Math Sprint gives you 20 arithmetic questions and measures how fast you can answer them correctly. Addition, subtraction, multiplication, and division questions appear one at a time and your total time is recorded when you finish. The challenge is accuracy under speed pressure, because a wrong answer adds a time penalty.
Mental math speed is a genuine skill that improves with practice. Most people are fastest at simple addition and slowest at division by larger numbers. Playing Math Sprint regularly builds the number pattern recognition that makes mental arithmetic feel automatic rather than effortful. It is also just a satisfying challenge to try to beat your own time from the previous round.
