Math Speed Test
How many can you get right in 60 seconds? Mixed +, −, × and ÷ with typed answers. No signup, works on any phone.
How the test works
- You get 60 seconds, or 2 minutes if you choose the longer test, and one question at a time, with addition, subtraction, multiplication and division mixed together.
- Type the answer. A right answer moves on by itself, so you never need to press Enter. Enter, or OK on the keypad, submits what you have typed: that is how a wrong answer is recorded.
- Your score is the number you get right. A wrong answer takes nothing away, but it costs time.
- The clock never stops. Switching tabs keeps it running, and the button in the top-left corner ends the test early.
- Your best score is kept in this browser, separately for each length, level, set of operations and way of answering.
The questions
At the Classic level, which the test starts on:
- Addition: two numbers from 2 to 100, such as 58 + 67.
- Subtraction: the same sums backwards, such as 125 − 67, so an answer is never negative.
- Multiplication: a number from 2 to 12 times one from 2 to 100, such as 8 × 47.
- Division: the same products backwards, such as 376 ÷ 8, so it always comes out whole.
Settings change the level: Kids keeps to adding numbers up to 10 and times tables up to 10 × 10, and Hard moves to three-digit sums and two-digit times two-digit products. Change one thing at a time, or your scores stop being comparable.
Getting a better score
Accuracy first. A wrong answer scores nothing and still uses up the seconds you spent on it, so a careful answer beats a fast guess. Once your answers are reliably right, speed comes from taking fewer steps, not from thinking faster.
1. Know the times tables cold
Half the questions are multiplication or division, and every one of them uses a number from 2 to 12. If 7 × 8 still needs a moment, that moment is where your score goes.
84 ÷ 7
- ask: 7 times what is 84?
- 7 × 12 = 84
= 12
2. Split the big number
Multiply the tens, then the units, and add the two. Say the first product to yourself so you only have one number to hold while you work out the second.
8 × 47
- 8 × 40 = 320
- 8 × 7 = 56
- 320 + 56
= 376
3. Divide in chunks
Take away a round multiple of the divisor first, then see what is left. Two easy steps are quicker than one long division done in your head.
252 ÷ 6
- 6 × 40 = 240
- 12 left, and 6 × 2 = 12
- 40 + 2
= 42
4. Subtract a round number
When the number you take away ends in 7, 8 or 9, take away the next ten instead and give the difference back.
143 − 68
- 143 − 70 = 73
- that took 2 too many, so add 2 back
= 75
Questions people ask
What is a good score?
There is no single number worth comparing against. The length, the level, the operations, and whether you type on a keyboard or tap a keypad all move the score a lot. Compare with yourself instead: keep the same settings, take the test a few times a week, and watch your best, which shows under the Play button.
How do I get faster at mental math?
Short, regular tests do more than one long session. Notice which questions make you hesitate, usually a handful of times-table facts, and work on those. Practice has no clock, so you can take your time over them.
One minute or two?
One minute is a quick check. Two minutes evens out a slow start or one hard question, so it is the better one to track over time.
Is this like Zetamac?
It works the same way: you type the answer, a right answer moves on by itself, and subtraction and division are addition and multiplication run backwards. If you are used to two-minute rounds, choose 2 minutes.
Can a class take it together?
Yes. Each student opens this page on their own device; there is nothing to sign up for, and settings and best scores stay in each browser. For younger students, choose the Kids level in Settings first.
Does it work on a phone?
Yes. On a touch screen a number pad appears at the bottom, so the phone's keyboard never covers the question. On a laptop, type with the keyboard.
Practice without the clock
Practice asks the same kinds of questions with no timer at all, and the main trainer plays Survival, where health drains and right answers win it back. The main trainer also explains six techniques that turn hard questions into easy ones, worth learning before you come back to the test.
