Do any of you have a good calculator that I can use for this or are any of you willing to spoonfeed me the answers for like five of these questions?

maybe i'm not getting the task at hand - but there's nothing to calculate? it's just logic and notation...

just get a piece of paper, draw the number line, check what the sets mean. Write them as intervals.

B and C are disjoint (there is no x that is <= 1 and > 8 at the same time). What does it mean for the intersection of the two sets? What about the union?
