Button type abacus mental arithmetic device and realizing method thereof

Abstract

The invention relates to button type abacus calculating device. It includes frame, beam used to divide the frame into upper and lower areas, and may buttons. The abacus bead is distributed in the upper and lower areas. Each button can be switched between the set and the clear states. Each line of the four buttons in the lower area has linkage relation to make pressing the button have the same effect with stirring abacus bead. This device is convenient for memory, easy to image, good for culturing children interesting. In addition, it is not easy to stir wrong while using, can be hung or used in car ship etc bumpy environment.

Description

technical field [0001] The invention relates to a computing device with intelligence development and computing functions, in particular, the invention relates to an abacus mental arithmetic device. Background technique [0002] Abacus mental arithmetic is the abbreviation of abacus-style mental arithmetic. It is a calculation method that turns numbers into abacus symbols and floats in the brain, and performs addition, subtraction, multiplication, and division operations based on the abacus principle. The characteristic of abacus mental arithmetic is the ingenious combination of traditional Chinese abacus calculation method and image memory. The calculation result can be obtained by imagining the abacus. Learning abacus is a good way to develop intellectual potential. For children whose brains are still in the period of rapid development, learning abacus and mental arithmetic can not only develop the right brain and improve the ability of image thinking, but also make the br...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the beads are elliptical or rhombus-shaped, when several adjacent columns of beads form a set of data, the overall image is not conducive to memory due to the unevenness of the border

[0006] 2. In the stage of empty dialing and wanting to dial, it is easy to make mistakes when imagining the second, third, and fourth beading, because the four consecutive beadings are exactly the same, and it is not easy to think clearly if you dial one more or one less.

[0007] 3. When transitioning from real dialing to air dialing, frequent switching is required, which is not convenient enough

And children who are the main users of this kind of abacus and mental abacus are often active by nature, lack patience and self-learning ability, so they are easily bored by frequent switching, which affects their interest in learning

[0008] 4. Generally, it should be placed horizontally when used. It is not convenient to be used as a teaching aid for hanging, and it is not convenient to use in bumpy environments such as vehicles and ships.

[0009] 5. Because the contact surface between fingers and beads is not large, it is easy to make mistakes

For example, when dialing up and down beads continuously (such as dialing "two up, five into one", or "three down, five down to two"), the fingers should first be positioned on the upper bead and the lower bead to be moved, and then determine the upper bead and the lower bead. In which direction to move the lower bead, and finally move the bead to the correct position, and the adjacent bead may pass by in the process of toggling, resulting in misallocation
