Mental Math Test

Solve arithmetic problems as fast as you can. Add, subtract, and multiply your way through as many as you can in 60 seconds — the cleanest measure of your mental math speed.

You'll see one problem at a time. Type the answer using your numeric keypad — the next problem appears the moment your answer matches.

How It Works

  1. Click Start. The 60-second timer begins immediately and the first arithmetic problem appears.
  2. Type the answer. Use the numeric keypad. The next problem auto-advances the moment your typed answer matches — no Enter required.
  3. Wrong answers cost time, not points. If you mistype, just clear it and try again. There's no penalty beyond the seconds you lose.
  4. Score = correct answers in 60 seconds. Elite performers clear 40+. Most untrained adults land between 15–25.
