Challenges in Math

In China, we know very well what the contest problems for various levels are in the U.S., since they are often published in a lot of Chinese periodicals. It is quite hard to believe that there are only a few or even no mathematical contest problems of other countries in numerous (math) educational magazines here in the United States. Frankly speaking, the American math competition problems look much easier in comparison with those of China. So, I think it is worthwhile to introduce some Chinese math competition problems to the American teachers and parents. The problems compiled here are from the second round of the Chinese Primary School Mathematics Examination 1987 (for 5th and 6th graders). It is a 14-question, 90-minute examination.
