Introduction to Algebra

$119.00 (USD)

Offered in partnership with Massachusetts Bay Community College choose another school



A new session of each course opens each month, allowing you to enroll whenever your busy schedule permits!

How does it work? Once a session starts, two lessons will be released each week, for the six-week duration of your course. You will have access to all previously released lessons until the course ends.

Keep in mind that the interactive discussion area for each lesson automatically closes 2 weeks after each lesson is released, so you’re encouraged to complete each lesson within two weeks of its release.

The Final Exam will be released on the same day as the last lesson. Once the Final Exam has been released, you will have 2 weeks plus 10 days to complete the Final and finish any remaining lessons in your course. No further extensions can be provided beyond these 10 days.

Week 1
Lesson 01 - Algebra: Here to Make Life Simpler
Today we'll begin to explore Al-jabru, Arabic for algebra, which means the science of restoration and canceling. We'll go in search of algebraic solutions. On our quest, you'll learn definitions, numeric properties, and basic operations that originated from the ancient lands where papyrus was used instead of paper.
Lesson 02 - How Do You Measure Up?
How do calories contribute to weight gain? How can you make a dense cake? You'll answer these and other questions in today's lesson. You'll learn the different physical quantities, their units of measurement, and why they're important. I'll show you the dimensions of length, area, and volume and how to convert their units of measurement. You'll also learn the difference between mass and weight, and density and weight density.
Week 2
Lesson 03 - Evaluation Time Again
Today we'll talk about evaluation, but not the type of evaluation your boss or your teacher may give you … well, at least not until your final exam. In this lesson, we'll evaluate algebraic expressions by using the order of operations and the distributive property. You'll also learn translation as we translate word problems into numerical ones.
Lesson 04 - Formula: Another Name for Equation
In this lesson, you'll learn formulas for basic shapes: squares and rectangles, triangles, circles, spheres, cylinders, and cubes. You may be thinking, "This is a geometry course, too?" In a way you're correct—some aspects of geometry involve formulas, which people use in everyday life. And where there are formulas, algebra can't far behind.
Week 3
Lesson 05 - Balancing Acts: Equations
Today you'll learn how to balance equations while learning even more formulas, such as those used to calculate interest, distance, and temperature. We'll talk about how to translate these types of verbal equations into numerical ones. So this is your chance to hone reading comprehension skills, too!
Lesson 06 - Investments, Mixtures, and Percentage Changes
In this lesson, we'll calculate problems involving percentages, such as how much to invest at different interest rates to obtain optimum interest, and you'll learn how to determine a specific quantity of a component of a mixture or solution given specific concentrations. I'll also show you how to buy wisely by teaching you how to calculate percent increase and decrease, sales tax, and discounts.
Week 4
Lesson 07 - Equate It in Words
The more you practice, the better you'll be able to speak the language: the math language. Practice makes perfect! So in this lesson, you'll calculate populations, averages, lengths, and widths. You'll also learn how to calculate consecutive integers, including consecutive odd and even integers.
Lesson 08 - Proportions and Variations
In today's lesson, you'll learn ratios and how to apply them to probability and odds. You'll learn how to solve proportions involving wildlife census taking, measurement of scales, and calculation of gas mileage. You'll also find out how quantities vary in equations, whether directly or indirectly, and how to apply these variations to scientific laws and equations involving weight, area, and equations of lines. Let's get moving and try not to break any laws—scientific laws, that is!
Week 5
Lesson 09 - Uniform Linear Motion
In this lesson, you'll engage in outdoor activities such as jogging, boating, and traveling in order to solve equations of uniform linear motion. We'll talk about how to calculate distance, rate (speed), and time while going in the same direction, opposite directions, and with wind and water current.
Lesson 10 - Solving Rational Equations
Today, you'll learn how to use the formula that employs the same concept as the uniform linear motion equation. It is the job formula (or equation) and it involves rational equations. You'll calculate how long it takes to finish the job, how much of the job is done, and at what rate the job is done, depending on the number of people doing the job.
Week 6
Lesson 11 - Algebraic Rational Equations
Discover some of the natural laws that govern our universe and delve into other physics concepts such as resistance, conductance, focal length, and forces while you learn some history of D-Day.
Lesson 12 - Potpourri of Algebraic Equations
Potpourri, anyone? Test various problem-solving skills while you meet General Sherman and experience the gloominess of the Great Depression. I told you it was potpourri.
