(credit: "Time to assemble more Ikea furniture!" The above represents a Venn diagram. The universal set is the set of all positive integers. Let represent the set of multiples of 7; let represent all of the multiples of 11; let represent all of the multiples of 13. As you can see, the three sets divide the universal set into eight regions. Set notation is used to describe different regions close region An identified area on a diagram or graph. on a Venn diagram:. ξ represents the universal set.; A represents set A and B represents Take a look at a different problem solving exercise using Venn diagrams.

Venn diagrams include rectangles and closed curved circles. Rectangle shape is the universal set and its subsets are closed circles. Venn diagram illustration of equal sets is shown below: Venn diagram shown above includes two equal sets P and Q as there is the same number of components with equal elements, i.e., P = {2, 7, r} = Q. Properties
Set notation uses curly brackets { } which are sometimes referred to as braces. Objects placed within the brackets are called the elements of a set, and do not have to be in any specific order
Unit1Mod2. UNIT 1 MODULE 2. VENN DIAGRAMS AND SET OPERATIONS. A Venn diagram is a drawing that shows the general relationship between sets without listing any of the specific elements of the sets.
