Multiplication trick using estimation

[@nuckleman81]

The way I handle smaller ones (single digit in one place) is to just multiply each section and add. For example, 7 x 48 I do 7 x 40 (280) and add 7 x 8 (56), equaling 336.

I LOVE YOUR LESSONS! U R GREATEST MATH TEACHER IN THE WORLD!!!!

[@LudwigSpiegel]

Thank you! Very, very interesting method. Great tutorial.

[@sebastiankumlin9542]

Great fun, and easy!

[@signedup2462]

Neat. Doing that on paper is easy. Taking it mental is work

[@1AndonlyRich]

Nice thanks! You gave me a new way to do multiplication

[@madhabchandramandal5094]

This is very important video

[@jerubaal3333]

WONDERFUL! thank you very very much

[@musicappreciate]

If you do 105x612, you can get 100x612 for 61200, then add 5x612 for 3060. Then add.

[@casuniba9338]

Very interesting....thank you very much

[@cloremancey2653]

This is brilliant

[@Meg99993]

Thank you for the nice tricks. Also on the other videos. But (in my view) the last one would be much quicker to do: 100x612=61200 + 5x612 = 3060 So 61200+3060= 64260 And again only this last one:-)

[@signedup2462]

Nice. You have to recognize the pattern and then you apply the shortcut you know. I do see the 306 being half of 612. Thx

[@manuelmt1681]

It's more complicated.I prefer regular by for eg 8*38 30*8-244,and 8*8-64 and add 244+64- 308

[@rams9574]

30*8 is 240. Not 244.

[@powerofroses1670]

Thank you very much. You are such an inspirational teacher. xD

[@4SevenSeas]

Do you also teach log base 10 calculation and square roots?

[@alak3073]

Thank you. Nice method. I really wonder how it was found ?

Gday and welcome to tech math channel

[@chantalhenderson6994]

I love all your tricks but I actually worked the 7 x 48 in my head much quicker then this system. 7x 50 - 7x2

[@chantalhenderson6994]

but I cant leave you a negative I love your maths.

[@edwarddelgado9654]

I would have done it like 7 x 40 + 7 x 8. But I like the approximation and base methods. You can have fun with doing 3 x 4. And then applying that to 3 digit numbers is awesome. The guy seems cool and he's funny.

[@ziaulhasan6720]

thanks

[@thecalendargod6065]

I love it!

[@QuinsonHonQBB123XX]

Why does it work?

[@seemapatilJapan]

Fun ... Thanks

How to multiply 32 x 68 in this Estimation method?

[@raaj966]

With practice can I master the mental calculation

how to solve 972x872

[@rahmaabbadi599]

Please I want how to i can calculate for Ucmas method please

[@DominoMan571]

I gave you like for interesting method not for short method

[@papalosvlog9587]

Try using this 18×11=198×7=1386

[@sukhjinder71]

I cross multiply everything up to four digits×four digits. It takes me less than 1 minute.

[@dahiruahmed667]

This technique is very interesting. The only problem is the tutor as he is almost speaking to himself.... I m advising to increase the volume please

[@manuelmt1681]

It was 240

[@Jhaaninc]

This is *Vedic mathematics invented in Bharath* (india) 10000 years ago. The brutish tried to bury it but u can't bury the truth now can u!? Bharath is now reclaiming the top spot in the world. Bharat mata ki jai vande mataram 🚩🕉️🚩🙏🏻💪🇮🇳💪🇮🇳💪

[@marioluigi9599]

The British also made you speak English. Time to stop that now

[@Jhaaninc]

@@marioluigi9599 It takes time the brutish had forced us for around 70-80 years to destroy local languages, shame our traditions, manipulate us physically and physiologically. But things are changing slowly. The brutish pm in fact praised our PM. Don't worry slowly it will be done! We have already overtaken the brutish economy and their monopoly over their national game and language! So it's all just a matter of a few more years! 🔱🕉️🥚🙏🏻💪🇮🇳💪🇮🇳💪

[@marioluigi9599]

@@Jhaaninc destroy what? There's way too many languages and traditions in India. You don't need any more of that. What you is less of that, and a lot more cleanliness and maintenance of things, so that not everything decays and falls apart. How to live like this, in a dirty smelly way? I don't understand. It's very strange to me

[@marioluigi9599]

@@Jhaaninc In fact, it's kind of sad that you think "the British PM praised our PM" to be something so great. Who cares about the British pm? Why is he important? This is not the 1800s. He's not controlling the india and the empire And I don't think you've overtaken anybody at football or at the language. That doesn't even make any sense loooool.

[@marioluigi9599]

@@Jhaaninc About India's economy, it's actually a really bad economy for the size of a country that will soon have the biggest population in the world. It's economy should be on the level of China at least, but it's nowhere near that. Many people in India are starving and begging every day on the street. That's not a modern economy at all. It's just the income of a massive population all added up together. That's all it is. It seems a lot because there's so many people. I don't think even you realise the size of the population... but per person, it is a really bad economy. Who wants to live in a place like that?
