關於本電子書

Singapore’s bestselling Mathematical Quickies & Trickies, which has sold over 90,000 copies locally, contains more than 300 nonroutine problems to enhance students’ mathematical problem-solving skills. With many creative worked examples and questions, and with cartoons sprinkled throughout the book, Mathematical Quickies & Trickies would appeal primarily to these audiences:

* grades 5-7 students and teachers looking for some fertile trick and tricky questions;

* mathletes preparing for local and regional contests and competitions;

* problem solvers longing to be challenged by questions whose obvious solutions are never the correct ones for what offhand appears to be true is false.

With proper insight, you’ll learn how to solve these tricky problems almost instantly, whose solutions are almost never the correct ones. You need no longer be caught off-guard; instead, you’ll learn to solve these questions confidently—how to tame these counter-intuitive questions into routine ones.
