_{4}SMP Negeri 3 Tambang, obtained an average value ability of understanding mathematical students in the classical style on the first cycle is higher than the average value on first tests ability of understanding mathematical students and the average value ability of understanding mathematical students classically on the second cycle is higher than the average value in first cycle. Average value ability of understanding mathematical students classical students has increased from the first tests to the first cycle of 13.89. The average value ability of understanding mathematical students classical has increased from the first cycle to the second cycle at 5.46.
