Math Fast Plus and Minus is an Android math practice app that focuses on basic arithmetic. You can play addition, subtraction, or a mix of both, and the app covers elementary-level lessons.
Practice modes and difficulty
The app lets you choose which operations to practice: addition only, subtraction only, or both together. Difficulty levels can be customized, and game rules such as the minimum and maximum numbers used in questions can be set to suit a particular skill level.
Answer input and time limits
The description notes that several input types are available for entering answers. Time limits can also be set, which allows a short warm-up round or a more demanding timed session.
Review and progress tracking
After each game, the app lets you check answers to see which ones were wrong. Statistics can be viewed at any time to follow progress across sessions.
