Abstract
The utility model relates to a numerical double-bead abacus which is composed of a calculational frame, a number distribution frame and a number recording frame, wherein, beads in the number distribution frame and the number recording frame are marked with ten arabic numbers from 0 to 9. Every block in the calculational frame is only provided with two beads and every two blocks can represent a numerical position. The utility model has the advantages of visual calculation, simple calculation, difficult bead carry, etc., is a calculational tool which can be used generally, and is particularly suitable for learning calculation with an abacus for pupils.
Description
The utility model relates to a kind of digital Shuangzi Abacus for calculation.
At present, normally used abacus has two kinds, and a kind of is the five pearl selfish calculations of the band decorative pearl on top of an official cap and end pearl, and the big abacus of seven pearls is traditional Abacus for calculation, it is fast that it has computing velocity, characteristics such as easy to use, but its computing method especially the computing method mouth of division is certainly various, difficult note is hard to understand, difficult grasp, and owing in every grade five to seven pearls are arranged, easy belt when dialling abacus makes result of calculation mistake occur.The decorative pearl on top of an official cap and the end pearl in the big abacus of seven pearls removed in five pearl selfish calculations, and its computing method and seven rechoning by the abacus dishes are basic identical.
The purpose of this utility model is to provide a kind of calculating easy, is difficult for the abacus of belt.
The utility model is according to the principle of plus-minus, multiplication and division written calculation, whole abacus is designed to cloth counts frame (1), numeration frame (2) and (5) three frames of calculation block, cloth is counted to design in the frame (1) 5～9 perpendicular shelves (7), two beads (6) are arranged on every grade, every beads is marked with 0 to 90 arabic numeral, during numeration, beads is dialled from put the beams in place (3), required numeral is turned to topmost, and design has a crosspiece in the numeration frame (2).6～10 beads (6) are arranged on the crosspiece, also indicate 0 to 90 arabic numeral on every beads.In the calculation block (5), design has 12～20 perpendicular shelves (7), per two grades is that the upper left pearl of each numerical digit of numerical digit is represented " 5 ", upper right pearl is represented " 2 ", two following pearls represent that all " 1 " can represent 1～9 nine numeral with four beads in each numerical digit, if 4 beads all leave underbeam (4), then " 0 " is represented in this room.
When calculating plus-minus method, summand or minuend and addend or subtrahend are dialled in cloth count in the frame, during calculating numerical digit is aimed at, calculate and in calculation block, carry out, when calculating multiplication, multiplicand and multiplier are dialled in cloth is counted frame,, in calculation block, calculated according to the principle of taking advantage of from a high position, when calculating division, dividend is dialled in the calculation block, and divisor is dialled in cloth and is counted in the frame, calculates by division written calculation rule.Each total that calculates gained is dialled in the numeration frame, so that checking computations.
Owing to adopted technique scheme, the utlity model has and calculate intuitively, there is not never belt of the mouth of calculating, result of calculation characteristics such as be difficult for makeing mistakes can be used as a kind of computational tool to use, and are specially adapted to the pupil and learn rechoning by the abacus.
Accompanying drawing is that master of the present utility model looks synoptic diagram
Be embodiment of the present utility model below
Embodiment one: carry out additional calculation.Add 293 as 1679 and dial in 1679 on row's beads on earlier in cloth is counted frame, dial 293 on the following row's beads in cloth is counted frame again, numerical digit is alignd, in calculation block, calculate then.Dial last 1, hundred last 6 on the kilobit and add 2 and equal 8, groups 8, ten last 7 add 9 and equal 16, " 1 " in " 16 " is dialled on hundred, and dial on ten " 6 ", and individual position last 9 adds 3 and equals 12, " 1 " in " 12 " is dialled on ten, and dial on individual position " 2 ", promptly gets and be 1972.
Embodiment two: carry out multiplication and calculate.Dialling 679 as 679 * 93 first numbers on the frame at cloth on row's beads, dial 93 on the following row's beads in cloth is counted frame again, aligns with " 6 " of multiplicand in " 9 " of multiplication.During calculating, take advantage of from seniority.6 take advantage of 9 to get 54, dial 54 in calculation block; 7 take advantage of 9 63,6 be added on 4, move right again one and dial 3; 9 take advantage of 9 81,8 be added on 3, move right again one and dial 1, multiply by 679 o'clock with 3, the number of gained moves right after one and the 9 long-pending additions of taking advantage of 679 gained again, can obtain that to amass be 63147.
Embodiment three: carry out division calculation.As 1376 divided by 32, in calculation block, dial 1376 earlier, again in cloth is counted frame groups 32, during calculating, press division written calculation rule, get three figure places earlier promptly 137 divided by 32, can discuss 4, on 4 groups of first beads in the numeration frame, 32 multiply by 4 gets 128, deduct 128 with 137, get remainder 9, use 96 then, can discuss 3 divided by 32, with 3 groups on second beads of numeration in the frame, get promptly that to discuss be 43.
Claims (3)
1, a kind of digital Shuangzi Abacus for calculation is made up of framework, beam, pearl and shelves, it is characterized in that with whole abacus be divided into calculation block (5), cloth is counted frame (1) and (2) three parts of frame that count, and is marked with arabic numeral on the pearl (6) that is used to calculate and count.
2, digital Shuangzi Abacus for calculation according to claim 1 is characterized in that having only two beads (6) on calculation block and cloth are counted each shelves in the frame, on every beads in cloth is counted frame and numeration frame, indicates 0～90 arabic numeral.
