THINGS TO NOTICE

When the base is 2 (binary) the digits are only 0 and 1. In this case, you don't really need the third step (multiplying); just add the place values for the digits that are 1, dropping the digits that are 0.

When the base is smaller than ten, the decimal equivalent will have at most the same number of digits as the original number, and usually it will have fewer digits. When the base is larger than ten, the decimal equivalent will have at least the same number of digits as the original number, and usually it will have more digits.

THINGS TO TRY

Set slow-motion to 0.5, click random, and then click go.

Set the sliders to a problem type you want to drill, then click setup. Attempt one step at a time on paper, and then click the step button to check that you did that step correctly.

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.
