Yes sir
Absolutely sir
Thank you
Oh we injoyed it. :)))
Where r u from
I needed this guy to be my math tutor , this information is superb.
That's why Most of Indian are math genious
@@abhi_anand7061 Sorry to say this, but I am much faster than this tutor.
I always get high grades in maths because of this man . Big Thanks
I took humanities as major in high school just bcoz im afraid of maths, but later realised, that temporary fear permanently made me nothing...it is the bad methods taught in school which makes everyone hate maths...i should've taken science in highschool...long story short, i fked up

Ok this is genuinely the best advice for mental multiplication that I’ve ever seen. I do something similar naturally so this method just makes sense and has really helped me. Thank you!
glad to hear that !

The best video for mental maths
To be honest, I really don't depend on school for Math anymore, I depend on your videos, because they make me understand better.

Very impressive I can see here the beauty of relationships between numbers. This is full of fast thinking and creativity
I can flex in front of my maths sir now 😂
Same
Also in front of friend
You'll take seconds but I could say 1 to 100 square in just a sec! You can ask any random square between 1-100

You're such a great and patient teacher. Thank you so much for all your hard work and for these videos. As a grown up, I realised I'm pretty awful at Mental Maths. I hated Maths at school. Now I'm brushing up with your help :)
I’m compelled to tell viewers how my son learned the tables after coming home from school. I wrote tables of 1-10.
I told him not to memorize because that would have burdened him but only read it daily.
After a number of days the tables embedded in his mind. Upon asking any 2 digits he would give the correct answer.
I then went from 11 to 20.
At 44 now, he can answer multiplication of any numbers on that table.
The viewers, their kids or grandchildren may benefit and wouldn’t burden or stress themselves. Reading is easier than memorizing. However reading again and again and again automatically gets embedded.
I am not the best in maths but because of you I can see big improvement.... thank you
This basic math calculation techniques that you teach us is really useful for our life. We use + - ×÷ almost everyday. Thanks for sharing your knowledge with us. May your life always blessed.
I played your game and i enjoyed it when i was able to practice what i learned, but lots of times there were new things that i didn't learn yet so it kinda put me down.
I hope that you can develop it, like making sections for each lesson, or category.
Thanks for your amazing videos and for the game.,
You have my respect. 🖤🖤
You are the most relaxing mathmagician I have ever listened to. Have a good day.
:)
I found out that doing it the school taught way was faster on paper, but in your head, this was faster. Plus we are all used to the school way, cause we have been practicing math that way. If I practiced these methods, I would certainly be faster than a person with a calculator or using the school-taught way. Thank you for your great advice on math, I will continue to strive for my goals. Just started these methods a couple of days ago and I feel like I'm slowly becoming faster. Thank you.
I agree with you, i think slowly i will calculate at decent speed atleast
Exactly same feeling
Yeah but doing mental math and paper is faster that the school thaught way.
यह ट्रिक हमको बहुत अच्छा लगा। यह ट्रिक से कितना भी बड़ा संख्या हो उसको आसानी से सॉल्व कर सकते हैं। आपका बहुत-बहुत धन्यवाद हम को इतना अच्छा ट्रिक सिखाने के लिए।
Thank you so much! I want to improve my mental math's and you are the right person to go to! Thank you!
props to this guy. I cannot see a single piece of paper in his room, he's a superhuman

Thank's sir because i dont like math before because my head is hurting when my teachor told but when i watch your videos I love math now because your teaching is basic and effective not wasting time thank 😊😊😊😊
This is such a nice square calculation, I love it !
im watching this at 2:30 in the morning so this is just flying over my head lol. ill probably watch it again tomorrow so my brain can actually process. it looks really cool and like something id understand
I am enjoying your unique way of teaching mental math.
Last crisss cross method i didnt understand😭😭

you got yourself a new subscriber you are so amazing i am heading into highschool and i really need this thank you!
Bro Thank you for making videos in english😊. Your explanations are very easy to understand and are in simple english👌🏻
I am glad , Please share 😁😁
Sure!
Luv u bro for explaining in English ❤️
Thanks so much! You're so good at math, just look at how many trophy's he has.
Okay, the teachers are learning something right here
You are really underrated bruh!!!!
thanks :) my uploading speed is slow thats why
I am a student and this truly helped a lot, i hope he becomes a teacher
There is another easy method for squaring two digit no..... For example let's take 23 so here we need to do square of 2 which will be 4 and then we need to multiply 2 with both the no. So 2×2×3 and then again square of 3 which is 9.....so overall it will be 4 12 9...where the 1 will be added to 4 and the answer will be 529....and I think it's much easier and quicker... thankyou ❤️
very well explained, i am in 7th grade and i take loads of help from your videos, i’m pretty sure i wouldn’t have known many of these methods if not for you, i have subscribed to your channel.
I have another way to do a square of two digit numbers that start with 1.
For example:-
12×12
So first we are going, to just multiply 2 with 12 which is 24, then we are going to plus 24
12×
Which is 144. This doesn't seems the simplest but it is easier for me.
12x13, 2x3=6(unit place)and 12+3=15, so 156 is the answer. If two digit got in unit multiplication, there is a carry over.

