Foundations

How to play

Start practicing to receive a short set of addition, subtraction, multiplication, division and mixed-arithmetic problems. Work through the set one answer at a time. This mode starts a solo session, so you can concentrate on your own calculations without waiting for an opponent.

Practice and points

Correct answers move you forward and earn activity points based on problem difficulty. Incorrect answers can be retried without losing activity points or being eliminated. Use the session to warm up, check a calculation method or revisit arithmetic facts that need more practice.

Guests and accounts

Example problem

36 ÷ 6 = 6

Think of the related multiplication fact: 6 × 6 = 36. Multiplication and division facts can help you check each other.
