The results of the 16th Hua Cup finals are urgent

<> Participants: Primary schools.

Students in the fifth and sixth grades, and students in the first year of junior high school.

National Finals: Generally held in Guangdong Province in July every year, because the finals are too late, it has little effect on the small promotion. Contest Features:

Subjective questions are set, and the preliminary competition before the 11th session will be assessed in the form of live TV, and the test papers will be answered from the 11th session.

Introduction: Hua Luogeng Gold Cup Juvenile Mathematics Invitational Contest (hereinafter referred to as "Hua Cup") is to commemorate China's outstanding mathematician Professor Hua Luogeng, founded in 1986 the National Cavity Large-scale Juvenile Mathematics Competition, which was jointly sponsored by China Juvenile Daily (now China Juvenile News Press), China Optimization Method, Overall Planning Method and Economic Mathematics Research Association, ** TV Youth Center and other units. The Hua Cup is the largest, most formal and most difficult competition at the primary school stage in China.

The first Hua Cup was awarded to the Great Hall of the People, and its authority can be seen! But what is more embarrassing is that due to the difficulty of the Hua Cup, the number of people entering the semi-finals and finals is small, and from the perspective of small promotion, the reference range of the Hua Cup is relatively small. Therefore, many parents now feel that the Hua Cup has little effect on the junior high school, but in fact, this is definitely a misunderstanding.

Winning the Hua Cup has a very big effect on the junior high school, but it is more difficult to win the award and the number of people is smaller. So in fact, as long as your child is strong enough in Olympiad, the Hua Cup will be the best way for him to prove his Olympiad ability.

Judging from the scores of previous editions, 80 points in the 2016 Hua Cup should be able to enter the semi-finals.
