Intriguing math teasers for ages 11 up, brilliantly answered. -
This excellent collection of teasers has inferential problems in
arithmetic and algebra, and includes geometry, mazes, magic squares
and a lot of chess-board tours. The answers are often gems in
themselves -- things mentioned in passing and left to the reader to
establish -- e.g. ... of the twelve ways that eight queens can be
placed on a chessboard without attacking one another...
At twelve years old I spent many an hour finding those twelve
ways. I still find challenges in it in spite of my Masters degree
in Mathematical Physics
With 430 puzzles, problems, paradoxes, and brain teasers, this
book is a mammoth puzzle collection, compared with most math
teasers and puzzles book available. But what is important is not
the quantity, but the quality and charm of the problems presented.
Each problem is presented with a full length solutions that makes
the book absolutely an instructive experience for the reader. In
some cases the author even discussed on how others had attacked and
failed the problems.
You, your freinds and family will spend many hours trying the
vast array of puzzles prented in this book.
