Description:

This Java applet offers an interactive version of the standard "long" multiplication algorithm. Click any digit of either multiplicand slightly off-center (left to increase, right to decrease) and watch the corresponding products change accordingly. In addition to check-boxes to toggle the appearance of trailing zeros and other display choices, the applet also lets you change bases -- from base 3 to base 36.
