Algebra, Philosophy, and Fun

I don’t often encounter the words “philosophy” and “fun” right next to the term “algebra.” Nowadays, these words don’t seem to fit together comfortably. However, the three terms do appear in the title of an engaging little book called Philosophy and Fun of Algebra, written by Mary Everest Boole (1832–1916) and published in 1909.

I discovered the book while browsing the online Cornell University Library Math Book Collection (http://moa.cit.cornell.edu/dienst-data/cdl-math-browse.html),
