Mathematical recreations
The puzzles in this book have a format that will be familiar to all who have engaged in puzzle solving. Some of the types are:
*) Crossnumber puzzles
*) Logic puzzles
*) Arithmetic operations where blanks must be filled in
*) Liars and truth tellers
I spent a large amount of time working through many of the puzzles. For some of them, the solution was almost immediate, yet for others I ground away at it for some time. None of them are extremely difficult; all can be solved with persistence and dedication, although in most cases a scratch pad is essential. Solutions to all 102 of the puzzles are included at the end.
