Sir, 7th question - 112 - 11 = 101 , then carry 2 so left side would be 99 and right right 200- 132 = 68 . So Ans= 9968 ......
Yes..

Yes ... around ~14:00
if you know, you know!

We are not learning it for the sake of happiness. How far a statement and the truth inside it 😂😂😂 you nailed it sir
112-11=101 sir 7th question
Exactly
Sir ji merko to apne pe shak ho gaya tha

Sir at 15:50 7th question : 112 - 11 = 101 , then carry 2 so left side would be 99 and right right 200- 132 = 68 . So Ans= 9968
please check this.
yes
sir in 7th question there is a slight mistake it will not be 111 it will be 101 and subtracting 2 it will be 99 so the answer would be 9968
Thank you so much sir for explaining these topics so easily its is very helpful for us
in this problem we can follow previous rule by subtracting 101-1=100, right side -32. Now, Rhs 100-32=68, Lhs 100-1=99. Final Answer is 9968
@@CodeNectar620 Ye logic sab me nhi chalega viru
yes its 9968
It's is 9968
I really appreciate sir for posting whole material of Quants on UA-cam for free. Also, the guys who are pointing out mistakes in the videos, I think you should correct it, as these are very small mistakes and can happen with anyone.
Again Thank You Sir for providing these videos for free.
Where r materials ??
@@MBA_DREAMER you are noob bro if you don't understand normal logical things then god is your savior
112*89=9968 please correct it
yes
Sir, gave us lesson that no matter calculation is done but we should always calculate by our own.☺
Sir's sarcastic expression at 4:45 while saying" we aren't learning it for the sake of happiness… " made me laugh twice 😂

Are these all the videos related to the quant chapters? The way you concluded the fourth and final lecture of 'speed math' suggested that there might be more videos following it. It appears that they have not been uploaded to this channel. I felt the same while doing time and work. Please clarify, sir.
Sir in ex no 7
112*89=9968 not 10968 plz correct it
I Appreciate the way you are teaching, it doesn't feel like i am learning from a yt video.
Really appreciate your teaching sir 👍🏼
Thankyou so much
daily dose of appreciating you sir❣
I have get to know this channel at 3May 2024
Now at 5 May i did 2 classes. My mind blown withoit using pen...

To eliminate sign carry 1 from left to right in case of minus sign
Speed maths lectures getting completed with great speed
sir 7th question 112-11= 101 and 89+12 =101 and then carry 2 base from 200 would be 99 and 200-132=68thn ans will be 9968
Yes.
I Just wanna say that sir you are perfect💯👍 keep going
May God bless you
we can also do this 116 * 87 we will get that number 103 and - 208 just take 10 from 103 it will be 1000 - 208 its 792 116-10 is 102 remaining is 792 so the answer is 102792
i think this one is easy
Sir, you are wrong at 15.54 minutes.
Your question was 112×89 =10968 but the right answer is 9968.
Genuinely highly informative session😊
sir,112 multiply by 89 is incorrect at 16:12 minutes u can have a look
Hey....I have created a wp group for cat aspirants... if you would like to be added text me on wp...my number is given in about section of my channel
According to this method, how should i multiply 45*65 ?
Sir... It's really very helpful

The way you have been giving us all the CAT related content & that too free of cost is just truly commendable. We will be forever grateful for your hard work sir. May God fulfill all your wishes 🙏
QUESTION 11 , ANSWER IS 9968.
Now we are faster than calculator 😁
For no's only close to 10^n,😂😂
@@Abhishek-ye9kq
Awesome explanation sir, hats off to you
❤️🖤
112*89 I think he's checking our attention!!
thank you sir for your nice explanation of all the topics till now and especially prime no ,AWESOME
theiris calculation error in question 112 * 89 is 9968
Sir your way of explanation is too good ❤ ty but when you explain sometimes you write 109 on behalf of 99 , 112 on behalf of 102 so see that things otherwise you're too good sir love you. Just a feedback ❤
Itna accha to school mein bhi nhi padha tha🥰
You are the best teacher
Sir u made me feel that math is too much comfortable while following ur tricks to solve problems
Salute to u sir🫡🙌🙌🙂. Enjoying ur all sessions sir
Had a doubt that can this method of multiplication be used in case we have a sum like
3789*78, here there is a difference in bases for both the number
The above number is closer to 10^3 while lower number is closer to 10^2
HOW TO DO SUMS IN THIS CASE?
have this same doubt
The session was really great sir!! thankyou
Day 3
bruh this is magic....
Can we use the multiplication shortcut for all the cases? Or just for the numbers close to various 10 bases?
Amazing concept 👌 ✨️
What if there is 200 in question. let's take e.g 207 multiply 211 what's method we can use here. can anybody tell me?
Yes
@@Rodha Thank's sir🤟 I didn't see the next video that's tell about this method.
in the question 112*89 , you have subtracted wrong (112- 11 is 101 and not 111), that multiplication answer is wrong, please re check
Is there any approach when numbers are far from 10 base?
For numbers like -
57 × 89
49 × 55
did uh get the answer from somewhere else
okayy, so i got a solution in the comments section itself.....
Okay friends, here new trick for 2 digit number, product.
42×32=
So first 4*3=12 and
2*2=4.
So 1204.
Then cross multiplication.
(3*2 )+(4*2) =14.
1204
+ 140
----------
1344.
I know it seems lengthy, but trust me , it's easy for mental calculation
@@ankitagarwal4206 seems easy, thank you!
Sir checking us we do r not 😅
Some problems 😂
In question:
112 × 89 = 9968 ( not 10968 )
; 112 - 11 = 101 ( not 111 )
Same for 89+12 ( 101 )
So, 101-2 = 98 ( not 109 )
I got confused while solving but it turned out to be calculation mistake from you sir.
And what you are doing is just commendable sir !!
We do need teachers like you
from the 14 min 45 sec 112*89 YOU HAVE DID WRONG sir !
Thankyou so much sir ❤️ you are great !!🙏
Thank you sir all the technique where helpfull 🙏🏼
Dear Sir,
The video was really amazing and I got to learn something new. But, at around 16:00 the answer is coming around 112*89=9968 against 10968.
Many videos I recorded between 3 am to 5 am, as that was only time left for me after work and study. So Lil calculation mistakes are there. But you won't find any conceptual mistakes :)
@@Rodha Love your Content Sir

