Mathematical Olympiads 1998–1999

This volume contains a large range of problems, with and without solutions, taken from 25 national and regional mathematics olympiads from around the world, and the problems are drawn from several years' contests. In many cases, more than one solution is given to a single problem in order to highlight different problem-solving strategies. The collection is intended as practice for students preparing for these competitions. Teachers and general readers looking for interesting problems will find also it very useful.

• Challenging problems
• Detailed solutions to half the problems
• Often several solutions to one problem to compare different problem-solving strategies
