A subset of a set \(A\) is another set that contains only elements from the set \(A\), but may not contain all the elements of \(A\). Suppose a set contains the plays “Much Ado About Nothing”, “MacBeth”, and “A Midsummer’s Night Dream”. What is a larger set this might be a subset of? The set \(A=\{1,3,5\} .\) What is a larger set this might be a subset of?
- https://math.libretexts.org/Courses/Angelo_State_University/Finite_Mathematics/09%3A_Sets_and_Probability/9.01%3A_Basics_of_SetsA mathematical set is an unordered lists of things. The "things" in the sets are called elements. This section introduces sets and the notation and vocabulary we use to talk about them.

The absolute value of a real number \(a\), denoted \(|a|\), is defined as the distance between zero (the origin) and the graph of that real number on the number line. There are two solutions: the distance to the right of the origin and the distance to the left of the origin, namely, \(\{\pm 5\}\).

We want to be able to both read the various ways and be able to write down the representation ourselves in order to best display the set. We have already seen how to represent a set on a number line, but that can be cumbersome, especially if we want to just use a keyboard.
