Book entry:

A set is a collection of distinct objects. Each object in a set is called a element or member of the set. You can use set notation to write a set by enclosing the elements of the set in braces. (__(_)__)

Me: Example, if A = less than 6, A = 1, 2, 3, 4, 5.

Book entry:

KEY CONCEPT:

The union, U, is the set of all elements(numbers) in either A or B and is written a A U B

Me:

(A_(_)_ U<-- All numbers that don't fit the requirements of A or B go outside, being U.

Book entry:

The intersection of two sets A and B is the set of elements in both A and B and is written as A (upside down U) B.

End entry.

Me: I still don't understand intersections.

Hope this helped.

Oh, well it seems you have union down. Good luck on intersections! I pretty much think its the same thing.
