How to play
Goal. Practise quick mental arithmetic: score as many right answers as you can in 60 seconds, or work through a times table at your own pace.
60-second sprint
- Pick one or more operations (+, −, ×, ÷) and a level, then press Start. The clock starts at once.
- Easy uses numbers up to 10 and small times tables, Medium goes up to 50 and the 12 times table, Hard uses numbers up to 250 and larger factors.
- Answers are always whole numbers that are zero or more. A right answer counts as soon as you finish typing it; a wrong one needs Enter and shows the right answer.
Times tables
- Choose a table from 2 to 12, or Mixed for twelve facts from all of them. Every fact from × 1 to × 12 comes up once, in a shuffled order.
- There is no clock. A missed fact returns once at the end, and the summary lists any facts worth revising.
| Question | Answer | Result |
|---|---|---|
| 7 × 8 | 54 | Slip: 56 |
| 7 × 3 | 21 | Right |
| … | … | … |
| 7 × 8 | 56 | Right, asked again |
Tips
- Split hard sums: 47 + 38 is 47 + 40 − 2. For subtraction, count up from the smaller number.
- Every division is a times table backwards: 56 ÷ 7 asks which number times 7 makes 56.
- Learn the tricky facts in pairs: if 6 × 8 = 48, then 8 × 6 = 48, 48 ÷ 6 = 8 and 48 ÷ 8 = 6.
