Solving Non-Standard Very Hard Problems

This unique book will help master your problem-solving skills. It contains many very hard Non-Standard-Problems (NSP), which can be solved by using creative thinking instead of formulas or predefined steps. For most problems, you do not need to know any advanced mathematics or have any specialized knowledge. For a few of the problems that are about the chances of something happening, you might need some limited knowledge about probabilities, provided for your convenience in the Appendix.



This book will help you develop and master your critical, "out of the box" thinking. Most problems are new, but some were inspired by well-known problems.

The book also includes some easier problems, puzzles, and jokes to warm up; they also make it enjoyable to read not only for adults but for children as young as 10. It is written in a fashion that is easy to understand. This book concludes two previous books on mastering creative problem-solving skills: "Yes/No Puzzles and Games" and "Solving Non-Standard Problems".



Don't give up quickly, but if you are out of ideas on how to solve particular problems, check out the solutions sections for comments and useful hints. As you work through the book, this will help you solve the next round of problems.
