What it is
Summary
AI-generated from vendor-published content · June 8, 2026
A traditional bead abacus with 13 rows of sliding beads that lets users perform arithmetic through direct physical manipulation — adding, subtracting, multiplying, and dividing by moving beads along rods. This kind of tactile calculation tool is particularly useful for people who are blind or have low vision, since it provides a non-visual, hands-on alternative to written or screen-based math. It's a complete, standalone tool — no batteries, software, or accessories required. The 13-row configuration handles numbers into the trillions, which covers most practical arithmetic; if you need a wider range of simultaneous calculations, the 15-row version offers a bit more capacity.
