SUMMARY OF THE INVENTIONThe present invention is directed toward a multiplication calculator wherein, in accordance with a first embodiment of the present invention, there is provided a multiplication calculator which comprises a substantially cylindrical platform having a plurality of rotatable wheels which are mounted upon an axle such that the plurality of rotatable wheels are rotatable around a longitudinal axis defined by the axle such that the plurality of rotatable wheels are capable of being moved or rotated in a stepwise manner, and wherein all of the wheels are located within adjacent planes with respect to each other. All of the wheels have a plurality of steps or facets, such as, for example, ten steps or facets, defined thereon, and the first wheel has multiplicands noted upon each step or facet ranging from zero (0) to nine (9). In addition, there are an additional nine (9) wheels, which effectively contain the multipliers or answers noted upon their steps or facets. More particularly, these additional wheels contain numbers which extend from zero (0) to eighteen (18) in increments of two upon the second wheel, numbers which extend from zero (0) to twenty-seven (27) in increments of three upon the third wheel, numbers which extend from zero (0) to thirty-six (36) in increments of four upon the fourth wheel, numbers which extend from zero (0) to forty-five (45) in increments of five upon the fifth wheel, numbers which extend from zero (0) to fifty-four (54) in increments of six upon the sixth wheel, numbers which extend from zero (0) to sixty-three (63) in increments of seven upon the seventh wheel, numbers which extend from zero (0) to seventy-two (72) in increments of eight upon the eighth wheel, numbers which extend from zero (0) to eighty-one (81) in increments of nine upon the ninth wheel, and numbers which extend from zero (0) to ninety (90) in increments of ten upon the tenth wheel.
A plurality of windows are provided within a linear array extending across the calculator such that when you rotate a particular one of the multiplier wheels in accordance with a particular number of steps or partial rotations, and in accordance with a particularly selected multiplier, the answer will appear within that particular window operatively associated with the particular wheel that was rotated. In use, let us take as an example, the multiplication problem of 3×7. Therefore, one would locate the three (3) upon the first wheel, since three (3) is the multiplicand, then move horizontally across the array of wheels, within the row of the number three (3) multiplicand, until one comes to the seventh wheel, then rotate the seventh wheel three steps, corresponding to the multiplicand, and the answer of twenty-one (21) will appear within the window, operatively associated with the seventh wheel, disclosing the answer to the multiplication problem.
In accordance with a second embodiment of the present invention, the structure of the second embodiment is somewhat similar to that of the first embodiment except that in lieu of rotatable wheels, all of the multiplicands and answers are noted upon the plurality of steps or facets defined upon a solid block wherein, in a manner similar to that of the first embodiment, the numbers are arranged in adjacent columns which extend around the external periphery of the solid block, as well as in adjacent rows which extend across the solid block. In use, and using the same example of multiplying 3×7, one would again locate the three (3) within the first column, and then move laterally across the solid block, within the row of the multiplicand three (3), to the seventh column where the numerical answer of twenty-one (21) will be located.
Various other features and attendant advantages of the present invention will be more fully appreciated from the following detailed description when considered in connection with the accompanying drawings in which like reference characters designate like or corresponding parts throughout the several views, and wherein:
Referring now to the drawings, and more particularly to
In addition, a plurality of windows 126-144 are provided within a linear array that extends across the calculator 100 such that each window 126-144 is respectively associated with one of the rotatable wheels 102-120. The linear array of windows 126-144 may all be mounted upon a framework 146 which, in turn, may be fixedly secured to a non-rotatable portion of a housing structure 148 through which the axle 122 extends. Accordingly, when a particular one of the wheels 104-120 is rotated in accordance with a particular number of steps or partial rotations, in accordance with a particular multiplier being used to multiply a particular one of the multiplicands noted upon the first wheel 102, the answer will appear within the particular window operatively associated with the particular one of the wheels 104-120 that was rotated.
Exemplary Use of the First EmbodimentIn order to clearly demonstrate the use of the first embodiment of the mathematical calculator 100 of the present invention, let us take as an example, the multiplication problem of 3×7. Therefore, using the mathematical calculator 100, one would locate the three (3) upon the first wheel 102, since three (3) is the multiplicand, then move horizontally across the array of wheels 104-120, while remaining within the same row as the multiplicand three (3) is located, until one comes to the seventh wheel 114, then rotate the seventh wheel 114 three steps, corresponding to the multiplicand, whereby such rotation will bring the particular facet 124, upon which the number twenty-one (21) appears, into the window 138, thereby clearly presenting the answer of twenty-one (21) to the multiplication problem. As previously noted, the use and manipulation of the mathematical calculator in accordance with the foregoing principles and teachings, will help people, particularly, young children, to learn their multiplication tables or to help such children confidently master multiplication problems.
Continuing further, a second embodiment of the present invention is disclosed within
Therefore, in a manner similar to that of the first embodiment of the mathematical calculator 100 of the present invention, in order to clearly demonstrate the use of the second embodiment of the mathematical calculator 200 of the present invention, let us take the same example that we used in conjunction with the first embodiment of the mathematical calculator 100 of the present invention, that is, the multiplication problem of 3×7. Therefore, using the mathematical calculator 200, one would locate the three (3) within the first column 202, since three (3) is the multiplicand, then move horizontally across the array of facets 224, while remaining within the row containing the multiplicand three (3), until one comes to the seventh column 214, whereby the answer of twenty-one (21) to the multiplication problem is clearly presented. As previously noted, the use and manipulation of the mathematical calculator in accordance with the foregoing principles and teachings, will help people, particularly, young children, to learn their multiplication tables or to help such children confidently master multiplication problems.
Obviously, many variations and modifications of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described herein.
