January 31, 2009Lesson 19: Simplify Complex Rational Expressions This video shows how to simplify fractions within fractions (known as "complex rational expressions). Just find the Lowest Common Denominator (LCD) and multiply all the fractions by it....more January 31, 2009Lesson 18: Add and Subtract Positive and Negative Numbers This lesson teaches a method for adding and subtracting positive and negative numbers. (Other than the number-line method)...more January 31, 2009Lesson 17: Matrix Addition How to add two matrices together. If they both have the same dimensions (same number of rows and columns) then you just add up the numbers that are in the same spot....more January 31, 2009Lesson 16: Solve Systems of Linear Equations by Substitution This is the last video in a series about systems of linear equations. This lesson looks at how to solve systems by substitution. Isolate (get by itself) one variable and plug the result into the other equation. Plug the answer back into one of the original equations....more January 31, 2009Lesson 15: Solve Systems of Linear Equations by Elimination Part 3 of a 4 part series on systems of linear equations. This lesson looks at how to solve systems by elimination. Combine both equations together so that one variable cancels out. Then solve for the single variable and plug back into the original equation....more January 31, 2009Lesson 14: Solve Systems of Linear Equations by Graphing Part 2 of a 4 part series on systems of linear equations. This lesson looks at how to solve systems by graphing. Simply graph both equations on the same coordinate plane and look for the intersection, if it exists....more January 31, 2009Lesson 13: Solve Systems of Linear Equations Intro This lesson is the first of a four part series about systems of linear equations. Here, I define what a system of equations is, and the three types of solutions. Future lessons will cover graphing, elimination, and substitution....more January 31, 2009Lesson 12: Simplify Radicals This lessons looks at how to simplify radical expressions which are not perfect squares or cubes. I include an example of square root, cube root, and 4th root. I show a technique to simplify n-root expressions. Also I look at how to simplify variables in radical expressions....more January 31, 2009Lesson 11: Solve Equations that have Absolute Value ...more January 06, 2009Lesson 10: Graphing Inequalities ...more
