Historical Abacus Illustration - Ancient Calculation Tool #1778042 (License: Personal Use)

This black-and-white woodcut-style illustration depicts a traditional abacus with four horizontal rods and alternating black and white beads, typical of historical East Asian or European counting frames. The beads are arranged to represent a specific numeric value, demonstrating how users perform addition, subtraction, multiplication, and division manually. The rustic linework suggests an archival or educational print from a pre-modern mathematics textbook.

Used in educational articles, museum exhibits, or history-of-math web pages to illustrate early computational tools; targets users researching ancient numeracy systems, STEM pedagogy, or cultural artifacts.
