|Interactive Mathematics Miscellany and Puzzles, Alexander Bogomolny|
|A Java simulation of the Chinese Soroban--a far eastern analogue of the traditional abacus. By splitting the field into two parts--the earth and the heaven--Soroban cleverly reduces the number of items that represent a single digit. The simulation enforces carrying, thus helping students grasp the concept of the positional, decimal in particular, number system.|
