Spice up the first five minutes of your high school and lower-division college math classes with Mudd Math Fun Facts.  Fun Facts are designed for, and work best in courses where the typical student needs that boost to generate interest and arouse curiosity in math.  The Fun Facts will cause students who are studying algebra, geometry, probability, calculus, number theory, and topology, for example, to look at mathematics differently! Taken from the quick activity on multiplication by 11, can you figure out what's going on here? 253 x 11 = 2783 117 x 11 = 1287 532 x 11 = 5852 267 x 11 = 2937
