Mathematics One challenge in writing a book such as this is to find a way to communicate to a wide audience without sacrificing a high level of understanding of the subject. So I have tried to strike a balance between the many who would want to see less math and the few who would want to see more.
Extensive use is made of arithmetic and algebra.
Some, but infrequent, use is made of calculus. Most of the concepts needed from statistics are supplied by the text, but even so readers will find they are better served if they have already had an introductory course in this area. Nonetheless, much of the Picture Book can be understood with limited mathematical knowledge. For example, excepting portions of section 1.1, all of Chapter 1, which provides an introduction to derivatives, can be understood without any knowledge of mathematics. One way to handle this is to alert the reader when some of the more mathematically intensive portions of the book can be skipped with little loss of understanding, or when the current topic will require extended numerical calculations.
