32:20 - 967458
=9+6+7+4+5+8
=39
=3+9
=12
So,it is divisible by 3 because 12 come's in the table of 3.
13 se bhi ho skta hai 3 into 13 krke =39 aur 12 bhi hai
Wow sir you are super Genesis in maths sir you teaching is very good I like maths class by this sir THANK YOU sir for clearing my all doubt sir ☺
23:02 sir aap sorry kyu bol rahe ho, aapke inhi mazak ke saath to maths padhne mai maza aata hai

Sir we are not playing with numbers
Numbers are playing with us😂😂😂
Thank you so much sir I was crying that maths would not be in my hand butt.... you made maths easy thankyou very much sir ❤ I am obsessed with your teaching style
Thank you sir
But sir A B + 3 7= 6 A in this question we have to put the same value of A but we use different values of A i.e (A=2 and A=1) So, sir how this is right?
Sir mere final exam ho gya math ka or bahut hi accha hua
Playing with the numbers is the first chapter in my book
Sir is of fuesir
Kon kon 2024 me dekh reha hai😅😅😅😅
Abey httt😂

Test of divisibility is 7
Question-: 4832718
Numbering7654321
1,3,5,7 = 8+7+3+4 =22
2,4,6 =1+2+8 = 11
(22-11)= 11 it's means that its is divisible by 11
(I am right sir)
Hmm??
Hellooo..my best maths teacher and friend, you are very amazing and awesome. And sir aapki faltu baatein bahut badhiya lagti hain💛😆😄jabki vo faltu hoti hi nahii👍🏻😍 Nice to see you again in a lecture..😍 Sir if you remember me, the please reply..
32:17 Ans. Yes, 967458 is divisible by 3.
53:59 Ans. No, 1067 isn't divisible by 7.
1:15:42 Ans. (i) A=7, B=9
(ii) A=4, B=7
Sir your teaching style is so soooooo good . I am very great full to have the best teacher in the world❤❤❤
Sir, I understand the chapter but , my book is different and it has different questions so, I didn't understand few questions. the question is , the product of two digit natural no. is 1938 . if the product of their ones digit is 28 and that of their tens digit is 15 , find the no.?
Thank you sir for this session 🙏🏻🙏🏻
Sir you are fantastic you are not toxic like other teachers
Thanks for teaching sirr 😄 I understand everything that you have tell in the chapter thank you very much 😃😆
Now last video of class 8 but not the least as isaw sir is also their in 9th and sir the experience was so speechless with you becasue before exam i watch your videos and then i can score 35+ marks in maths thank sir for providing this much quality education for whole year 👋👋👋👋👋
55:11 examples from mine book (Rs Aggarwal class 8th)
Same book
What a wonderful explanation
32:14 it is divisible by 3 bcz the sum is 39 which is divisible by 3
Your explanation is very helpful for us 😊😊😊😊😊
The way he teach us is awesome🥰🥰😇
Ans of 53:55 (iii) 1067 is divisible by 7 bcz (7*7)=49 and (106-49)= 56 and 56 is divisible by 7.
Thanku sir for this type of teaching you are a great teacher of mine 😊😊
Unfortunately, your answer is wrong because we have to double the last digit and not to find the square of it like you did it here
We have to do this:-
7×2=14, not 7²=7×7=49
According to this 106-14=92,
And 92 does not come in the table of 7!❤
P.S:- I am just correcting you! I have no hate against you
Peace 🙏
But bro I have not find the square I just multiply 7 and 7 so I get 49 and first 3 digit 106 we have to minus 49 from 106 so we get 56 and it is divisible by 7 but you have multiply 7 and 7 you got 49 its correct but you subtracted wrong you subtract 14 from 106 instead of 49 😊
I hope you understand
My all doubt was clear thank you for this lecture sir
Thank you sir it's make better to understanding mathematics thank you sir
Merko 8th mein esa teacher kyun nai mila😂
Pdhane ka style dekh k mein aa gya🙇♂️🍷
Ha yr 🤣✌
Sir ye chapter padh ke maja aa gya Kya baat hai😅🎉
Superb teaching style sir 👌
47:36 aise toh sir 4 ke table me Jo aye wo 2 se divisible hai😁
This is one of the easiest chapter in whole CBSE Bcz of ritik sir
Sir I love ur teachings very much but there is a mistake u made at 12:23 actually it is 10c but u had written 10a. 100a and 10a are like terms😅😅
Sir agar hame kisi decimal number ko generalized karna h ,for example 48.66 to ham usse 4×10 + 8×1 + 6\10 + 6\100 aise likhenge kya? Please tell me, I'm Confused.
Yes, we can write
sir aapke jaisa teacher ho toh koi maths chhodne ke baare mein sochega bhi nhi Thankyou Sir😊
Ya really
Bro i solve a question = which of the following numbers divisible by 2. The question is 93 and i add 9+3 and it came 12 and i add 1+2=3 so which is correct? 12 or 3?
12
The Divisibility Rule for 2 is that the units place should have 0, 2, 4, 6, or 8......93 has 3 in its units place therefore it is not divisible by 2....
Outstanding😍😍😘
Truly a good teacher deserves❤
sir you are the best teacher. You are the best than the ALLEN teachers they also teach good but not more than you 😊😊
I was never interested in maths but because of him now maths is one of my favourite subject thanku sir for teaching us in such a way I hope you will teach us in 9 also once again thanku sir ☺️☺️

Sir I am also teaching maths in nearby school this is my first experience to teach in school so I would definitely be nervous but har naye chapter ko start karne se pehle aapka video dekh leti hu to ab tension nahi hoti kyunki aapka channel hai full support to you sir also thanks ke aap hum jaise teachers ke liye bhi helpful content dalte hai😊
Excuse me sir I want to say that in the topic of replacing the alphabet using a suitable number
In the 2nd question the B's value is 7 not 6 only this is the miner correction and thank you so much 🙏🏻 🎉❤ for clearing all the concepts
1:10:57 We can give the values, B=0, A=5 and C=2 as well, right?
Thanks sir for your guidence only because of you I am able to score full marks in maths after 6th class.

I was not having interest in maths,but when sir came to teach I was very happy to solve maths..Thank you sir for teaching
Very nice 👍👍👍👍👍🙂🙂👍🙂👍🙂🙂👍
आपका yutude चैनल ha na
A legendary teacher....... .
sir thanks for your time and the question 100*a 10*c + b =acb and you are giving most important part which is time and thanks for it
47:06 (ii) It will be divisible by 8 because the last three digits ie 312 is divisible by 8*39=312 it means the number 570312 is divisible by 8 (iii)it will not be divisible by 8 because the last three digits ie 218 does not come in the table of 8 thats why the number 685218 is not divisible by 8
Yes u just forgive him
😅
Thank you sir your explanation is very good 👍 😃 😊
sir , your teaching lecture is so good
Sir mujhe ye question bata de replace the letter in the puzzle. With digit from 1to9 ( with repetition) such that the sum the numbers on each side of triangle is 15
Please
divisibility by 11(H.W)
(ii)4832718= no sir it is not divisible by 11, because after the subtraction of the sum of even & odd numbers (10) the number is not 0 or in the table of 11.
No actually your answer is wrong when we add even number 8+7+3+4=22
odd number 1+2+8=11
so the answer will be=22-11=11

Sir ur teaching is superb😍😍😍
divisibility by 7 (H.W)
(iii)1067= no sir it is not divisible by 7. because after subtracting the double of 7 (unit's place) from the remaining number (106)
the number (92) is not divisible by 7.
