KEY FEATURES

• Fast-Paced Timed Rounds
Quick arithmetic sprints you can complete anywhere—during your morning commute, between classes, or on a short break. Rounds range from 6 to 12 focused challenges depending on difficulty, keeping intensity high without causing mental fatigue.

• Custom Zero-Latency Keypad
Standard mobile keyboards slide up, shift your layout, and cause input delay. Mental Math features a built-in, tactile numerical keypad designed specifically for rapid calculation under time pressure with instant touch feedback.

• 3 Balanced Difficulty Levels
• Easy (6 questions, 30s per question): Essential addition and subtraction up to 20, times tables up to 10×10, and clean exact division. Perfect for daily warm-ups and arithmetic confidence.
• Medium (10 questions, 25s per question): Larger numbers up to 30, multiplication tables up to 12×12, and compound 3-term equations combining addition, subtraction, and multiplication.
• Hard (12 questions, 20s per question): Multi-step arithmetic with parentheses, operator precedence, and 3-to-4 term equations. Every question is algorithmically designed to produce clean, positive whole numbers—no negative answers and no guessing decimal rounding.

• In-Depth Round Analytics & History
Consistent mental math progress requires real data. Review your calculation performance after every game:
• Average response time and accuracy percentage
• Time spent on every individual problem in the round
• Breakdown of operations to see where you gained or lost pace
• Personal best records tracked separately for Easy, Medium, and Hard
• Full local game history stored privately on your device
