Q: Why do you need to be aware of mathematical quickies and trickies?

A: They often appear in math contests and competitions to trick the novice problem solvers—they act as a filter to sieve the nerd from the herd.

Moreover, mathematical quickies and trickies often humble the mathematically proud—that no smart student can totally avoid conventional thinking in getting the incorrect [often intuitive] answer.

Target audience (Grade 5 and above)

• Above-average students
• Home-schooled students
• Mathletes and Coaches
• Creative tutors
• Talented or gifted students
• Students bored by school Math
• Self-motivated tutees
• Christian or mission schools
• Coaches of mathletes

What are Quickies and Trickies?

• Questions teachers shy away because they are hard to crack if improperly approached. Conventional methods are seldom necessary to solve them; most are rather tackled in a common-sense and logical approach.
• Questions or variations commonly set in IQ and aptitude tests to trap the unwary. They are what teachers called the “Tricky Questions.”
• Questions which may be solved by a bright 8-year-old, yet defeat the average mathematics teacher and educated parent.
• Questions which defy intuition, frequently posed in math contests and examination papers to frustrate the rote learner and catch the mathematically-challenged.
• Questions which the obvious solution is never the correct one. What offhand appears to be true is false.
• Quickies and Trickies will not only enhance your problem-solving skills, but also help you to be more careful in approaching unorthodox mathematics questions.
• At the end of it, the solutions of many of these non-routine questions will make them appear predictable, rather than challenging. What may, at first, appear challenging will, in the end, become routine.
• All that you need is a little knowledge of elementary school mathematics, open- mindedness, and persistence to participate in the delights of Quickies and Trickies.
