ARITHMETICAL
AND ALGEBRAICAL PROBLEMS.
"And what was he?
Forsooth, a great arithmetician."
Othello, I. i.
The puzzles in this department are roughly thrown together in classes for the
convenience of the reader. Some are very easy, others quite difficult. But they
are not arranged in any order of difficulty—and this is intentional, for it is
well that the solver should not be warned that a puzzle is just what it seems to
be. It may, therefore, prove to be quite as simple as it looks, or it may
contain some pitfall into which, through want of care or over-confidence, we may
stumble.
Also, the arithmetical and algebraical puzzles are not separated in the
manner adopted by some authors, who arbitrarily require certain problems to be
solved by one method or the other. The reader is left to make his own choice and
determine which puzzles are capable of being solved by him on purely
arithmetical lines.
