Mental Math

Mental Math is a browser arithmetic game that challenges you to solve math problems as quickly and accurately as possible. Choose from addition, subtraction, multiplication, division, or mixed operations, then pick between 60-second Sprint mode or three-life Survival mode. Every correct answer raises your score and builds your streak, while wrong answers cost precious time or lives. The game scales question difficulty as you play, starting with simple single-digit problems and advancing to harder multi-step arithmetic. Your average response time, longest streak, accuracy percentage, and personal best score are tracked every session and saved locally so you can beat your own records on later attempts. The on-screen chalk-style keypad makes touch and mobile play seamless, while keyboard users can type answers directly with number keys, backspace, and enter. A warm chalkboard visual theme with green board textures, chalk-yellow accents, and particle effects for correct answers creates a focused classroom atmosphere. Results after each game show a full breakdown of your performance including score, speed, accuracy, best streak, and whether you set a new personal best. With instant replay, you can jump back in immediately to improve your numbers.
