The International Mathematical Olympiad (IMO) is a very important
competition for high school students. China has taken part in the IMO 31
times since 1985 and has won the top ranking for countries 19 times,
with a multitude of gold medals for individual students. The six
students China has sent every year were selected from 60 students among
approximately 300 students who took part in the annual China
Mathematical Competition during the winter months.This book includes the
problems and solutions of the most important mathematical competitions
from 2010 to 2014 in China, such as China Mathematical Competition,
China Mathematical Olympiad, China Girls' Mathematical Olympiad. These
problems are almost exclusively created by the experts who are engaged
in mathematical competition teaching and researching. Some of the
solutions are from national training team and national team members,
their wonderful solutions being the feature of this book. This book is
useful to mathematics fans, middle school students engaged in
mathematical competition, coaches in mathematics teaching and teachers
setting up math elective courses.
