Set Theory And Notation
Gbogbo ọrọ náà
Every time you filter search results, group customers by two overlapping criteria, or ask how many students take both Physics and French, you are reasoning about sets. Set notation gives that reasoning a precise, compact language instead of long sentences.
You will use curly-brace notation and membership symbols, work with union, intersection and complement (including sets defined algebraically), count elements with the \(n(A)\) notation, and solve two- and three-set Venn diagram problems, including ones where a region is left as an unknown to find by equation.
