[@DavidKChen-ys4tt]

Great video! The method used to solve the problem was really effective and easy-to-learn. I really appreciate the effective use of colours when explaining the problem.

At around 7:09, I didn't understand why in A U B' you included 6 and 7... B = {2,4,5,6,7} B' = {9,10,17,19,20,21} The way I see it is instead of painting the circles in color,you could just paint B in one color and say that A U B' is everything outside of the colored circle B. Am I not getting something ? Like your videos,BTW,very helpful. ================================= Edit*** NVM Got it. A = {6,7,9,10,17,19} B' = {9,10,17,19,20,21} Then Obviously A U B' = {6,7,9,10,17,19,20,21}. :)

[@Mathispower4u]

Because it is the Union of the two sets, which means in A OR in B'. 6 and 7 are in A so 6 and 7 are in A OR B'.

For the FIRST time in my life I did a better drawing than the teacher. Still got one number out of place, but my drawing was good.

[@ianhruday9584]

Shouldn't there be brackets?

[@christianangus4753]

I have a question U={1,2,3,4,5,6} A={1,3,5} B={2,4,5,6} C={1,2,4,6} D={2,4} Whats A Union B with U?

[@annstrashfoe]

very helpful!!

[@TheAmeliix]

can you be my math teacher?

[@appealingtodasenses]

why doesn't number 4 include 20 and 21 as well

[@luisdfernandez2601]

I believe because 20 and 21 do not intersect B. It's like U intersecting B provides 2, 4, and 5.

[@opaapo1]
