Talk:Ideas in Geometry/Instructive examples/Section 2.1 Basic Set Theory number 10

This problem looks really good! I just had a couple suggestions. There is a spelling error the first time you use the word “denote” (just that it has an “s” on the end). For step 1 (finding X U(Y∩Z)) I might suggest making the visual a little easier to follow just by putting a fully shaded X + what you found for (Y∩Z) then showing how they come together. I feel this might help people follow along more easily especially for part 2 of the problem, which is a little more difficult. Also at the end, possibly showing the two sides of the equation side by side again for visual affect and clarity. The problem looks great, the written explanation describes your process very well, the organization of steps is clear, and your images looks really good! Nice work!

I liked how you had pictures for explaining the problem. Your wording on a lot of things was really confusing though. Some pictures are not clearly explained, make sure you explain each photo, not one explanation for two photos. Like explain the picture XU(Y∩Z), it seemed like you only really explained the picture Y∩Z. show how you got from that picture to the new one.
