This app offers various math quizzes to challenge your brain. It includes sections for calculating the angles of plane figures, determining the areas of plane figures, and solving number sequence puzzles. The app progresses from basic problems to more difficult ones, providing a comprehensive mental workout.
Key features include the ability to calculate angles and areas of various plane figures, solve number sequence problems, and progress through multiple difficulty stages. Users can also write calculation memos directly on the screen, receive hints for challenging problems, and share problem images with friends via SNS or email.
The app is free to download and use, but it does offer in-app purchases. Specifically, an 'ad removal' purchase is recommended for users aged 12 and under, and for devices used by organizations like schools or cram schools. This suggests the free version may contain advertisements.
The app features problems focused on geometry, such as finding the angles and areas of different plane figures. It also includes number sequence puzzles where you need to determine the missing number. The problems are designed to range from basic to advanced difficulty levels.
The math problems were created with the cooperation of university students who are graduates of prestigious high schools like Nada, Koyo, Tsukukoma, and Kaisei. This indicates a high level of academic rigor and accuracy in the problem design.
