The visuals are a HUGE help, thank you for uploading this!! This is such a simple concept but for some reason my brain was melting trying to decipher it just from words on a slide.

[ryaneldritch]

Thank you so much! This is probably the 5th video I've seen on the subject and by far the one the helped me the most!

[bone]

this is the best video on this topic. started from the ground and progressively get harder, thank you for the help!

I think the question about the divisibility seems to be 7 or 11 instead of 7 and 11.

[sukruthganesh]

In the problem at 5:00 shouldn't the answer be floor(1000/77) since the question asks the number of positive integers divisible by 7 AND 11 and not 7 OR 11?

[sercan]

for example 10:55, for B and C situations, we cant start with 0 because it would be 9 digits. So this solutions are wrong i think. Am ı wrong?

[techwithtechyYuvi]

Ma'am you didn't mention whether the digits have repetition or not?
