If you want to get more fancy with sets, you can explore set-builder notation. A set is a collection of things, called elements. I've used the vague word, "things," because the elements of a set can be whatever we want them to: numbers, words, people, or even sets! We often describe a set by listing its elements and putting brackets around them, for example:.
Here are some things we might say about a set, so that you can learn how to talk about a set and its elements:. Then S has four elements. For example, 1 is an element of S. But 4 is not an element of S. The set S also contains 2, but it doesn't contain 5. Why are sets defined this way? One reason is because most mathematicians think of sets as the most fundamental mathematical things, and they've found ways to describe everything else even numbers! Because of this, sets are defined to be as simple as possible.
This video by primethinker explains sets and set notation. The objects in the set are called the elements or members of the set. They are groups of numbers when used in math, but they can be groups of any type of object or word. He then looks at some examples. The first is a bunch of CDs from The Beatles. These CDs form a set and each element is one of the CDs. If we were asked how many elements are in our set, we just count them.
This is the same as asking how many CDs do we have in our Beatles collection. Sets are generally written in curly brackets. What are Sets?
