From the developer:
NumberExplosion offers a simple and fun way to practice your multiplication tables. In this game you select a difficulty level that corresponds to the maximum multiplier of random equations falling from the sky. You will target an equation by entering its product using the game's numeric key pad. If you are correct, a missile will be launched which will explode the targeted equation upon impact, earning you points equal to its product.
