Beginning information on Sets
In this lesson on sets, the teacher explains the formal definition of a set and introduces concepts like elements, subsets, union, intersection, and complement. The universal set, which is the original big set, is denoted by U, while a subset is denoted by a smaller set within this universal set. The teacher uses examples of sets of people with glasses, boys, and blue eyes to illustrate these concepts. They also explain the meaning of the intersection and union of sets. By the end of the lesson, the students will have a good understanding of set notation and basic set operations.
Some basic information on 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.

Staff Review
This lesson defines some basic terms and explains some basic concepts in sets. This is a great beginning video to watch to first learn about sets. These concepts are building blocks for further study and understanding of sets. A real-life example involving the students in the class is used in this lesson to help explain the idea of sets and subsets. Some subsets considered are students with glasses, students with blue eyes, boys, and girls. Intersection, union, and complement are also considered for subsets in the class.
