Abstract
Apparatus for teaching mathematics has numerical and mathematical operational inputs by way of coded cards placed in respective card readers and a keypad that produces number values and numerical equations. The number values and equation results are compared to the numeric value of weight objects placed on a scale by the student. The apparatus is bi-directional in that unit weights are placed on the scale to attempt to match the numeric values and the equation solution values produced by the cards and keypad or the cards and keypad entries for numerical values and equations are made to match the numeric value of the unit weight objects on the scale. The student is informed of the result of the comparison in terms of correct or incorrect, or by explanatory messages to either increase or decrease the unit weight value or change the number value or the equation.
