About Mentalc

Mentalc is a simple mental math game for practicing addition, subtraction, multiplication, and division. Change the digit length and question count for arithmetic practice, calculation training, math drills, or brain training.

How to Use

Choose the digit length, operation, and number of questions, then start. Enter answers with the on-screen keypad or your keyboard. A correct answer moves to the next question automatically, and the result screen shows your time and history.

Practice Tips

Start with a small set of one-digit addition questions. As you get comfortable, increase the digit length or add multiplication. Use your recent records to reduce time gradually while keeping your answers accurate.

Recommended practice order

Start with one-digit addition and subtraction until you can answer accurately. Then move to two-digit problems, multiplication, division, and percentages so your mental math practice grows step by step.
