Timepiece with multiplication table display and method of teaching multiplication tables

A method of performing multiplication, comprising the steps of:

• dividing a face of a timepiece into a central region and a circumferential region;
• selecting a first multiplier N, wherein N is an integer between one and twelve;
• displaying the first multiplier N in the central region;
• dividing the circumferential region into N annular portions;
• displaying a set of integers xN(y) about each of the N annular portions of the circumferential region, wherein y is an integer ranging between one and twelve such that x1(1) to x1(12) ranges between one and twelve to simulate a face of an analog timepiece, and XN(y)=X1(y)+(N−1)×12;
• displaying at least a simulated hour hand and a simulated minute hand;
• positioning the simulated hour hand and the simulated minute hand with respect to an innermost annular portion of the circumferential region to indicate the present time;
• selecting a second multiplier M, wherein M is an integer between one and twelve;
• identifying the second multiplier M in the N=1 annular portion of the circumferential region;
• making a sequence of clockwise steps from the second multiplier M to the value of xN(y) equaling N×M, wherein if the product of N×M is greater than twelve, the sequence of clockwise steps follows a clockwise path to each multiple of twelve within a respective one of the N annular portions and continues into the next higher annular portion, the number of the clockwise steps being given by (N−1)×M.

A kit of timepieces with multiplication table displays, comprising a set of twelve timepieces, each of the timepieces having:

• a face divided into a central region and a circumferential region, each the timepiece having an integer value N between one and twelve displayed in the central region of the face thereof, wherein N represents a first multiplier, each the face having a circumferential region divided into N annular portions, a set of integers xN(y) respectively being displayed about each of the N annular portions of each of the circumferential regions, wherein y is an integer ranging between one and twelve such that x1(1) to x1(12) ranges between one and twelve, and xN(y)=x1(y)+(N−1)×12;
• an hour hand;
• a minute hand;
• and
• means for positioning the hour hand and the minute hand with respect to an innermost annular portion of the circumferential region to indicate the present time;
• whereby, the user selects a second multiplier M, wherein M is an integer between one and twelve, and identifies the second multiplier M in the N=1 annular portion of the circumferential region, such that the user then may make a sequence of clockwise steps from the second multiplier M to the value of xN(y) equaling N×M, wherein if the product of N×M is greater than twelve, the sequence of clockwise steps follows a clockwise path to each multiple of twelve within a respective one of the N annular portions and continues into the next higher annular portion, the number of the clockwise steps being given by (N−1)×M.
