Misteaks [sic] and how to Find Them Before the Teacher Does
This unusual, but very useful, 'how-not-to' book is available in a second edition which eliminates most involuntary mistakes. Three well-known teachers have testified to its value: Ross L. Finney, coauthor of Calculus and Analytic Geometry; Philip J. Davis, coauthor of The mathematical Experience; and Ralph P. Boas, former editor of The American Mathematical Monthly.
