Numericalvaue is a professional iOS application for mathematics education, specifically designed for learning and demonstrating mathematical set operations. Adopting a unique striped fabric style interface design, providing an intuitive and aesthetically pleasing user experience.
The core functions include collection creation and management, where users can customize collection names and add any element. It supports multi set operations, allowing the same element to appear multiple times in the collection. The application has implemented complete set operation functions: union , intersection , difference , complement , and subset relation judgment.
In terms of visualization, the application provides Venn diagram display and list view, supporting interactive element selection and detailed information display. Users can define a complete set for complement operations and support element index access. The application has data persistence function, and the collected data is automatically saved between application sessions. The application is developed based on Swift and provides powerful tool support for mathematics learning and teaching.
