|The following review of Michael Henle's Which Numbers Are Real? was published as an MAA Review in October 2012.|
"My final impression of the book is very positive. Although the subject of the book is just numbers, the collection of number systems outlined in the book serves to demonstrate the breadth and power of mathematical methods and surprising diversity of properties and proof techniques even within related topics. The book should be welcomed by mathematically inclined high school seniors, college undergraduates and their instructors."
