The magic of Vedic math – Gaurav Tekriwal

The magic of Vedic math – Gaurav Tekriwal

Translator: Andrea McDonough
Reviewer: Bedirhan Cinar Nameste. I’m from India, and India is one of the oldest civilizations in the world. It has contributed to the world concepts such as yoga, ayurveda, spicy chicken tikka, and Vedic math. Vedic math is one of the world’s easiest and simplest way to do math. We are going to combine together and do some number crunching today. So what we are going to first do is multiply by 11. We’re going to do it together, so if you blink, you’re going to miss it. So just watch it, OK. So we’re going to do 32 times 11, OK. So we split 3, and we split 2, and we add 3 and 2 and paste it on top, and we get the answer as 352. That’s it. Let’s try another sum. 45 times 11. Let’s hear it. Exactly, that’s 495. And 75 times 11. So it gives you 7,125, 1 gets carried over and it becomes 825. That’s how simple it is. OK, this is the principle behind it where a is the coefficient. Let’s move on. OK, now what we’re going to do is the base method. OK, this is used to multiply numbers very close to the powers of 10, like 10, 100, 1,000, and so on. So we have a sum here, say 99 times 97. OK, now tell me, is 99 more than 100 or less than 100? Less by how much? So we write minus 01. And 97 is less than 100 by how much? So we write minus 03. So what we’re going to do is we’re going to cross subtract and get the first part of the answer, like this. We’re going to do cross subtraction. 97 minus 01 would give us 96. and we multiply 03 times 01 vertically, and we get an answer of 03. Let’s check another sum. Try and do it yourselves. We got 98, which is, is it more than a 100, less than 100? By how much? And 97 is 3. So we got 98, we go crosswise, we got 98 minus 3, or we can do 97 minus 2, they’ll all give you the same answer. So that would give us 95. And the second part would be 06. So that’s our answer. OK, let’s take a bigger number. Let’s try this one. Here the base is 1,000. So we got -004, and 997 would be -003. We go crosswise like this, and we get 996 minus 003 would give us 993, and 004 times 003 would give us 012. And that’s our answer. Thank you. 14 times 12. OK, here the base is 10. OK, so is 14 more than 10 or less than 10? More, so we got plus 4, and 12, we got plus 2. Again, we apply the same rule, so we do 12 plus 4, which gives us 16, like this. And we multiply 2 and 4, that gives us 8. So now, all of us here, we’re going to do mental squaring, OK. Everybody is going to participate here, and we’re going to do squares of numbers more than 100 mentally right now. So we got 101, OK, now visualize on the board, what’s going to be on the right hand side. Plus 01, so we got that. OK, now we add plus sides, right? Yes? No? So we got 101 plus 01, that would give us 102, and, see here, like this. And 01 is getting squared, right? So that would give us 01, and that’s your answer. Try the next one. Let’s try 102 squared. Let’s try, everybody. So 100, so 102 would be 10404. OK, now the next one, try it everybody together. I’ll give you 5 seconds. OK, let’s say it together, let’s say it together, OK. [10609] 10609 and that’s the answer. Woo! 104 squared, how much would that be? Calculate it, 5 seconds. Come on, girls in the back. OK, so the answer would be 10816. OK, let’s do the next one: 105 squared. Oh, no, no, no, no, we’re going to try over, we’re going to try over, OK? OK. I’ll give you 5 seconds, just think about it. OK, now we’re going to go, OK? 11025. OK, let’s going to do the next one, 106 squared. Try it, come one, everybody, it’s simple and easy. [11236] OK, let’s do it one more time. 11236. Now 107, think, hold on, don’t say anything out loud, just think mentally, 107 squared. OK, now let’s say it out loud. 11449. And 108 squared. [11664] Fantastic, give yourself a round of applause, come on! And this is the principle behind this, where a and b are the excesses or the deficiency from the base. I’m going to teach you in Vedic math, there are 16 sutras, or word formulas, OK. They are very visual and one of them is called, “vertically and crosswise,” through which you can multiply any number by any number in a single line. So I’m going to do a two-digit by a two-digit multiplication. Let’s do this. So we got 31 times 12. OK, so we’re going to apply the vertically and crosswise sutra. So we’re going to do like this: vertically, and then we’re going to go crosswise, and then we’re going to do vertical again. So, 2 times 1 gives us [2], 2 times 3 gives us [6], and 1 times 1 gives us [1]. 6 plus 1, [7]. 1 times 3 gives us [3]. And that’s it, and that’s our answer. No more tedious calculations, no more going through the rough work, it’s simple in one line. I want to show you a sum again, this time with carry-overs. The same formula, all of us here can do this, OK. Same formula. So let’s get started. 4 times 2 gives us [8]. OK, now we go crosswise like this, so we’re going to multiply 4 times 1, [4], and 3 times 2, [6] 4 plus 6 gives us [10]. So we put down 0, carry the 1. And 3 times 1 gives us [3], plus 1, [4]. Exactly, that’s our answer, 408. OK, thank you for being such a participative audience, and we had a great time number crunching. Now I want to end with a question: whether you’d like math to be dull or boring, or fun and interesting? The choice is yours.