1:30 - Squaring numbers
Round and add subtract other number opposite of what you did to round then square that number and add to bigger number you multiplied
3:00 - 2 by 1 Multiplication by addition
Take apart as hundreds, tens, ones and multiply left to right
4:00 - subtraction method of multiply
Take apart as 100 tens ones and multiply each.
Can round up but subtract missing and multiply parts
8:53 - factoring method
11:15 criss cross method
Súuuuuuuuuuper trick. Thank you so much.
Tomorrow is may mental math competition at state level these videos are very helpful
I just discovered you and I already love u! Thank you
Watching this during online classes is really benifited🙌 🤪
Well done keep it up
Bruh indian?
LOVE YOU BROTHER.WHAT AN AMAZING WAY YOU TEACH AND I REALLY ENJOYED IT.I HAVE A PRAY FOR YOU THAT ALLAH GIVE YOU MORE MORE SUCESS IN YOUR LIFE.LOVE AND SUB FOR YOU FROM PAKISTAN
My memorizations 60 years ago are still with me.
I had memorized squares of 2-30 and cubes of 2 to 15.
Some of your and others’ ifeas of multiplication are faster.
e.g. 97 x 93
Best explanation
It is proud to be know that you are an Indian
I think that next Ramanujan will be you
I’ve been a human calculator since I’ve watched u my friends ask me how I do it in. Y head so fast I will never tell them your my secret weapon :)
bro Human mind is infinitely Gifted No words 💓
what a Human mind can do it's unimaginable 💓🔥
Thanks, i learned alot from you, i hope you will get millions of subscribers because your knowledge and explaining is top notch.
There is a faster way of multiplying 2 digit numbers together and that is multiply vertically (like in the criss cross method) but not diagonally. Then after you do that then multiply diagonally and add.
Tommorow is my mental maths compittion.big thanks to this bro for this video.
Just started joining this guy .And it's really helping me thank you so much
If you have your squares memorised then 42*46 is 44²-4, which is 1936-4=1932
Just to show there's so many ways to think through a problem, when I saw 46x42 I saw 44+2 times 44-2 and so I knew it was 44^2 - 2^2. 44 squared is 16x11x11 and there's a nice technique for multiplying by 11 to get to 1936 and then subtract 2^2 to get 1932.
i alway get high grade in math because of him thank you so much
Thanks man! this is helpful
1:35 2:27🔥&& square any 2-digit number
it is helpful for going back to School and for being learning a new way of Learning Basic math
This Man is very good at math really fast
Shakuntala devi pride of India🙏
You already know your gonna learn something new with that accent 👁👄👁✨ this helped me sooo much tysm 🥺🤍🌸✨
So new, so real.
Thanks very much bhaiyaa
I wasn't aware but i was using factoring method for a long time.
I learned this myself doing difficult operations.
Never give Up man I love your videos
I THANK THIS MAN SO MUCH
I like this video, thank you so much!
this is the best from just liking maths to loving maths
You are one of the best thanks for giving us your time
Just understood it . Wow! Thanks , very helpful and engaging maths !
Thank you so much I learned another way but I just couldn’t do it in my head, but I was easily able to do it with your method. Thank you :)
this is really helpful for me cause I'm getting into harder math thanks man!!
your explanation is very good
This is superbb💯
I even can't find it in Vedic math
You are my champion ship of maths
Sir just a suggestion I would love to give right now: while multiphying my 5 we can just half the number and add a zero.
For eg: 42 X 5 = 210 same as half of 42(ie 21) and a zero another one 52 X 5 = 260
damn boi,thats too cool! Thanks
With Unary Numeral we can do like this 41*5 = 205 how to make it simple, half 41 is 20.5, remove the dot it will be 205
another example: 53*5 = 265 half 53 is 26.5 remove the dot it will be 265

This is a good learnin video! Im a 11 yr old in 6th grade improving at math because fo u, keep the good work, 6:17
All I can say i you’re a god.
The last multiplication of 3 digit 857●762 i began it from left to right and done before the hundreds 8●7, then add the *sum* of the the double cross multiplication of 8●6 + 5●7, then I add the SUM of the trouble multiplication of 8●2 + 5●6 + 7●7, then I began to multiplicate another time the double multiplication of 5●2 + 7●6 , and at least I multiplication the UNITS digit of 2●7 and add it .
Sorry. I have given wrong answer in the above comment. Here a new calculation.
857*765 = 6375//1800//105
= 655605
You are truely awesome man.
Big and big hearts
we can use 10 even in 19square by doing
19 10
x19 AS x 28 = 280 + 9square which is 361 ......easy
Yeah but rounding 19 into 20 and down 19 to 18 is much easier to calculate.
I will always follow left to right
Great math skills keep it up 💪💪
It helped me in my exam sir
thanks for sharing your knowledge...
Thanks very easy to understand 😊
glad :)

Thx man. This help me alot!😀
