How-to, tips & answers

Practise mental maths in short rounds, with a timer or at your own pace.

How it works

  1. Choose a difficulty, question count and optional time limit.
  2. Enter and check each answer.
  3. Review your result and any incorrect answers at the end.

Set up a round

Choose from three difficulty levels and 5, 10, 20 or 50 questions. Add a time limit if you want one. Easy starts with addition and subtraction without negative results; higher levels add multiplication and division. Divisions have whole-number answers.

Learn from mistakes

Each answer gets immediate feedback. The result shows how many you got right and the questions you missed. Progress summarises recent practice.

Good to know

What happens when the time runs out?

The round ends. Unanswered questions do not count as correct. Choose no time limit if you prefer to take your time.