Why did you take 140 instead of 14 here?
Why 1204 instead of 124 and 140 instead of 14... anyone know please answer
this is actually good and also its not lengthy at all with practice one can solve it in 10-15 sec
@@ankitagarwal4206 indeed It is
@@asthasingh48you have to use 0 cuz even when we multiply by usual way last digit has × means it's as it is
10:36 the base is 100 then why didnt you took 12x7 as 084? Because in previous sums We assign places based on bases. Please clarify
*Thank you so much sir for this beautiful trick*
Lovable classes sir thank you very much
Sir sorry to say but in your one question no. 7 is have little mistake.
112-11= 101
If we take 2 from 101 to substrat the 132 then is will be
99|200-132
9968
Sir 112 × 89 = 9968 , you missed it in the cross addition part.
Sir if we having 48x52 ,so what we take (100 - or 10+)
Answer of 7th 9968
Kya baat h sir
Hey bro...I have created a wp group for cat aspirants if you would like to be added text me on wp...my number ig given in about section of my channel
112×89 it's 9968 please correct it sir
sir question 112*89 answer is wrong because 112+(-11)=101 not 111
Amazing concept but the sums and calculation are bit incorrect. I have been following you for my further studies and it's been thrice the calculation are mistake.
Where can I get the remaining video, like the problems of Other bases? Is any video available?
the sound quality is very poor when i use earbuds
Both r 🤔correct but how we
at 14.50 , 112 minus 11 becomes 101 and not 111. Final answer becomes 9968
Sir What if both the numbers are not nearer to the same 10 power x value?? Then how to solve??
Same question
SIR, you have made a mistake ( 112*89 = 9968 not 10968 )
112*89 =9968 correct it sir , there is something wrong
14:54 112-11 is 101 and the final answer is 9968
14:52 sir human error(Calculation error!)!!
Hahahaha humman error 😂
112×89= 9968 sir your answer is wrong your answer came 10968 which is wrong
can you please send me method for base 600 that is 529*734?
I think I can do normal multiplication faster :D
lol
😂😂🤣
Those who focusing on mistakes plz focus on concepttt
Sir please solve the problem (114*86=9804) how it comes by using this tricks?
sir in this video 112*89 ans calculation is wrong it is 9968
in 112 & 89 numerical answer is 9968 as cross addition comes as 101 & not 111. Correct me, if I am wrong
Yeah. That's calculation issue
sir your eighth ques which is 112 multiply by 89 is wrong
Sir, they will provide digital calculator?
I had this doubt , that how will we know that 0 is to be added before any digit or after…..(reference 5:36 )
please solve 12*13 with the same method I think this is getting failed. I might be wrong but as per my analysis, it's getting failed.
5:52 multiplication close to 10 power
Superb calculations
Superb way
the last digits should not be more than the power of 10?
FAAD DIYE GURU JI PURA SAMJHA ☺🥰🥰😇
everyone focused on just silly mistake instead of focusing his whole strategy 👍👍
Sir, a different case is there that is114×86.
Everything is good but a little bit correction needed 112-11 is 101 ..
Love you, sir. Zindabad, Lajawab Jai Hind, Jai Bharat.
sir, 112*89 ans was wrong, u hve written 10968...... but ans is 9968
sir 7th qusestion 112-11 =101

116*122 sir could you share of this answer with this formula
