HOW TO USE ITIf you want examples from a specific base to a specific base: Use the to-base and from-base sliders to set the bases. Now press the setup button. This will generate a random number in the from-base to be converted to the to-base. Note that it is possible to have leading zeroes.
If you do not care which bases are used, click the random button to generate an arbitrary problem.
The slow-motion slider is an easy way to adjust the speed of the display. Set it to zero if you want to show the final result as quickly as possible. 0.3 is a good setting for most purposes.
The step button does the next step of the conversion process. It then stops so you can take notes. This is useful when you are first learning the method.
The go button does all the remaining steps, at a speed determined by the slow-motion slider. This is useful when you do not need to take notes between each step, or do not wish to press the step button five times to get an answer. If you want to pause the demonstration, simply click the go button a second time and it will stop after it finishes the current step. You may then click go a third time to resume.
The quiz button will generate a random problem. Spaces and commas in your answer will be removed, so feel free to use them to help you count the digits. Lower case letters will be automatically changed to upper case.
The show-again button starts the exact problem from the beginning. You may then click either the step button or the go button to see the same demonstration.
Applets on this website were written by Teresa Carrigan in 2004, for use in computer science courses at Blackburn College, with the exception of the Fireworks applet. The applets made with NetLogo require Java 1.4.1 or higher to run. The applets made with NetBeans require Java 1.4.2 or higher to run. Applets might not run on Windows 95 or Mac OS 8 or 9. You may obtain the latest Java plugin from Sun's Java site.
