Mental Math

1. 1Each set has ten short calculations. Type the answer in your head, then check it.
2. 2There is no countdown, and a wrong answer costs nothing: it shows you the right one and you move on. You can also skip a question.
3. 3Easy is simple adding, taking away and small times tables. Medium goes up to bigger numbers and the full times tables. Hard has two-digit products, percentages and squares.
4. 4There is a new set every day, the same for everyone, gentle most days and harder on Saturdays. The timer is optional and never counts for XP.

Type your answer and press Enter to check it, then Enter again for the next question.
