Thank you so much Professor Brehm. I’m teaching myself programming and I usually hate math but your lessons are so clear and easy to understand that I’m genuinely interested in learning. You are the best!

Your definition of a complement was extremely helpful. I was scratching my head at my textbook explanation and your wording made so much more sense. Thank you for your videos!

[sully]

thank you so much for these videos, we appreciate your hard work

commenting this on every video so u get more reach because these are really helpful and it means way too much to me.

hello professor, i would like to know if operation on sets could be applied on more than 2 sets? Cause all the examples you showed only had 2 sets, such as AuBuC

[jasperling]

For Complement of A intersect B, could I write = {universe | a not in A and x not in B}, since you didn't use the variable u, universe of all 26 letters in the alphabet?

[rushshaw]

Would the set of {D} be the same as {d}? I was wondering this because of the last example you showed where it was spelled as Discrete Math but when declared as a set, it was a lowercase d.

Yo Prof Kimberly, what drawing software do you use?

[dhanvipatel]

for the complement part can notA U B be written as (A U B) ^c ?

[shu-yalin]

A U B = A + B - Int(A, B). A = {1, 4, 7}, B = {4, 5, 6}. If I let A U B = A + B = {1, , 4, 7, 4, 5, 6}. It is still equal to A + B - Int(A, B) = {1, 4, 5, 6, 7}. Is it true?

my professor is not very good in explaining discrete

u are wonderful omg saving my freaking ass !
