What is the Chinese abacus method?

The Chinese abacus method, known as Zhusuan (珠算), is an ancient system of calculation using the suanpan (abacus) for addition, subtraction, multiplication, division, and roots, relying on moving beads with specific finger techniques to represent numbers and perform algorithms, eventually allowing for rapid mental calculation by visualizing the abacus. It uses a frame with rods holding beads (heaven beads worth 5, earth beads worth 1) and operates on place value, acting as a physical computer that developed complex mathematical skills.

How does the Chinese abacus work?

The beads are usually rounded and made of hardwood. The beads are counted by moving them up or down towards the beam; beads moved toward the beam are counted, while those moved away from it are not. One of the top beads is 5, while one of the bottom beads is 1. Each rod has a number under it, showing the place value.
