Demonstration of the Distributive Law

This Java applet shows the distributive property in action. Toggle to change the height and width of a rectangle, the side lengths of which represent two factors; click on any interior edge of the rectangle's unit squares to create a new re-grouping. An expression appears at the bottom displaying the numeric representation of the new groups, illustrating the distributive property.

    • This application provides nice visualization of the distributive property. However that is really all it does and not much more.
