 Combining Like Terms (Simplify Expression & Vocabulary for Expression) In the first part of the video, I compare an expression to an equation, and then I describe the meaning of some important vocabulary.  Next I show how to simplify two expressions.  In the second part of the video, I show how to simplify three more expressions, from a worksheet of twelve. It may help to print "Sheets Used in Video"  to have them for writing notes as you watch the video. The worksheet has three columns, each with a similar variety of problems. I suggest completing one column and learning from mistakes before attempting the next column.

 Introduction to Solving Algebraic Equations In this first video I describe what it means to "get x by itself."  I then present how to solve algebraic equations, based on using two questions, while going over eleven "one step" equations.  For the sake of illustration, a few of the equations are all variables, no numbers. My intention is for viewers to watch both videos in succession; the "3 Pages for 2 Videos" link opens the two pages that are used in the first video, as well as the third page which is used in the second video. 3 Pages for 2 Videos 3 Pages for 2 Videos (Answer Key) Rules- Intro to Solving Algebraic Equations Comment is not working; I hope to fix it by early 2018. Assuming familiarity with concepts covered in the first video, I present how to solve algebraic equations that are "more than one step."  I solve five more equations.  The last two equations start with the variable on both sides of the equal sign. These Practice Worksheets assume familiarity with concepts covered in both of these Introduction to Solving Algebraic Equations videos.

 Solving Algebraic Equations (Simplify First, Some Parentheses) Building on concepts from the previous two videos, I solve five algebraic equations.  They involve simplifying one or both sides of the equation prior to "getting rid of" terms on either side. The practice worksheet has three columns of four problems each.  I recommend NOT doing all twelve problems in one sitting; take a break of minutes or hours between columns, and strive to complete a column correctly--without looking at notes or examples.  This helps to move knowledge from short term to long-term memory.
