Embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
A kind of calculating, registration demonstration device, comprise mainboard 1, loose seed 7 and frame three parts; Mainboard 1 is provided with loose seed 7 and puts position, and frame is positioned at the avris position of mainboard, and frame has the both direction limit, Yi Bian be provided with loose seed 7, puts the expression numerical value of position, and another side is provided with the expression place value that loose seed pendulum 7 is put position.
5 one-tenth vertical arrangement modes of frame of the expression place value that frame 4 and the loose seed that loose seed 7 is put the expression numerical value of position put, the expression numerical value that loose seed 7 is put position apart from vertical intersection point more far more greatly or more far less, the expression place value that loose seed is put position apart from vertical intersection point more far more greatly or more far less.On frame, to put the expression numerical value of position be one, two, four, six and eight to loose seed 7, and the expression place value that on frame, loose seed is put position is divided into, ten, hundred, thousand and ten thousand.
Mainboard is rectangle sheet metal, plank or plastic plate, the wooden or plastics of periphery.Mainboard is provided with 5 gear positions, 25 holes, and each gear has five to be used for putting hole figure or the matrix hole of calculating seed.Horizontal or vertical 3 positions, matrix hole, middle part are provided with the indications 3 that indicates 3 positions, matrix hole, middle part.Loose seed is oval plastic sphere.
Frame is two groups of minute up and down, every group of frame consists of the frame of the expression place value that the frame of several expression numerical value of loose seed being put to position and loose seed are put, two groups of frames are arranged on mainboard by rivet clasp bolt 6, the rivet clasp bolt adopts the rivet-like of wooden or plastics, the length of rivet is determined according to the thickness of four lateral frame boards and mainboard, leaves the space that can allow frame rotate freely.Frame can be around the rotation of rivet clasp bolt, selecting type and mainboard coupling.
The present embodiment adopts same interface, and along with the conversion of frame content, the numerical value shown in same hole changes; Represented registration orientation also changes, and derives eight operating surfaces; Formed natural sequence extends by the upper and lower, left and right four direction.Can realize demonstrating out the functions such as different calculating, registration in 99999 digital scopes.
The present embodiment changing location calculates and the explanation of multinomial registration:
Changing location calculates
Calculate same exercise question, by " rivet clasp bolt ", rotate arbitrarily a frame and overlap with mainboard, obtained a frame condition, according to the frame condition that this coincidence position, limit provides, calculate, calculating process has formed the calculation seed running orbit of this frame condition.Rotate again a frame and overlap with mainboard, the frame condition of having got back, calculating process can form again other calculation seed running orbit.In like manner, can form eight kinds of different running orbits.
The operation rule of the present embodiment and illustrating:
(1) this grade operation rule
In computation process, put and calculate the rule that seed must be followed " abandoning few, the enough position occupy-place of multiselect ".For example, 2 add 4, can not put two and calculate seed, and enough 6 position must represent with a form of calculating seed; Same 8-2 can not show with 4 and 2 form.Follow this rule, every grade of all computation processes and result of calculation thereof can not exceed two with the seed amount and calculate seeds.
(2) illustrate
Example: 2+4-3=3
Figure 10 represent 2, Figure 11 represent+4, Figure 12 represents-3 and result 3.
In like manner: Figure 13 represent 2, Figure 14 represent+4, Figure 15 represents-3 and result 3.
2. multinomial registration
1---in 99999 natural sequences, filter out the numeral that meets the octahedral demonstration, multiply the different registration intension of octahedral.The hole of same numerical value, by the different position, limit of conversion, can express different numerical value.
Example: Figure 16 is extremely shown in Figure 23 is exactly eight different interfaces that 28 these numbers are multiplied.
In like manner, if by the change of the frame content of upper figure, in this eight width figure, from the number shown in two VOID POSITIONS of the first width figure " 28 ", by from left to right order, be respectively: 28,82000,61,86000,2001,6008,10020,80060.
The present embodiment has described simple in structure, draws materials conveniently, and method is easy, understandable, flexible, and is interesting strong; Temper notice, memory, observation, the power to think; Strengthen number sense ability, distinguish the actively effect such as azimuthal capability.
