How math trivia questions get made from your notes

Good math trivia tests recall of facts and ideas, not just arithmetic, so the questions need to come from a source that contains those facts. A chapter on number theory or a set of geometry slides gives you the material to write questions about primes, angles and proofs that someone actually learned.

Questions are written from the pages or slides you upload, not from a generic question bank.
Each multiple-choice, true/false or open question includes an explanation of the answer.
Photos of textbook pages are read with text recognition, so handwritten-free printed pages work well.
The free plan includes 3 generations per month and browser study; exports need Plus or Pro.

Example math trivia questions with answers

Is 1 a prime number?No. A prime has exactly two distinct positive divisors, and 1 has only one.

What is the only even prime number?2. Every other even number is divisible by 2, so it has at least three positive divisors.

Does 0.999... repeating equal 1?Yes. Multiply 0.333... by 3 to get 0.999..., and 1/3 times 3 equals 1.

What comes next in the sequence 1, 1, 2, 3, 5, 8?13. Each term in the Fibonacci sequence is the sum of the two terms before it.

What do the interior angles of any triangle add up to?180 degrees. Drawing a line parallel to one side through the opposite vertex shows the three angles form a straight line.

Frequently asked questions

What makes a good math trivia question?

A good question has one clear correct answer and tests a specific fact or idea, such as a property of primes or the sum of angles in a triangle. Questions that depend on a single memorable concept are easier to check and explain than long word problems.

How can I make math trivia more challenging?

Use open-ended or short-answer questions instead of true/false, and include material from more advanced chapters. Reviewing the explanations after each attempt helps you spot the ideas you still mix up.

Can I export the quiz to PDF or DOCX?

Yes, PDF and DOCX export is included with Plus, which costs $39/year or $7.99/month. Pro at $14.99/month adds QTI 2.1 and Moodle XML export.

No. You can start on the free plan with 3 generations per month and study in the browser without adding a credit card.
