Abstract
Abstract A teaching machine, on a given number of depressions of a first button, which makes a distinct sound with each depression, lights that number of lamps in a first 3 by 3 matrix in a given order to show the groups of 1''s, 2''s, and/or 3''s which make up that given number. A second button, on each depression, unlights a single lamp to show subtraction. A second 3 by 3 matrix of lamps has one lamp light after all lamps are lit in the first matrix on depression of the first button which then turns off the bulbs of the first matrix. This second matrix shows the decimal concept of number from ten up. Numerical indicators show the numbers represented. Arrows pointing between the matrixes show the addition of nine plus one moving from the first units matrix to the second tens matrix or the subtraction of ten minus one moving from the second tens matrix to the first units matrix. A square overlay divided into three zones is placed over at least the first units matrix with the zones in a horizontal or a vertical position to selectively indicate different groupings of lamps making up a given indicated number. Specific circuitry is used so that each additional lamp in a matrix which is lit lights all the other required bulbs to indicate a given number.
