OK for this video please do multiply numbers with base 100 and with huge gape as of between 49 and 94,I found it slightly different

[@ardoqalib7817]

Thank you so much you are amazing 👍👍👍👍

[@KeerthanaRsRs]

Mam can u calculate 52*92

[@sunitarsingh8132]

Ok

[@naiduch1923]

It's amazing 🙏😊👌👍

[@andrefmartin]

it is specially practical when the numbers are close to their base reference. If the rule is valid, it should be applicable to any pairs of numbers (I guess both under the SAME base, although this premise was not said). So I tried it to calculate, for instance, 54 x 72. It does work, but it requires an additional step: the exceeding part of the left product part over the numbers of zeros of the base, must be added to the rigth sum part to result into the right answer!

[@StarrySkies]

72 -28 54 -46 __________ 26 | 1288 +12 | 88(moving 12 to the other side) 38 | 88 __________ =3888 __________ ur right :D though it would be more practical to multiply normally, this would work well for numbers closer to the base

[@tonybarfridge4369]

You could use base 50, then 50^2= 2500, devs 4x22=88, 25/88+ (22+4)/2=13, 25+13=38, ans=3888. The sum of the deviations is divided by 2 because 50 is half of 100. Or 72x54=72x50=3600, +4x72 (288). Alternately 63^2-9^2 -- the median is 63, deviation 9. 63^2= (60^2+6x3x2x10+3^2)=3600+360+9=3969; -9^2 (81)=3888. Also 72x54=70x50+4x72+2x54-2x4

[@ikramulhaq7883]

norilyn camingawan Don't follow the methods which can't be applied generally.....and used for all..... Always follow standard methods. I think the beauty of any mathematical method lies in its generalization.....

[@mythilipammi5741]

We should go through all the methods suggested that I in,VEDIC maths.the easiest has to be selected according to the problem..in this case 100 may be taken for the base &later the right hand part is raised by siix times.

what the hell try multiplying 29x27 it gives wrong answer

[@maheshwaribootharaju2465]

I tried it after u said...and...it works! Just take the nearest number as 10...and do the same method as shown in the vedio , you'll get 19,17 by subtracting 10 from 29,27 respectively....add 19 and 27 AND multiply 19,17 .....now just add them to the value of the base.....

[@maheshwaribootharaju2465]

Hey friends, I have just uploaded a video of using math formula to make a beating heart graph, check it out, its awesome. (: (:

[@gokulsharma9902]

Hi I converted all the steps of the video in an equation i.e. a×b=(a+(b-B))B+((a-B)(b-B)) in this *a* and b are 2 no. to be multiplied and *B* is the base But there are some rulers for this mutliplication trick that are:- 1) if both no. are positive or negative then take positive base 2)if one is of them is negative then take negative base.... *IMPORTANT* for finding base: 456×631 *First of all remove the ones and tens digits then we will left with 400 and 600. *Now see what is the difference these two no. i.e. 600-400=200 *Now divide difference i.e. 200 into 2 equal parts which are 100 and 100 *Now either add 100 to smallest no. or subtract 100 from largest no and the answer will be your base i.e. 400+100= 500 or 600-100=500 So, 500 is the base. Now,lets multiply 456×631 base= 500 Now, =(a+(b-B))B+((a-B)(b-B)) =(456+(631-500))500+((456-500)(631-500)) =(456+131)500+(-44×131) =587×500+(-5764) =293500-5764 =287736 456×631=287736 Thank you if you like this comment plz give a like 👇👇

This fails for 17*59., unless you carry the digit from the product to the sum in the right place. Not hard to figure out, but this method should be generalized. Also, what happens when different bases? I prefer decomposing numbers into sums by place, the multiplying each set and adding the products.
