Guys, don't do that for every number, it is only for specific numbers. Look, for example, 82 x 47, when you do his way, it is 1614, but if you do it in the standard algorithm or FOIL or any other way, it is 3854(I even used a calculator). I am not trying to be mean but that way is only for specific numbers and not for all numbers, I suggest you should do FOIL on most 2-digit numbers multiplied by 2- digit numbers. Again, I am just suggesting it and I'm trying to not be mean or anything. And also for the 3-digit numbers multiplied by the 3-digit numbers, you should also use extended- FOIL.
Oh, another _magic_ math method that seems to work only for certain clunky conditions! =D Here's what happens in the video. 56x54 can be represented as (5*10+6)(5*10+4), or (10a+b)(10c+d). According to the video, the result would be equal to 100*5(5+1)+6*4 or 100a(a+1)+b*d, if we were to express it in an abstract form. As described in the video, this method only works when the first digits of the numbers are the same (a=c) and second digits accumulate to 10 (b+d=10). So, let's apply this to our equation: {c=a; d=10-b} (10a+b)(10a+10-b). When we remove the brackets, we get this: 100a^2 + 100a - 10ab + 10ba + 10b - b^2. 10ba cancels out the -10ab, and we are left with 100a^2 + 100a + 10b - b^2. "But wait", you might say, "tis doeth not look like the original result at all! Thy math is thus flawed and our _magic_ math prevails!". Sure, it does look a wee different, but what if we were to factorise some of these mononomials, we start getting there: 100a(a+1)+b(10-b). But this is still not the same as the initial supposed result, right? Wrong! Remember there was a condition that this will only work when a=c and b+d=10? Well, what do we have in the last pair of brackets? 10-b. Which is exactly the d we were looking for. So finally, we get the same result as our friend demonstrated: 100a(a+1)+b*d.
The problem with all these various short cut methods.. by the time you go through them all in your head trying to remember if any apply when doing day to day maths. If you even remember which possible techniques can be used. You've wasted more time than if you worked them out normally to begin with.
this formula doesn't work for every number bro. it has a restriction that first no should be same and the last two no. should sum out to be 10. plz make things clear.
So helpful!!!! Let me explain in short In multiplication if THREE of these conditions is satisfied, one can use THIS method 1. The number of digits should be same on both sides of the multiplication 2.the last digits of both numbers to be multiplied should sum up to 10 3. The numbers on the left of these two numbers which adds 10 must be same That's it
lets say you chose 2 numbers, xy X zw to apply this process there are 2 conditions must be satisfied, 1. x must be equal to z 2. y+w must be equal to 10 if you apply these 2 conditions you can use this process, otherwise it doesnt work
He said that this trick only works when like the first digit of the number is the same as the other number’s first digit. Plus, he also said that the last digits of the numbers you are multiplying has to equal to 10. So, don’t use this trick unless these things are in the numbers! ♥️
my gawd i was all for it, until he mentioned the two conditions... like, then it would take more than 3 secs cuz u have to make sure the problem satisfies the two conditions b4 u move on. and in that time i can just use my calc anyways.
Your trick's good but way to many conditions!! It will be useful only once in a while!! Give us something more open and more usable!! Hope to see another good video
you must to have two conditions for use this method! first... the first number on both are there the same... second condition is the second numbers must get 10 for example 72+78 the first numer are the same 7 and the second numbers 2+8 =10 the conditions are good for the method
This method only work for last digit that sum up to 10 like 4+6=10 (e.g 43*57 in this case 3+7 equal 10 so this method only work for this kind of number) i highly recommend you do the maths in a traditional way
You are fooling the people by telling that this method is easy when it is only applicable for a few examples. Vedic Maths is so dam easy and effective. And it works for all examples.
He said, the first two numbers have to be the same; and, the last two should add up to 10. In the case of 16 x 17. The first two digits are the same: 1/but, the 2nd two digits 6+7 do NOT add up to 10. That explains why it didn't work!
guys watch the whole video before commenting "29 x 32 won't work!!!11" he literally explains the two conditions that need to be satisfied for the trick to work the tens place in both digits must be equal and the one's place plus the one's place must equal 10
Ya....but the 2nd unit places of there sum is not equals to 10...as..according to ur sum 7+5 is 12 .....not 10...so that...this above condision was....incorrect for ur sum...once look at the above sum ....clearly...it mentioned
+Gundlapalli lokesh Like he said in order for this method to work there must be two conditions 1st) first numbers or integers should be the same 2nd) the last should be a sum=10, so for your example 24x25 ... The 1st condition is met but the second is not met since 4+5=9 and not=10 ... I hope that helps

