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

These are real attempts in a browser — every device, every connection, first tries included. Published research figures are usually collected on dedicated hardware with practiced participants under controlled conditions, so they typically run higher than what this table shows. Both are useful, and they answer different questions: a score can sit well behind the research figure and still be mid-pack among people actually taking the test here.
