I can't express how thankfull I am for this channel! I was convinced I was going to fail discrete math, but thanks to your videos I can actually understand and apply

Thank you.. I have been searching for discrete math videos, and yours are simple to understand! I appreciate your effort!

Once again, thank your for your lesson! Not only you are a great teacher, you are a great humanitarian as well (because you paint the background black ).

Hi, I have a question regarding the example on division rule.
In this case, are you just considering the fact that the arrangement can happen only clockwise and not anticlockwise ? Why did you not multiply the divisor by 2 to handle both cases ? Thank you

[cypriankumiamponsah]

Great content. It has helped me a lot. Thanks so much

[weaponkid]

ok I'm following up to the point where you use the 6 to divide... You found 6 orders that are technically the same arrangement, sure, makes sense, but why do you then divide by 6? Shouldn't you subtract by 6? Obviously you divide because it's an example for the division rule, but I don't understand why you divide other than that
