Lesson Summary:

Learn how to find the intersection and union of sets using a Venn diagram with this lesson. The universal set is represented by a box, with subsets A and B contained inside. The sets are denoted with brackets, and the intersection is found where the sets have elements in common, while the union is the combination or addition of the elements between two or more sets. By the end of the lesson, you'll be able to easily determine what elements are in a set and find the union and intersection of sets using a Venn diagram.

Lesson Description:

How to find the intersection and union with sets in a venn diagram

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
