发明名称 Mathematical learning tables
摘要 The present invention comprises a teaching aid for increasing the probability of learning the results of a mathematical operation consisting of a series of tables containing mathematical facts based on mathematical operations performed on a subset of whole numbers. Each successive table displays a decreasing subset of the mathematical facts, which encourages the student to learn said facts based on the mathematical operation involved.