  1. If this tought in my school. So I could do easily mathematics by these tricks. But why these vedic mathemetics dont teach us in schools.

  2. Im sri lankan and it is said in our tales that the british burned out mathematics,physics,astrology and sciences books written by sri lankan scientists years ago – when those books were stacked on – it is said that the lot was bigger than 4 tuskers .

  3. India got many things in ancient time but we cant store them and now we inspired from other country we want knowledge from other country and the thing is that mostly information are derived from India and labelled from others though India have all their own thinks and things i think that ancient India was more swadeshi (country's own things) than now we falldown by the time of slavery came………sala kutta ghori gazni aur angerj sab barbaad kar diya!!!!

  4. How is this vedic math in this video? It's just patterns of the steps forming normal arithmetic calculations. Also instead of memorizing different patterns for different patterns, get a calculator and do the meaning part of math.

  5. American/ British: Wow! This is cool. Why don't they teach us this?
    Indians: started political war
    PS. Excellent!

  6. If everyone get best education then who will clean our roads, gatar , who will driver,naliwala , newspaper wala, majdoor
    If we give best education to every indian then we will face lot of competition

  7. British destroyed India's education system,, in some pockets these are left ,, thanks to learned brahmin who somehow preserved in their minds and thought to this generation,, slowly things are changing one day will regain our lost glory

  8. Fact is that Most of Indians don't know What they have…and this all indians ancient techniques is used by all Nonindians ☺️Feel sad For my Country…….🇮🇳😘

  9. Indians are really great at mathematics, I am always awed to how fast they could answer any equation even the complex ones.

  10. All our Indian scientist known as Rishi they all know more about future that we are not able even think about it .by the power of yoga,medidation,nature and spirituality along with their great mind

  11. If you all like this than please search about a great mathematician sirman Ramanujan.he is one of greatest human calculator.

  12. Well it won't be long now , that we all accept that Civilization came from India with the original migration of Arya !. This realization should wipe racism off the planet at the same time !!

  13. Indians copied this concepts from Greeks
    Vedas are also translations or by products of Greeks because Greeks nobles and kings Ruled Ancient India.

  14. Thank you very much! Please upload more and more videos. That is the power of Indian sciences. Indian sciences must be preserved and popularised like western education. Indians are themselves ignoring their sciences due to the western education system.

  15. See Russian people are including it in their education system but we Indians are blindly popularising western education in our country destroying our own great education.

  16. A child would need a life time to learn multiplication in Vedic way , with so many different formlae .Is it use ful any way .

  17. There is an another way to find out the squares above 100.
    Put 1 then double the digit then square the digit.
    For eg: 108
    Put 1. then double 8, means 16. Then square 8, means 64.
    So the answer is 11664.

  18. Many words of English has come 4m Sanskrit like heart 4m hrid,dental 4m danta,saint 4m santha, navel 4m navi, navy 4m nav, path 4m path, cent 4m sat, deci 4m das, no 4m na, new 4m nav, I am 4m aham, same 4m sama mother 4m matara, father 4m pitara,brother 4m bhratar, they 4m tau, trigonometry 4m trikonmiti, geometry 4m jyamiti, lakh 4m lakshya, three 4m tri, deity 4m devta, devine 4m divya,serpent 4m sarpa like many more.. Be proud of being a Santana hindu.

  19. Best part about the Vedic maths ? You cannot teach this compulsory in every school why ? Because we are Secular country isn't it so cool to be in Secular Country 😍🥰 We don't teach this method in India because we respect all Religion .
