## Description

MathCalc is a comprehensive mathematical tool designed for students, educators, and anyone interested in combinatorics. The application provides fast and accurate calculations for permutations and combinations, along with an interactive quiz mode to test your understanding.<br><br>Key Features:<br><br>• Permutation Calculator: Quickly calculate P(n,r) values with the formula P(n,r) = n! / (n-r)!<br><br>• Combination Calculator: Compute C(n,r) values using C(n,r) = n! / (r! × (n-r)!)<br><br>• Random Quiz Mode: Test your knowledge with randomly generated permutation and combination problems. Track your score and improve your skills.<br><br>• Formula Reference: Access detailed explanations of factorial, permutation, combination formulas, and binomial theorem with examples.<br><br>• Privacy Focused: No personal data collection. All calculations performed locally on your device. Only requires internet permission to display privacy policy.<br><br>• Offline Functionality: All core features work without internet connection. No account registration required.
