MATH TRICKS, BRAIN TWISTERS, AND PUZZLES
This book is the result of twenty years of puzzle collecting. For
these many years I have endeavored to gather everything
belonging to the realm of mathematical entertainment from
all available sources. As an editor of newspaper columns on
scientific entertainment, I found my readers keenly interested
in this kind of pastime, and these readers proved to be among
my best sources for all sorts of problems, both elementary
and intricate.
Puzzles seem to have beguiled men in every civilization, and
the staples of scientific entertainment are certain historic problems
which have perplexed and diverted men for centuries.
Besides a number of these, this book contains many problems
never before published. Indeed, the majority of the problems
have been devised by me or have been developed out of
suggestions from readers or friends.
This book represents only a relatively small selection from
an inexhaustible reservoir of material. Its purpose is to satisfy
not only mathematically educated and gifted readers but also
those who are on less good terms with mathematics but consider
cudgeling their brains a useful pastime. Many puzzles are
therefore included, especially in the first chapters, which do
not require even a pencil for their solution, let alone algebraic
formulas. The majority of the problems chosen, however, will
appeal to the puzzle lover who has not yet forgotten the elements
of arithmetic he learned in high school. And finally,
those who really enjoy the beauties of mathematics will find
plenty of problems to rack their brains and test their knowledge
and ingenuity in such chapters as, for example, "Whimsical
Numbers" and "Playing with Squares
