THINGS TO NOTICE

While you count, watch the bottom blue line that displays the decimal equivalent. Determine an algebraic expression for the range of possible decimal equivalents, given the number of digits and the base.

THINGS TO TRY

Set the slow-motion to about .10 seconds (or slower) and press the increment button a few times. Watch the red arrow change digits, and notice when it decides no more digits need to be changed.

What happens when all the digits are one less than the base, and you increment again?

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.
