In James Tanton's Intersection Math problem, two rows of dots are drawn and then all dots in the top row are connected to all dots in the bottom row. He then defines "multiplication" (denoted in our work as the star operation) to be the number of intersections produced by all the lines. We solved this problem and then extended it to tripartite graphs.