Hi there, the tricks are not too difficult and probably well known to guys who like to play with mental math tricks. You are welcome to check out some of the short videos I posted a couple of days ago for a few fun math tricks too. :)
Bcz they already mention tht 2 conditions must be satisfy,, 1)starting digit must be same, 2) unit digit addition must be 10.. that time only you apply this trick.. Ty.

Wow, you've found a way to quickly multiply 2 numbers that have the same first digits and where the second digits add up to ten. That is so useful.... NOT.
+Andrea Tran it is completely useless, you'll rarely find two numbers to multiply that have the same first digits and remaining digits that add up to ten when you're in the real world
Extremely rubbish. I bet from100 percent there is a 0.001% chance of satisfaction of these 2 conditions..... Not impressed . Yeh india saara kachra hi bolta hay
The problem that I have I haven't seen your previous videos. Please, can you place a link to all relevant videos? 12x11 had to use 6x11 then doubled to verify 132 is correct. I am just playing your video again and to multiply by 11 N+1 and add the 2 digits together and place between the N+1's 2 digits. I wish that we learnt these easy tricks at school in England, UK.
you need two conditions... the first number are the same in both and the second condition is the second number they must to get 10 for example... 72+78 the first number in both is 7 and the seconds numbers 2+8 are 10... this two conditions must there are.
Way too many conditions need to be met in order for this to be practical.
Guys, don't do that for every number, it is only for specific numbers.

Found this video in my YT recommendations 14 years later
It is very good video
Good exercise for brain
It will help many students
Those two conditions make this trick worthless. You have to know ways that ALWAYS work; otherwise, you'll end up getting confused and making mistakes.
Thanks for this! Really enjoyed this video sir!

Let me explain in short
In multiplication if THREE of these conditions is satisfied, one can use THIS method
1. The number of digits should be same on both sides of the multiplication
2.the last digits of both numbers to be multiplied should sum up to 10
3. The numbers on the left of these two numbers which adds 10 must be same
That's it
only some number can be done as this formula.
Thank you for explaining the conditions hahahhahahaha it was too good to be easy.
lets say you chose 2 numbers, xy X zw

1. x must be equal to z
2. y+w must be equal to 10

For those that still don't understand, both ones digits have to add up to 10 to satisfy this method
do not abuse a great person like him....may god bless you
Please this trick remains in the black box. The more relevant question is the why.

Me:For you!😂
It is true math is easy!
This trick they didn't teach me at school 😂.. Like a boss
But it is not for all numbers
Eg: 43×21

Yah tss tss
the first 2 no. should be equal lmao

"29 x 32 won't work!!!11"
he literally explains the two conditions that need to be satisfied for the trick to work
the tens place in both digits must be equal
and the one's place plus the one's place must equal 10
multiplication of 33 and 79 pls do it bro in this way and then prove ur method is correct
This formula doesn't work then
Sum of unit digit must be equal to 10
There are 2 conditions which have to be satisfied
He has already given two limitations...
conditions are hard to locate which ends up in the long ass way
Yep math is soooo easy...
1 + 1 = 3
This method works only for 1-9, 2-8,3-7,4-6,5-5. It does not work for every number.
Sir but by doing this it giving me incorrect even I use those conditions that you talk in this video
67×65=4235 by doing ur method but answer is 4355

is met but the second is not met since 4+5=9 and not=10 ... I hope that

Not to be offensive or anything but your accent is really annoying lol
you need two conditions... the first number are the same in both and the second condition is the second number they must to get 10
for example... 72+78 the first number in both is 7 and the seconds numbers 2+8 are 10... this two conditions must there are.
