Nishika, please give explanations instead of answers.

Answer 2

Okay thank you! :)

Answer 3

Megan, the "upside down u" means "intersection" or "overlap."
When you see it, you get a new set that only has the things that were in both sets.

AnB is a suitable alternative to writing out "upsidedown U" :)
