About this app

Explore math concepts and practice their linked problems in MathTap. Submit an answer to see the correct answer and solution. Revisit problems you missed in your review notes. Try up to 5 sample problems before signing in.

Explore how to solve
When a hint is available, explore the ideas behind the problem. Some hints also include examples.

Check your answer and the solution
After submitting, compare your answer with the correct answer and check the result. If a solution is available, follow its steps and compare them with your own approach.

Find a concept to practice
Browse concept explanations and open their linked practice. Check the next problem based on your learning history and review status, or choose practice by topic.

Return to problems you missed
Sign in to review saved answers and the solutions shown at the time. Try a problem again while it remains available. Find review records by concept, date and other filters.

Keep your own answer and working
Choose or enter an answer as the problem requires. If there is a working field, you can also write down your approach. Feedback on your working varies by problem.

See when and what you practiced
View answer counts, accuracy, learning dates and practice records by unit. Accuracy is calculated from graded answers only. You can also check badges and notification settings in the app.

Find a starting point
Start with a short assessment: an initial set of 10 problems across 10 areas, followed by additional problems when needed. It guides your next practice based on those answers; it does not determine your grade level or overall mathematical ability.

Use Korean or English
Choose Korean or English in Settings. You can view learning content in your chosen language when a translation is available. Earlier answers and learning records stay in their original language.
