About Mental Math Duel
Mental Math Duel turns everyday arithmetic into short, focused play sessions. Addition, subtraction, multiplication and exact division appear one calculation at a time. Work out the answer and enter it with your keyboard or the on-screen number pad. Every answer is a nonnegative whole number. In Duel mode, a visible pace rival gives each round its rhythm. Answer correctly before the rival reaches the finish to earn the point. Each duel has 12 rounds and three difficulty levels; Easy uses addition and subtraction. The rival follows a fixed visible pace and never reads your answer. The Daily Challenge gives everyone the same 20 calculations for a particular UTC date. You have 90 seconds, with one point for each correct answer. For a calmer session, Practice removes the clock and offers hints. Progress is saved on your device, so you can return to an unfinished game. Assisted and restored runs remain separate from competition. You can switch among 11 languages during play and adjust the sound or motion settings.
