**This section contains many difficult
puzzles that can be used to motivate advanced students. Many of the puzzles
are distinct and require different levels of student mathematical abilities
ranging from elementary algebra to number theory and beyond. Although most
are not within the scope of a normal high school student's mathematical
ability, these puzzles are quite brief and understandable. Very often, they
will lead to the investigation of other interesting topics in mathematics.
However, some explanation by the teacher may be necessary to enhance the
understanding and appreciation of the puzzle by the students.** |
