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. Some subtractions go negative: use the ± button.

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. For negative answers (some subtractions), tap the ± button next to the input.
- 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.
Understanding Your Score
| Correct in 60s | Rating |
|---|---|
| 40+ | Elite |
| 25–39 | Fast |
| 15–24 | Average |
| Under 15 | Below Average |
The score is a fluency measure. Most problems here are single-step arithmetic — small sums, differences, and times-table products — so the test rewards how quickly an answer comes to mind, not whether you can eventually work it out. High scorers recognize answers by recall where slower scorers compute them digit by digit, and because the test auto-advances on a correct answer, typing the result in one motion matters as much as knowing it. Input device counts too: a physical numeric keypad is measurably faster than a phone keyboard, so compare your best runs on the same setup.
Tips for Improvement
- Drill times tables and number pairs that sum to 10 or 20 — most problems resolve by recall once these are automatic.
- For two-digit sums, work left to right (tens first, then ones) — it matches how the answer is typed.
- Miss one? Clear the input and re-enter immediately rather than second-guessing digit by digit — hesitation costs more than the retype.
- Use a physical numeric keypad if you can; the test is best experienced on desktop with a keyboard.

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.
