"Abstract: Join us as we explore the hyperreal number system, which adds to the real numbers by including infinitely small numbers (infinitesimals) as well as infinitely large numbers, and lots of them – infinitely many different sizes of infinitely large numbers! This playground has an interesting history as well as connections to ideas in calculus and other subjects."
