How to play

Sign in to see your progress and preview the next problem type. The selection comes from nearby unfinished skills in curriculum order. Each run starts with easy problems and adapts its difficulty to your answers during that session. Your saved skill progress is tracked separately.

Guides, hints and reveals

The first guided turns display a solution guide. Later, use the available hints and reveals when you need help, and earn extra help through correct-answer streaks. Incorrect answers do not eliminate you. Sessions end when you reach the session rating target or the question limit, so the focus stays on learning rather than survival.

Account required

An account is required to play Explorer because it uses and saves your individual learning progress. You can read this introduction without signing in. Choose Foundations for guest arithmetic practice, or Progression for a broader adaptive practice session.

Example problem

x + 7 = 12 → x = 5

Subtract 7 from both sides to isolate x: 12 − 7 = 5. Guided practice helps connect a worked method with the next problem you solve yourself.
