Best explained of the topic. Keep moving. Love from Nagpur 👍✌

really good playlists. please keep it going ma'am

Tampering even a small logic can have great impact when one is solving any problem.It is just leads to more confusion

If d/m*n and gcd(m, n) =1 then d must divide m or n and lets say d= d1*d2 and gcd(d1, d2) = 1 then how is it true that d1 divides m and d2 divides n ?

It looks like there is an IFF here? I mean f is multiplicative and F is multiplicative? if yes, it's better to say it in the Part-2 video that tells people we are going to prove the IFF and we will introduce the mobius function, inversion formula, sum of mobius function to help prove the IFF, so the last three videos are more structured.

In this mobius inversion function last step, summation of d/n f(c) = f(n) how that step came?

I don't know what gets into Bing on weekend, first makes an assumption and that is completely baseless and then make me to make that assumption true The only thing he thinks that I will be happy on weekend so I need to irritate him to make him neutral The. I become irritated and make his assumption true and finally what did we achieve?
"I was happy and might work to I was irritated and did not work"

Very helpful thanku so much ma'am

Mam please explain arithmetic all thoeram??

[minhazulislam]

c|(n/d)=d'
c|d'=d & d|n
c|n
i can't understand last 2 lines.. please help me

Isn’t it weird that what she teaches is exactly same as David m Burton..it’s like writing the text…wtf
