Method and apparatus for educating mathematical functions
First Claim
1. A method comprising the steps of:
- providing a plurality of first numerical sequences, each numeral within each of said first numerical sequence being identified by a common indicia and each of the plurality of first numerical sequences having different indicia;
providing a second numerical sequence of numerals;
providing a third numerical sequence, each numeral in the third numerical sequence having an indicia corresponding to the common and different indicia of the first numerical sequence;
wherein each of the numerals of the plurality of the first, second and third numerical sequences is arranged as respective radial segments in concentric circles, each concentric circle having the common indicia and wherein each numeral differs by a whole integer and at least two radial segments of the numerical sequences are in abutting relationship;
aligning a selected numeral from each of the second and third numerical sequences whereby when the numeral of the first numerical sequence is a mathematical function of the numerals of the second and third numerical sequences the indicia of the third sequence is the same as the indicia of the first sequence.

Abstract
An apparatus comprises a first plurality of first numerical sequences, each numeral within each first numerical sequence being identified by a common indicia and each of the plurality of first numerical sequences having a different indicia; a second numerical sequence of numerals; and a selector which is relatively movable with respect to the first and second numerical sequences for selecting one numeral of the second sequence of numerals. The selector has third numerical sequence wherein each numeral of the third sequence has an indicia which corresponds to the common and different indicia of the first numerical sequence. The common and different indicia is color or pattern selective. In the method, the numeral of the first numerical sequence is a mathematical function of the numerals of the second and third numerical sequences.

9. An apparatus comprising:
-
a first means for indicating a plurality of first numerical sequences, each numeral within each first numerical sequence being identified by a common indicia and each of the plurality of first numerical sequences having different indicia; a second means for indicating a second numerical sequence of numerals; a selector means relatively movable with respect to the first and second means for selecting one numeral of the second sequence of numerals, the selector means having a third numerical sequence, each numeral in the third numerical sequence having an indicia corresponding to the common and different indicia of the first numerical sequence; wherein each of the numerals of the plurality of the first, second and third numerical sequences is arranged as respective radial segments in concentric circles, each concentric circle having the common indicia and wherein each numeral differs by a whole integer and at least two radial segments of the numerical sequences are in abutting relationship; whereby when the numeral of the first numerical sequence is a mathematical function of the numerals of the second and third numerical sequences the indicia of the third sequence is the same as the indicia of the first sequence. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
