MathMind gives students in Armenia the complete worked solution to every problem in the official mathematics workbooks (shtemaran) used to prepare for the national unified exams — not just the final answer. Find any problem by its four numbers — part / chapter / section / problem — and the app opens the full solution: the statement exactly as printed in the workbook, every step with an explanation of why it is taken, all sub-questions solved separately, the drawings where the problem has them, and the verified answer. Mathematical notation is typeset properly, the way it looks on paper. WHAT IS IN A SOLUTION • The problem statement, complete, in the workbook's own wording • The steps with explanations — the why, not only the what • Every sub-question (a, b, c) worked out separately • Geometric drawings rendered inside the solution • The checked answer, on the same screen HOW SEARCH WORKS Enter four numbers — part, chapter, section, problem — and tap search. For example, 1/2/3/4 opens problem 4 of section 3, chapter 2, part 1 together with all of its sub-questions. SUBSCRIPTION Access is sold as a non-renewing subscription for 1, 3 or 6 months. Nothing renews automatically and nothing is charged again when the term runs out: the purchase adds days to your account and you decide whether to add more. Every plan gives the same access to all solutions, with a limit of 30 problem lookups per day. Access belongs to your MathMind account, so signing in on another device brings it back. The app's interface and all solutions are in Armenian. Questions: support@mathmind.am

Verdict
