How to Count : An Introduction to Combinatorics and Its Applications

“The book is an excellent introduction to combinatorics. ... The author uses a clear language and often provides an easy intuitive access to abstract subjects. The presentation is well motivated, the explanations are transparent and illustrated by carefully selected examples. Each section ends with a list of well formulated exercises which make the book ideally suited for self-instruction.” (Astrid Reifegerste, zbMATH 1328.05001, 2016)

“This book by Beeler ... is an excellent introductory text on combinatorics. The author gives the right balance of theory, computation, and applications, and he presents introductory-level topics, such as the multiplication principle, binomial theorem, and distribution problems in a clear manner. ... Summing Up: Highly recommended. Upper-division undergraduates through researchers and faculty.” (S. L. Sullivan, Choice, Vol. 53 (1), September, 2015)
