      @@sauravsingh7271 but still for vedic math to work fast for higher numbers needs u to know other numbers square and addition to top that. I mean just look at his speed. And I doubt that if u learnt vedic maths they must have thought the derivation to u.

      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.

      @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.

    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.

    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.

    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.

    You can save time by memorizing all the squares from 10 to 100 to begin with. Since you already know how to square numbers ending in 0 and 5, there are only 70 left to memorize. So it is not that impossible if you think about it. In less than a week you should have it done.
    To calculate addition faster you can visualize that you read the numbers from a whiteboard, you see the numbers there, just like when you see them written with your eyes open. I think that's why he closes his eyes while doing the addition in his mind.
    But you also need to learn how to do subtraction quickly in your mind, for the first step when you go down. 71 to 100 -> you see easily that it is 29, but the other way: 71 - 29 is not that fast unless you have learnt how to do that quickly in your mind.
    And the arm and body movements help him increase the brain's speed to jump to the next step and the next step and so on. Our human brain likes to take pauses, but you must force it to continue with the calculations, step by step, there is no need to freeze the thought on a specific result when you have more steps to do. I think this is the hardest part to master.

    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.

      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.

    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..

    • @joppadoni
      @joppadoni 6 років тому +1

      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

    • @whereswaldo1376
      @whereswaldo1376 5 років тому

      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.

    • @That_One_Guy...
      @That_One_Guy... 5 років тому +7

      easy , you just need to scatter those number into the nearest easy number :
      24 = 20 + 4 , 39 = 40 - 1
      thus 24 x 39 = (20+4)(40-1)

    • @elviopapa5251
      @elviopapa5251 5 років тому +1

      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
