Nintendo's "Personal Trainer" series continues with Personal Trainer: Math, a collection of 40 fast-paced exercises designed to make arithmetic easier and more enjoyable. The game makes use of "The Hundred Cell Calculation Method" that places numbers in a 10 x 10 grid, and the exercises are similar to many "brain training" games in that they are intended to be played quickly and repeatedly. The games begin with simple addition and subtraction but eventually move on to more difficult calculations, and players can earn medals as rewards for their success. ~ Christopher Brown, All Game Guide
