➗ Mental Math Sprint: 60 Seconds of Arithmetic

💡 How to play — You have 60 seconds to solve as many mental arithmetic problems as you can, picking the right answer from four options. Correct answers are worth more as the problems get harder, and a streak of three or more multiplies every point you earn. A wrong answer breaks the streak and takes three seconds off the clock, so guessing is expensive. The problems shift from simple sums to two-digit work and multiplication as the clock runs down.
