How practice works
Pick a setup and start solving.
Mental Math Trainer lets users choose the operation, session pressure, and number range before each run. The app presents timed questions, locks each submitted answer, gives immediate feedback, and summarizes performance at the end.
Demo question
38 + 47 = 85
Classic session: 10 questions, 10 seconds each.
Built from the app
Training options match the Android experience.
Timed questions
Each question has a visible countdown, immediate correct or incorrect feedback, and automatic timeout handling.
Difficulty levels
Easy, Medium, and Hard adjust number ranges and templates so sessions can feel light, focused, or intense.
Best score
The app keeps a local best score and shows session accuracy, total time, wrong answers, mode, and challenge.
