How to Use this Applet
This program shows the stages you need to do in order to perform a long division of algebraic expressions. In this case it is a cubic expression divided by a linear one, but the technique can be easily extended to more complex cases. Every time you click "New Problem" you get an new random division to do. If you tick the box labelled "harder", the problems set will be a little more difficult. If you tick the box labelled '"remainder", the divisions will have a remainder.
Clicking the "Next Step" button shows the next stage of the calculation, and an explanation at the bottom of the screen. At the end the solution to the problem is given. To get the most out of this you should try to follow and understand each stage thoroughly. If you can do this kind of thing your confidence in algebra will improve. Good luck!
