Want longer practice? Mental Arithmetic adapts its level to you, and the five-minute routine shows how to build a habit around it.
Questions
When does a new challenge start?
Every day at 00:00 UTC. Everyone who plays on the same UTC day gets the same ten questions in the same order.
How is the score counted?
Your score is the number of correct answers out of ten. The time shown is only the time questions were on screen, so the short pause after each answer is not counted.
Do I need an account?
No. Your result and daily streak are stored in this browser. Clearing site data or switching devices starts the streak again.
What kind of questions are there?
Addition and subtraction warm-ups, then multiplication, division, a percentage and two-step expressions. Every answer is a whole positive number.
