Название: My Best Puzzles in Mathematics
Автор: Phillips H.
There is little that I need say by way of introduction to this
collection of puzzles. They are all strictly "mathematical,"
though the mathematical knowledge necessary for solving
them is, in all but a handful of cases, elementary. That is
because these puzzles have all been published serially in
various newspapers and magazines, and their appeal would be
negligible if their solution demanded advanced mathematics.
They appear here, with their original wording unchanged,
except that, where puzzles involve monetary calculations,
I have converted pounds, shillings, and pennies into dollars
and cents. The factual basis of many of these puzzles is derived
from various games, e.g., contract bridge. A good many are
based on Britain's national game: association football
("soccer"). You don't need to know this game to tackle the
puzzles based on it. Its scoring is simplicity itself: each side,
if it scores at all, merely scores one, two, or more goals.
