Multifunctional electronic abacus for mental abacus calculation study training

Abstract

The invention relates to a multifunctional electronic abacus for mental abacus calculation study training. The multifunctional electronic abacus for mental abacus calculation study training comprises a processor circuit and a key circuit. The key circuit is connected with the input end of the processor circuit and comprises five rows of abacus bead keys and position marking points. The abacus bead keys correspond to one other in each row. One row of abacus bead keys are located above the position marking points and the other four rows of abacus bead keys are located below the position marking points. Each abacus bead key of the five rows of abacus bead keys is connected with a corresponding light-emitting diode in series. After one abacus bead key is pressed down, the state of the corresponding light-emitting diode can be changed. All the light-emitting diodes are connected with function transformation keys through lighting bead display keys and leads respectively. The function transformation keys are connected with a power source end and used for selecting one path from the leads and the lighting bead display keys to be connected with the power source end. According to the multifunctional electronic abacus for mental abacus calculation study training, the arithmetic speed of mental abacus calculation can be improved and mental abacus presentation can be corrected by a user under the condition that cards are not used.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a multifunctional electronic abacus used for learning and training abacus and mental arithmetic. Background technique [0002] Abacus mental arithmetic, referred to as abacus mental arithmetic. It has great potential in increasing computing speed, developing intelligence and promoting the development of non-intellectual factors. According to statistics from the China Abacus and Mental Arithmetic Association, from the 1980s to June 2010, a total of 46 countries and regions around the world have carried out abacus-style mental arithmetic education, of which 4.2 million people in my country have learned abacus-style mental arithmetic. Therefore, the research on the calculation algorithm of abacus mental arithmetic and the reform and innovation of abacus mental arithmetic teaching aids and learning tools to improve the level of learners' abacus mental arithmetic operations can not only produce bet...
