### 198 Algebra Basics Videos by Khan Academy.zip

These 198 Algebra videos take students through a thorough review and practice of the core concepts in Algebra. They will also help prepare for high school or college placement exams, covering all of the foundational areas in algebra and related topics in pre-algebra and geometry. For further advanced topics and material, please look at our Algebra I and Algebra II video pages.

#### Topics Covered by these 198 Algebra Basics Videos:

**Foundations of Pre-algebra Skills – 52 videos**

This topic isn’t algebra, but it is a survey of all of the most important pre-algebra skills you need to really digest algebra. These skills also tend to be pretty important in life in general!

**Algebraic Expressions – 15 videos**

The core of idea in algebra is using letters to represent relationships between numbers without specifying what those numbers are! We use letters or variables to represent the parts of the expression that may take on different values or is an unknown that we can solve for.

**Linear Equations and Inequalities – 37 videos**

We will now equate two algebraic expressions and think about how it might constrain what value the variables can take on. The algebraic manipulation you learn here really is the heart of algebra.

**Graphing Lines and Slope – 37 videos**

Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). This will include slope and the equation of a line.

**Systems of Equations – 6 videos**

Solving a system of equations or inequalities in two variables by elimination, substitution, and graphing.

**Expressions and Equations with Exponents – 10 videos**

Let’s build our toolkit that allow us to manipulate exponents algebraically.

**Quadratics and Polynomials – 28 videos**

We’ll now progress beyond the world of purely linear expressions and equations and enter the world of quadratics (and more generally polynomials). Here we’ll learn to factor expression that have powers of 2 in them and solve quadratic equations. We’ll also learn to manipulate more general polynomial expressions.

**Equations and Geometry – 13 videos**

These videos teach angles with triangles and polygons, triangle similarity, and the Pythagorean theorem
