![]() ![]() One user inappropriately compared the students’ hand motions to a debilitating disease, while another joked that the young mathematicians could surely eliminate computers in the future. The reaction on Weibo was seemingly mixed. ![]() The counting method calls for the use of one’s fingers and mind for fast counting. This Video is about a technique in which you can use your fingers to calculate really fast, It Is called chisanbop, Finger mathematics or Finger abacus but. Shakespeare and the Visualization of Metaphor in Two Chinese Versions of. Watch a roomful of students shake out the answers to math problems below (VPN off):Ī similar math calculation technique was invented by the late Shi Fengshou, a professor at the University of Science and Technology of China. Gold Jewellery Rings Pendants Chains Bangles Biscuit Fish Abacus And Ohm Ring. The novel counting method helped students achieve as many as 219 correct answers out of 222 questions in the demanding 15-minute arithmetic competition. Multiplication can be done by mentally multiplying the digits and adding up the intermediate. The teacher noted that students of a higher level can simply solve an equation without the use of this hand-waving technique, while others need a boost of ‘brain power.’ He added that the lower the student’s level, the faster they need to move their hand. Over the centuries both the Japanese and the Chinese have developed and used many different techniques for solving problems of multiplication on the abacus. The basic operations of the abacus are addition and subtraction. Multiplication techniques on the Chinese Suan Pan, the 'Extra Bead ' and the 'Suspended Bead' (contributed by Francis Wong and Totton Heffelfinger) The Suan Pan, or Chinese abacus, was in use in China for three or four centuries before making its journey to Japan sometime in the 1600s. Its a wooden rack with metal rods with beads attached to them. Chinese students have a global reputation for being quick-witted when it comes to mathematics, but do you know why? Perhaps a recent event in Northwest China may help shed some light on their impressive math skills.Īt a math competition recently held in Lanzhou, Gansu province, a total of 245 students were seen using an unusual technique to answer questions: Hand waving.Ī school instructor told the Paper that students who use their left hand in combination with their computing skills (the key factor, we’d like to add) can quickly solve math equations. Abacus was invented by the Chinese around 4000 years ago.
