Hi, I'm new to this with Venn diagrams and set theory so I'm wondering how am I supposed to draw a Venn diagram and mark the areas? I get that A union B is two circles that I can mark and that C is an intersection that I can mark, but what about D? Does this mean that D is a circle around $\displaystyle \displaystyle ((A \cup B) \cap C)$? But this doesn't seem correct since I have to mark the whole area of D which includes A, B and C. $\displaystyle \displaystyle ((A \cup B) \cap C) \cup D $ Thx for replies and suggestions.

$\displaystyle ((A\cup B)\cap C) \cup D$

But why is A and B not marked since $\displaystyle \displaystyle A \cup B$? Is that because of the whole operation with the intersection C at the end? D makes sense to me since it is a union of A and B and also union of intersection C.

Was any guide given regarding how much is annotated?

No, it was not.
