So there you go. You have the union of X and Y. And one way to visualize sets and visualize intersections and unions and more complicated things, is using a Venn diagram. So let's say this whole box is-- you could view that as the set of all numbers. So that's all the numbers right over there. We have set X-- I'll just draw as circle right over

The complements of sets A, B, C… are denoted as A’, B’, C’,… and so on. Excluding all the elements of a given set from the universal set gives us the complement of that set. Venn Diagram of Complement of Set. The following Venn diagram shows the universal set U and its two subsets- A and A’.The union of two sets A and B is the set of elements which are in A, in B, or in both A and B. It is one of the set theories. Here is a simple online algebraic calculator that helps to find the union of two sets. Enter the value of set A and set B as shown and click calculate to obtain the union of two sets. (A union B) is represented as (AUB).A Venn diagram, sometimes referred to as a set diagram, is a diagramming style used to show all the possible logical relations between a finite amount of sets. In mathematical terms, a set is a collection of distinct objects gathered together into a group, which can then itself be termed as a single object. To correctly understand Venn diagrams, you must know the name of each of the components that make up the diagram: Union. These are the sets of information or elements that you represent in the Venn diagram, which are usually in the shape of a circle or oval. Set. The union of all the sets or circles of the Venn diagram. Intersection. zip, 59.57 MB. This is a whole lesson on Venn Diagrams, Set Notation, and Two Sets. It looks at what sets are and how to shade a region given a description. The lesson also looks at writing a description given a shaded set.
