Math quiz in 30 seconds

This free math quiz gives you timed arithmetic questions — addition, subtraction, multiplication, division, percentages, and powers & roots — at three levels. You get instant right-or-wrong feedback on every answer, a score out of the total, your time per question, and a review table at the end so you can see exactly where marks were lost.

How to take the quiz

  1. Choose an operation (or Mixed for all four) and a level: Easy, Medium or Hard.
  2. Pick 10 or 20 questions, and how many seconds each question allows.
  3. Press “Start quiz”, type each answer, and press Enter or the Answer button.
  4. When the time bar runs out, the question counts as missed and the quiz moves on.
  5. Read your score and the review table, then play again to beat it.

Teachers use timed quizzes like this as a warm-up: put it on the projector in fullscreen, and the whole class races the same clock. At home, one short quiz a day is a friendly way to keep mental math fast.

What each level asks

Every question is generated fresh, inside fixed ranges, so no two quizzes are the same and answers always come out as whole numbers — division questions are built backwards from the answer, so they always divide evenly.

Question ranges by level

MediumNumbers up to 100Tables up to 12 × 9From tables up to 12
HardNumbers up to 1,000One number up to 99 × 6 to 9Answers up to 25, divisors 3 to 12

A good target: on Medium, a fluent student answers most questions in under 10 seconds each. On Easy, under 5 seconds a question means the basic facts are becoming automatic — that is the point of practice. Speed matters less than the trend: your average time per question is shown after every quiz, so you can watch it fall week by week.

Why timed practice works

  • Retrieval beats re-reading. Answering a question from memory strengthens it far more than looking at a worked example again.
  • The clock adds focus. A gentle time limit stops drifting and makes ten questions feel like a game against yourself.
  • The review shows the gaps. If every miss is a borrowing subtraction or the 7 times table, you know exactly what to practice next — try the multiplication chart for tables.
  • Short and daily wins. Ten questions take about three minutes. A small daily habit beats one long session, because the brain keeps what it revisits.

Frequently asked questions

How does the math quiz work?

You pick an operation, a level, and how many questions you want. Each question is timed. Type your answer and press Enter — you find out right away whether it was correct, and at the end you get a score, your total time, and a review of every question.

Is this math quiz free?

Yes, it is completely free, with no sign-up, no account and nothing to install. Play as many quizzes as you like.

What levels are there, and who are they for?

Easy uses small numbers and tables up to 5, good for younger children and warm-ups. Medium goes to 100 and tables up to 12. Hard reaches 1,000, bigger multiplications and division answers up to 25 — a real challenge for older students and adults.

What happens if the time runs out on a question?

The question is marked as missed, the correct answer is shown, and the quiz moves to the next question. You can also choose “No limit” in the settings if you prefer to practice without a clock.

Are the division questions always whole numbers?

Yes. Division questions are built from the answer backwards, so they always divide evenly and the correct answer is a whole number. The same care is taken with subtraction, which never asks for a negative answer.

Does the quiz include percentages and powers?

Yes. The Percentage option asks questions like “What is 20% of 150?”, and Powers & Roots asks squares, square roots and small powers like 7², √81 and 2⁵. Every answer is a whole number, and both topics also turn up in Mixed quizzes.

Can I see which questions I got wrong?

Yes. The results screen has a review table listing every question, your answer, the correct answer, whether you were right, and how long you took. It is the fastest way to spot a weak spot.

Can a teacher use this quiz in a classroom?

Yes. Open it on a projector or smartboard, press Fullscreen, and read the questions aloud while the class writes answers, or let students take turns at the board. The settings link can be copied and shared so everyone starts with the same setup.

Does the quiz save my best score?

Your best percentage for each operation and level is saved in your own browser, and shown on the setup screen. Nothing is sent to a server, and clearing your browser data clears the saved bests.

Are two quizzes ever the same?

Almost never. Questions are generated fresh for every quiz from your browser’s random source, inside the ranges for the level you picked, so each run is a new set of questions.

How can I get better at mental math?

Take one short quiz every day and watch your average time per question. When one operation keeps costing you marks, practice it on its own for a few days — and use CalcNova’s calculators, like the fractions calculator, to check your homework method, not just the answer.
