Mathematical Wrinkles - For Teachers and Private Learners Consisting of Knotty Problems; Mathematical Recreations Answers and Solutions; Rules of Mensuration; Short Methods; Helps, Tables, Etc #228064

Originality is not claimed for all of the problems, but for many of them. They have been compiled from various sources. The author's aim has been to select problems not only instruo tive, but also interesting and amusing. The rules of Mensuration and Short Methods have been included because of their usefulness. On account of the vari ous helps placed in this book, it will serve as a handbook of mathematics to both teachers and pupils. The solutions to only part of the problems are given. In some cases solutions of considerable length are given, but at other times only the answers are given. Had the full solu tions and proofs been given in every case, either half the prob lems would have had to be omitted, or the size of the book greatly increased.
