In this lesson, we learn about sets and set notation. A set is a collection of objects, subsets are sets within a set, and an element is an object in a set. The universal set is the collection of all elements, while a regular set notation is a name of a set, containing symbols, intersections, and unions. Through this lesson, we understand how to define sets and set notation.

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.
