Mental Arithmetic - Math

Mental Arithmetic — a portable mental math training system. Build fundamentals, break through weak spots, and see your progress clearly.

SYSTEMATIC PRACTICE
• Addition, subtraction, multiplication, and division
• Integers, decimals, and fractions
• Four difficulty levels; adjustable question count and time limit
• Dynamic questions—start a basic session anytime

FOCUSED TRAINING
• Weak-spot diagnosis: pinpoint structural gaps (borrowing, carrying, times tables, and more)
• Technique dojo: make-ten, complement multiply, distributive law, and more—learn the method, then practice
• Rhythm flow: train steady speed, not frantic rushing
• Number-sense estimation: magnitude estimates and quick comparisons (correct within tolerance)

DAILY DIAGNOSIS
A short, auto-planned session based on your weak areas and due reviews—a clear reason to open the app every day.

PROGRESS YOU CAN SEE
• Skill mastery map across micro-skills
• Statistics: accuracy, speed, recent volume, and long-term trends
• Practice calendar with monthly comparisons to build a lasting habit

For students building foundations, adults rebuilding fluency, and anyone who wants mental math that is faster, steadier, and clearer.
