The abacus is as useful and effecient a machine today as it was when it was first created centures ago. Whether you're an expert in the latest computer technology or you're mastering arithmetic and word problems for the first time, it won't take long to learn the basics (and even the not-so-basics) of adding, subtracting, multiplying, and dividing on this ingenious and fun-to-use mathematical tool.
The world's first computing system, the abacus was an ingenious invention designed to perform speedy calculations through the movement of beads on a series of rods. The new edition of Dilson's marvelous book is even more user-friendly that the original; it comes with a working abacus that can be used in concert with its easy-to-follow and clear illustrations.
