When time runs out, see your score, accuracy percentage, and CPM (correct per minute). Challenge yourself to improve each round.
Q: What is CPM?
A: CPM stands for Correct Per Minute — the number of problems you solved correctly divided by the time in minutes. It's a standardized speed metric like WPM for typing.
Q: Can I use keyboard input?
A: Yes! On desktop, you can type answers with your keyboard number keys and press Enter to submit. On mobile, tap the on-screen number pad.
Q: Is this suitable for kids?
A: Absolutely. The Beginner level uses single-digit addition only, making it perfect for elementary students learning arithmetic. Parents and teachers can use it for daily practice.
