alsp4005Thank you but I don't think so. The long rigorous confusing explanations says otherwise or may be the person doing the explanation is making it look so. If this method is far easier it would have been adopted and widely taught in schools and colleges. I am not convinced.
@@alsp4005 More to the point, what test measures calculating speed? That's testing the wrong thing in a world with calculators and computers. I recall tests decades ago that would have more questions that you could answer but my understanding was it wasn't critical that you calculated more questions right, just that you answered enough right or guessed the approximate value and weren't super slow.
One learns a technique which is tough. Overtime practice makes the tough a habit. The habit becomes easier not the technique. Teaching of (tougher techniques) habits are reinforced in the society. The reinforcement is done by those in power (conquerors/colonizers/military/police/school boards;etc.). When a truly easier technique (TET) is introduced, the TET will be deem tougher. Those in power/society must have a change in awareness/understanding. What is being reintroduced is Vedic Mathematics. Vedic Mathematics is the TET.
This is more difficult than the regular long multiplication. Great, after reading comments praising this "very simple" method may I challenge anyone to use it to multiply 473947389439 by 382974398758. What a hoot and waste of time (and clicks !!!)
8:05 starts explaining how, 13:03 summary of steps. Like the Left to Right calculation (seems to work both directions when tried on smaller numbers). Keeping running tab in head only real challenge so if had to write it all out not much different than just 'showing' all you work.
exactly what I wanted to write: you just do more in your head and less on paper. For kids that is much more confusing and more errors will appear. Also, with bigger numbers (6-9) it's more difficult.
WOW. 🌹Superhelp for the math-challenged. Frankly, the Vedas reference.had me in awe. Extremely thankful for youtubers like you. Please keep on with this work. 👍👍👍
This is great! I'm now able with this technique to multiply two 4 digit numbers in barely over a minute! Do you have a similar method for long division?
Thank you sir,,i used it to 4digits to 3digits in same pattern by just imagining "0" is the 1st no. in 3digits then proceed to cross multiply and the same to the next step and so on and then finally i solved it. This is awesome..thank you!
I’m 60 years old and was taught the very first method he used as a kid, the old tried and true..lol But it does take up a lot of room. This is a game changer! I’m officially impressed. 👍🏻 I can’t wait to try this for myself. Thanks for this video. 👍🏻
I've been doing this method since 2009, kinda figured it out on my own. I even taught the teacher that came to the house this method. She was pretty surprised that an 8th grader could come up with this on his own.
Thank you so much sir.. I am terribly bad at mental calculation that is required to be done quickly...now am able to do it perfectly...thank you so much!!
This might be the fastest way to multiplication any large numbers but I love the oldest calculation method which I'm familiar with for almost 60 years plus, by the way, I love my 99 cent store calculator more than any method.
You know what I appreciate most about this video? You gave the original name of the technique. I never really studied Indian history because I was drawn to European history more, but that just makes India more mysterious to me because of that mindset. So you gave the name of the technique, wrote it in ... whatever the script is called... and then in English with an explanation of the lines above the letters. At some point in your other videos do you explain why the original script also had a line across some of what I am presuming are words? All in all, great job. I wanted to learn a bit of math, which I did. I also learned a little tidbit about a place that I think is really cool and will serve to give me one more reason to finally do some thorough research on Indian history. As far as I can tell, I already won today and its only 9.40am.
HELP! If we do a number (ex: 7,961 * 4,385)...how do I carry over the 3 digit number when we get 1/2 way through? ...the 129? I've tried leaving the 12 up top as a remainder...and just the 1 with the 29 down below and get it wrong both ways.
I donno why some youtubers keep explaining trivial issues more than they need, and when they come to the main point they go very fast! I think, here, because he was trying to prove that the second way is faster.
