About this game

Fast Math is a math problem-solving game where you solve problems by "writing" numbers on the screen with your finger or a pen. There's no need to press the keypad; it feels like doing math on paper, but you get the result instantly when you finish writing.

Each round has 12 questions, timed from the first to the last. The goal isn't just to answer correctly. But the goal is to improve your time compared to the last round.

【5 Game Modes】
• Addition
• Subtraction — No negative results
• Multiplication
• Division — Always exact division, no remainder
• Mixed — Alternate all four modes in one round

【4 Difficulty Levels】
• Beginner — Addition and subtraction up to 9, multiplication and division using multiplication tables 1 to 5. Suitable for children just starting out.
• Medium — Addition and subtraction up to 20, multiplication and division up to 10.
• Advanced — Addition and subtraction up to 60, multiplication and division up to 12.
• Hard — Addition and subtraction up to 199, multiplication and division up to 20.

【Handwriting Answers】
Write your answer directly on the screen. Supports multi-digit numbers such as 13 or 108. After writing, pause for a moment, and the system will check it automatically. If correct, move to the next question immediately.

Handwriting recognition works entirely on your device; your handwriting is not sent to any server.

If your device doesn't support handwriting recognition, the game will automatically switch to the numeric keypad. Therefore, it can be played on all devices. And you can switch back to handwriting practice.

【See Your Progress】
At the end of each round, you'll see the time taken for each question, the total time, and a graph comparing it to previous rounds. Statistics are kept separate by mode and difficulty level, so you can see which mothers are still slowing down.

【Who is this game for?】
• Elementary school children who are practicing mental arithmetic and multiplication tables.
• Parents who want their children to practice math without interruptions from ads.
• Adults who want to sharpen their minds for a few minutes each day.

【What's Not in This Game?】
• No ads.
• No in-app purchases.
• No registration or login required.
• No personal data collected. All statistics are stored only on your device.

Upon first launch, an internet connection is required for a short time to download the handwriting recognition system. After that, you can play offline indefinitely.
