Math Sprint

How to play

1. Answer each sum as fast as you can: right answers score 10 × level plus a streak bonus.
2. Type the answer on the keypad or your keyboard; it is sent when all its digits are in (or press Enter). For answers below zero press − first.
3. Every 5 right answers is a level up: addition and subtraction first, then ×, ÷, two-step sums and answers below zero.
4. Sprint 60 ends when the minute is up; Survival gives you three hearts (wrong answer or time out costs one) and less time per question.
5. Practice: choose + − × ÷ or two-step problems and a range up to 10, 20 or 100, with no clock; press the flag to finish.
6. With Choice, tap one of the four answers or press 1-4 (half the base points).
7. After each run, check your accuracy, pace and the sums you missed; your run is saved, so you can Continue later.
