Getting your game ready…
Solve ten additions, subtractions or multiplications. Each correct first attempt earns ten points. There is no time limit.
Choose one of four answers, or press 1, 2, 3 or 4. After an incorrect answer, you can retry, but that question will not earn points.
Break larger calculations into smaller ones. For example, 8 × 7 can be thought of as 8 × 5 plus 8 × 2.
