Chinese Abacus (Suanpan) - History, Design, and Use in Ancient Mathematics #1778047 (License: Personal Use)

This image shows a traditional Chinese Suanpan abacus with a two-five bead configuration per rod: two upper beads (each representing 5) and five lower beads (each representing 1). Crafted from wood and metal, it enabled rapid arithmetic operations including addition, subtraction, multiplication, and division before modern calculators. The design reflects centuries of refinement in East Asian computational practice.
