Abstract
This paper outlines the history of a famous school mathematics problem ? originally formulated (we believe) by Isaac Newton. It appeared in a U.S. arithmetic text in 1834 and became the source of a controversy that lasted for at least 60 years. We offer two quite different solutions to the problem and provide details of the controversy that emerged. The concept of mathematical elegance, and the difficulty of specifying criteria for elegance, are discussed.
