Abstract
'A binary measuring implement and a binary counting frame' show the manner of displaying the existence and the calculation of the quantity by combinations of different binary units, in combination with the manner of displaying the existence and the reading-writing and calculation of the quantity by combinations of different decimal units and the manner of displaying the existence and the reading-writing and calculation of the quantity by combinations of same units in the patent 200610095300.8, the three manners are called three algorithms in mathematics, when a unit value is equal to a position value, a decimal number, a binary number and a natural number are mutually rewritten, and the rewriting shows the change of a quantity formation structure. The decimal number is beneficial to reading and writing the displayed quantity, the binary number is beneficial to calculation of the quantity, and the natural number is beneficial to announcing the increase or decrease of the quantity and the relation of two quantities (simple comparison and ratio). Based on combination of the three algorithms, the mathematics education can be simple, scientific and sustainable, and can keep pace with the times.
Description
Technical field:
The present invention shows a kind of new teaching instrument: with the amount of different binary units making
Tool and abstract calculation tool.
Background technology:
The mankind are the three R'ss that assembly (natural number) with same units goes to show quantity since ancient times: 2006100953008 patents show the three R's that goes to show quantity with the assembly (decimal number) of different decimal units.The present invention is the three R's that the assembly (binary number) with different binary units goes to show quantity.Decimal number, binary number and natural mutual rewriting; Show the change of a quantity composition structure; Decimal number is beneficial to the read-write of quantity, and binary number is beneficial to science and calculates, and natural number is beneficial to the most contacts of measuring and the relation of two quantity of showing; Their integrated application, make that mathematical education is simple, science, sustainable, grow with each passing hour.
Summary of the invention:
The present invention only provides with the assembly of different scale-of-two long measures and shows the measurer of length and abstract calculation tool.
For realizing above-mentioned purpose, the present invention adopts following technology to realize:
The scale-of-two gage: on the rule that shows 1cm (degree of accuracy of base unit, metering), each scale place all shows with 1, from first left " 1 ", below 1, marks respectively: 2

When ten thousand, thousand, hundred, ten, individual; Pearl and usefulness about in the of every grade; Can show respectively that numeration mark 1,2,3,4,5,6,7,8,9 has different separately positional value (French famous mathematician Laplce) at diverse location, shows the literary style of nature.Annotate: ten thousand, thousand, hundred, ten, one, be the pronunciation of diverse location value.(... Multifarious a hundred or so is sequence of positions, is not number bit sequence)

Embodiment
See Fig. 1, understanding scale-of-two gage, the representation of paying attention to unit promptly: show its meaning with mathematical model (being line segment) here; Show its existence with 1; With its sign (title, symbol, unit value ...) express, the importance of unit sign, both can the amount of showing different classes of; Can show not commensurate big and little of amount of the same race again, here not the sign of commensurate with separately unit value (power) expression.
1, on rule, gesticulate, impression is experienced not commensurate of scale-of-two: 2
0(showing 1cm), 2
1(showing 2cm), 2
2(showing 4cm), 2
3(showing 8cm), 2
4(showing 16cm)
2, being familiar with the base unit that this chi makes is 1cm, is expressed as 2 on the chi
0
3, metering and expression
1. just be certain scale-of-two long measure as if the length that records a thing, as: 2
0=1,2
1=2,2
2=4,2
