Section 1: Introduction to Set Theory

1 Lesson 1 – Set Theory 05:13

Numbers that share specific characteristics can be "put" into unique sets. It's not unlike a set of dishes; each dish shares a certain characteristic. It's the same concept with numbers; a set of numbers are a group of numbers that share a common characteristic.

4 Lesson 3 – Symbols Used in Set Theory 02:48

5 Lesson 4 - Set Notation 12:35

Set Notation

There are many ways to represent a set of numbers. Below are the main two types of set notation.

7 Lesson 5 - Subsets 03:07

Sets and Subsets

Any set "contained" inside another set is called a subset. Another way to think about a subset is any set which all the elements of a set are contained in another set.

Example: Let A = {1, 3, 5, 7} and let B = {x|x ∈ N}, then A is a subset of B (all elements of A are contained in B).

We write subsets like this: A ⊆ B (The set A is a subset of set B.)

A proper subset is a subset that does not contain every element of the original set. So, we can also say that the set A is a proper subset of set B: A ⊂ B.

Example: The set of Natural numbers is a proper subset of the set of Whole numbers because the set of Natural numbers does not contain the number 0.

N ⊂ W (The set of Natural numbers is a proper subset of the set of Whole numbers.)

All sets are also subsets of themselves, but not proper subsets of themselves.

Example: N ⊆ N (The set of Natural numbers is a subset of itself.)

TARGET AUDIENCE

This is a robust 11^th grade algebra course that was designed for high school students planning on attending, and graduating from, college.

COURSE REQUIREMENTS

Students taking this course should ALREADY have basic algebra skills, i.e., arithmetic with fractions, decimals, and percents; arithmetic with integers (a negative multiplied by a negative is a positive); how to algebraically move a variable and/or a constant from one side of an equation to the other side; you know - the absolute basics of algebra. A graphing calculator would be nice but not necessary. A calculator that can calculate exponents and logarithms is needed.

THIS COURSE INCLUDES

140+ video tutorials
Guided homework worksheets covering every concept (answer sheets with video explanations)
8 tests (one for each section)
3 Midterms + 3 Practice Midterms (with answers)
1 Final Exam + 1 Practice Final Exam (cumulative, with answers)

Teacher: Richard
Areas of expertise: Algebra, Statistics and Probability, Trigonometry, Calculus, Discrete Math, Linear Algebra, How to Teach Math (for future Math instructors), Business Math, and others.
Education: BA in Mathematics (SDSU), MA in Curriculum and Instruction Emphasis in Math Instruction (SDSU), BCLAD Teaching Credential (SDSU)
Interests: Watching students succeed in mathematics, Emerging Learning Technologies, Puzzles, Soduko, Space Exploration, Science Fiction, Zombie movies (good ones, not those cheap ones!), Music, Video Production, Website Construction, World Peace, Family, others
Skills: I have an easy non-threatening approach to the teaching/learning of mathematics. I break down the harder concepts into easier to understand steps. I am one of those weirdos who actually loves math. I see math like art and/or music - it gives me goose bumps!

Issues I care about: I am very concerned with how our country has watered down math education in our public schools. There is no doubt that the courses that keeps students from succeeding in high school and/or college are all mathematics courses. I don't blame the students - I blame the educators; not the teachers, but the Educational Leaders who make the big decisions. Public school teachers have zero choice in what and how to teach math.

I have been a Math Learning Specialist and Director of our University's Tutoring Center for the last 15 years. I have personally worked with thousands of struggling math students. I have also taught all of the math courses that our school offers, at both undergraduate and graduate level. A very sad fact is that around 90% of our incoming students are not prepared for college level mathematics. For some strange reason, students who are not successful at math in high school believe that they will understand it when they get to college - just the opposite is true. Students who master the concepts covered in this 11th grade course will succeed in their math courses in college.
