Correlating strongly with Nintendo's Brain Age and Big Brain Academy games, Personal Trainer: Math seeks to improve basic math abilities with fun and rewarding games. Personal Trainer: Math features the Hundred-Cell Method pioneered by the in-game host, Hideo Kageyama. This method requires players to do back-to-back, fast-paced arithmetic problems, including addition, subtraction, multiplication, and division. Starting with a 10x10 grid, with numbers populated along the top and left sides, players will need to perform the specified function and fill in the corresponding grid space. The exercise continues until all of the one hundred cells are filled.
