William F. White was a professor of mathematics at State Normal School in New Paltz, New York and held a PhD from Colgate University. He was also, very clearly, a lover of mathematics. A Scrap-Book of Elementary Mathematics: Notes, Recreations, Essays is White's love letter to math. White makes it clear early in this work that this is not a resource guide or a textbook. Rather, White has created a volume consisting primarily of puzzles, notes, and intriguing principles of mathematics. Essentially, this is the fun side of math. Repeating products, algebraic fallacies, axioms in elementary algebra, and the law of commutation are just four of the intriguing principles discussed. The real strengths of the work are the mathematical games and puzzles presented throughout. Each section of the book is brief, with topics covered in only one or two pages, and the author keeps the book moving at a rapid pace. Bibliographic notes and a detailed index conclude the work.
