"Design and text by Lawrence Swienciki, PhD."--Poster. Title from poster.

The poster's central panel depicts two Korean scholars doing calculations using calculating rods on a rectangular grid board set on a low table. A woman with an elaborate hairstyle, and a child are watching. Columns on outer left and right show the placement of rods to represent numbers, including place value, plus the steps involved in solving a multiplication and two algebraic problems. The text box at the bottom outlines the history of the rods system, and explains in detail how the problems in the columns are solved.
