Using a problem involving the perimeter of a rectangle, Sal Khan demonstrates how to solve for a variable (the width of the perimeter). Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of th...e 2009 Microsoft Tech Award in Education. (06:58) There is a lot of information on the screen--the viewer may want to open the video to 'full screen.'

In this video segment from Cyberchase, Jackie, Matt, and Inez try to move a stack of slabs blocking a doorway. They decide to use a long board as a lever, but they soon realize they need a longer board in order to move the heavy slabs. The problem is... that they are not sure exactly how long the lever should be. Since they do not have the time to try out levers of varying lengths, Inez decides to construct a scale model. While testing their model levers, they learn about the relationship between the length of a lever and its lifting capability. (4mins)

The goal, as always, is to isolate or "solve for" the variable. You can
undo any addition or subtraction using inverse operations. An example problem is shown and solved using a marker on the screen. Loud music plays in the background of this vide...o that distracts from the math problem.
