We introduce an integral affine structure on a conic, through an elegant but simple geometrical product of points. This appears to have been first explained in the book “Elliptic Functions and Elliptic Integrals” of Prasolov and Solovyev in 1997, and then independently by Franz Lemmermeyer. They all realized that the famous product structure on a…
