[@deanarond5264]

I learned about the casting out of nines about 2 years ago. It is extremely useful!!

[@bhavanaaggarwal7118]

Awesome....keep up the good work :-)

[@cesarlara3579]

How to multiple the decimals

[@srkperera1445]

The way your teaching this maths tricks wonderful.thanks for that.you may have more strength to do more.if you can change letter sizes bit large then its worth.thank u sir

[@pedrobluis]

Please note that a positive result does not guarantee an accurate calculation, in the other hand, a negative result does guarantee an inaccurate calculation. ;)

Hi sir, can we solve simplification questions in bank exams like this?is it a safe way to mark options using this technique.?if yes plz conduct a session on this. It will help a lot

[@sandeshchahar3518]

[@vaibhavreddy2024]

Osm sir u are making intrest towards maths

[@gyanendrakumar2344]

You are genius sir🥇👍👌🙏🙏🙏

[@r.k.luthra370]

what if a student, by mistake, just replaces the 2 digits ( for instance,tens and the units digit ) of the final answer. He or she will get correct single number but, what about the accuracy?

[@rupalisingla8103]

suppose we multiply 568×086 and by mistakes result comes out to be 50000 then also accuracy methods works,then in that case what will be the solution??

[@prabuuthandi4755]

Super sir

[@akanksharastogi3584]

very nic trick

[@badrinath546]

Sir it seems like this method doesn't work always. If we take your example 12345 + 32157 + 21548 = 66050, this method works. But if a student performs this sum and accidentally instead of 66050, what if he gets 65060? Here the sum might be 8, but the answer is wrong. What do we do sir?

[@kajaljain4471]

effective way

[@anbuarasu3307]

Very nice

[@sauravathparia5916]

180%of25501+50%of28999 180/100*25501+50/100*28999 applying ur rule 0(9)/1*4+5/1*1 0+5=5 real ans 60401 i.e 2 not matching kindly help.

[@sauravathparia5916]

the exact real ans is 60401.30close to 60401 i.e 2

[@sureshaggarwal]

+saurav athparia ....only accuracy of simple addition and multiplication can be checked

[@sauravathparia5916]

okay sir . one request plz provide a short cut on simplification/approximation sums asked in banking exams. thank you.

[@time9496]

What are you doing?

[@sauravathparia5916]

how to make 12.75 as a single num or how addition of 230+12.75=242.75 can be checked!?

[@sureshaggarwal]

+saurav athparia ...not for decimals

[@sauravathparia5916]

ok sir

[@sandeshchahar3518]

sir galti se brsin likha gaya mai brain khna chahti hoon

[@badrinath546]

This is called Casting of 9 in Vedic Mathematics

[@atoztech455]

Please upload videos of theroms of ncert book class 9

[@rasikawani9066]

This is not correct method to check right answer bcz single digit could be there for so many wrong numbers. I think it's only for checking wrong answers bcz no guarantee for correct answer.

[@jhonsonjones6340]

Ur awesome sir 😇😇😇

[@leelavatishah8202]
