Multifunctional electronic abacus for mental abacus calculation study training

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 connect
