Abstract

The invention relates to a multifunctional electronic abacus for learning and training abacus mental arithmetic, which comprises a processor circuit and a button circuit, the button circuit is connected with the input end of the processor circuit; the button circuit includes five rows of abacus buttons and a memory Each column of the five rows of bead buttons corresponds one by one, wherein the first row of abacus buttons is located above the recording point, and the four rows of abacus buttons are located below the recording point; the five rows of abacus buttons Each bead button in the bead is connected in series with a corresponding light-emitting diode; the state of the light-emitting diode can be changed after the bead button is pressed; all the light-emitting diodes are respectively connected to the function conversion button through the bead display button and the wire, and the function The switch button is connected to the power supply terminal; the function switch button is used to select one of the wires and pearl display buttons to connect to the power supply terminal. The invention can not only improve the operation speed of the abacus mental arithmetic, but also can proofread the appearance of the abacus without using cards.

Description

Technical field [0001] The invention relates to a teaching tool, in particular to a multifunctional electronic abacus used for abacus mental arithmetic learning and training. Background technique [0002] Abacus mental arithmetic, referred to as abacus mental arithmetic. It has great potential in improving computing speed, developing intelligence and promoting the development of non-intellectual factors. According to statistics from the China Abacus Mental Arithmetic Association, from the 1980s to June 2010, 46 countries and regions around the world have carried out abacus mental arithmetic education, of which 4.2 million people in my country have learned abacus mental arithmetic. Therefore, conducting research on abacus mental arithmetic algorithms and reforming and innovating abacus mental arithmetic teaching aids and learning tools to improve learners' abacus mental arithmetic operations can not only produce better social benefits, but also produce better economic benefits. ...
