    Re: AUB=

    It mean "A union B" or "A or B"

    What would "A or B" mean with regards to the two sets?.

    It would mean the elements that are in A or B.

    What is in A or B?.


    Now, if the symbol were upside down and you had [tex]A\cap B[/tex]

    That means, "A and B" or "A intersect B".

    What is in "A and B"?.

    That is, what do they share?.


    Those elements are in both sets. If you draw a Venn diagram, they would be in the intersection of the two circles.
