Course Description

An understanding of algebra is a foundational skill to virtually all topics in higher-level mathematics, and it is useful in science, statistics, accounting, and numerous other professional and academic areas. This course builds a bridge between simple whole-number arithmetic operations, such as addition, subtraction, multiplication, and division, and algebra.

This course begins by reviewing the basic arithmetic operations and their mutual relationships, and it then goes on to develop an understanding of fractions and how to perform operations on them. Exponents and their properties are then derived, and radicals (and other roots) are presented.

This course shows how exponents and roots are related, as well as how these are related to multiplication and division. Throughout this first portion of the course, the use of symbols in place of numbers is introduced and developed, leading to an investigation into variables and algebraic relations in the latter portion of the course.

This course also describes how to graph algebraic relations and how to solve simple linear equations. Finally, the course applies these various concepts to geometry by considering some of the characteristics of triangles, rectangles, and circles, and it also applies them to basic probability and statistics.

Thus, this course not only provides a fundamental set of algebra skills, but it demonstrates how these skills can be used to study various problems that have real-world applications.

  • Lesson 1 - Review of Basic Operations

    This lesson reviews the basic operations and some associated ideas, setting the stage for learning about fractions, the first main topic of the course.

  • Lesson 2 - Fractions I

    This lesson provides a foundation for understanding how to add, subtract, multiply, and divide fractions--a topic to which we will turn in the next lesson.

  • Lesson 3 - Fractions II

    In this lesson, we apply our fundamental understanding of fractions from the previous lesson to the basic arithmetic operations.

  • Lesson 4 - Decimals, Percents, and Ratios

    In the previous two lessons, we discussed fractions at length. As you have probably noticed, however, most basic calculators (as well as many more-advanced calculators) do not deal with fractions.

  • Lesson 5 - Exponents I

    In this lesson, we introduce exponents, which are a way to represent repeated multiplication (just as multiplication is a way to represent repeated addition).

  • Lesson 6 - Exponents II

    Specifically, this lesson considers rules for multiplying and dividing expressions with exponents, and it also explores the meaning of negative exponents.

  • Lesson 7 - Radicals I

    By the end of this lesson, you should be able to handle numbers raised to any exponent, and you will also be equipped to study arithmetic operations on radical expressions in the next lesson.

  • Lesson 8 - Radicals II

    The mathematical tools we study in this lesson allow us to at least partially evaluate radical expressions without losing exactness in the result (unlike what would happen if we simply used a calculator).

  • Lesson 9 - Variables and Algebraic Relations

    This lesson focuses mainly on the concepts associated with these topics and lays a foundation for studying in later lessons how to graph relations and solve simple equations.

  • Lesson 10 - Graphing Algebraic Relations

    In this lesson, we learn how to graph simple and moderately complicated algebraic relations.

  • Lesson 11 - Solving Linear Equations

    In this lesson, we learn how to manipulate equations by performing operations on both sides of the equation

  • Lesson 12 - Geometry I: Rectangles and Triangles

    In this lesson, we take what we have learned about numbers, operations, and variables and apply it to simple geometry.

  • Lesson 13 - Geometry II

    In this lesson, we apply our basic algebra skills to the properties of circles. We look at the circumference and area of a circle, and we introduce the number pi (π)

  • Lesson 14 - Introduction to Probability

    In this lesson, we take some of the principles we have learned in previous lessons and apply them to some simple concepts and problems in probability.

  • Lesson 15 - Introduction to Statistics

    The final lesson of this course looks at statistics, which is a subject that is closely related to probability.

Student Testimonials

  • "Excellent Course. The instructor made this an enjoyable online experience and the lesson topics and layout will help me become a better math teacher." -- Annette K.
  • "I really appreciated how April went above and beyond. In one test, I was completely baffled by a question but I had guessed the correct answer, so I didn't receive the explanatory text as one does for incorrect responses. I emailed April with the details of the question that I recalled and asked for her help in understanding it. She tracked down the question and helped me understand the correct response. Many instructors will help you understand questions you get wrong, but April helps to make sure that you understand the questions that you get right too - so that in the future your correct response is not an accident!" -- Rachel B.
  • "The instructor followed my test and exercise results very promptly. I didn't think she would be available on weekends." -- Harry T.
  • "The instructor graded all of my exams quickly and provided prompt responses to my questions." -- John A.
  • "The instructor was very timely with the results and feedback of my exam." -- Serena V.
  • "Very helpful and quick to reply to my emails." -- Frieda F.
  • "My teacher did a great work." -- Sunghee M.
  • "What I liked most were the tests and assignments. It evaluates my knowledge." -- Sunghee M.
  • "What was most helpful were the detailed course lessons and the examples provided. Instructor was very knowledgeable and was very good about giving detailed feedback to correct any mistakes or misunderstandings." -- William Hunter R.
  • "I enjoyed this course. I'm also glad I could get on this course as often as I could. I liked the 5 exercises before the assignments in each chapter, plus the videos helped. The break down of the material was good too. Also I noticed that the assignments and the exercises addressed my working knowledge of my work and the test addressed my verbal knowledge, which is good. I notice that I have some problems with verbal knowledge. This has to do with me and maybe a health problem. I'm glad to know this. It tells me what to work on." -- Debbie E.
