Sets
Akopọ
A set is simply a collection of things, and once you have a precise way to talk about collections you can describe almost anything in mathematics: the factors of a number, the solutions of an equation, the students who study both French and Spanish. Sets give you the exact language, and Venn diagrams give you the picture.
In this lesson you will learn the symbols mathematicians use for sets, how to read and write them, and how to draw and interpret Venn diagrams. You will work with the union and intersection of sets, the complement of a set, and (for Extended) the relationships between sets such as subsets. These tools reappear later in probability, so they are well worth mastering.
