Test yourself on the number system with a maths quiz from your notes
Upload your lesson slides, PDF or notes and get multiple-choice, true/false or short-answer questions on bases, place value and number sets, each with an explanation.
How a number system quiz helps you practice
Number system topics such as place value, bases, and rational and irrational numbers are easy to nod along to in class and harder to recall under exam pressure. A maths quiz on the number system built from your own lesson notes makes you retrieve the rules yourself, which is the part that makes them stick.
- Multiple-choice, true/false and short-answer formats
- Explanations that show the working behind each answer
- Questions drawn only from the material you upload
- Free to start, with no credit card required
Questions from your own material
Upload a PDF, slides, DOCX, plain notes or a photo of a page, and get questions on the number system taken from that lesson.
Explanations for every answer
Each question comes with a short explanation, so a wrong answer shows you what to review instead of just marking it wrong.

How it works
Upload your notes
Add a PDF, DOCX, PPTX, text file or a photo of your number system lesson.
Choose the question type
Pick multiple-choice, true/false or short-answer questions for the quiz.
Answer and review
Work through the questions and read the explanation after each one before moving on.
Work through questions on binary and hexadecimal conversion, number sets and place value, then read the explanation for every answer you miss. Repeat the questions that caught you out a day or two later so the gaps close before the test.

Frequently asked questions
How do I practice converting between binary, octal and hexadecimal?
Convert a few decimal numbers to each base by repeated division, then convert them back to check your answers. Practice the hexadecimal digits A to F until you recognize them without counting, since they appear in most exam questions.
What is the difference between rational and irrational numbers?
A rational number can be written as a fraction of two integers with a non-zero denominator, such as 3/4 or -2. An irrational number cannot, and its decimal expansion neither terminates nor repeats, as with the square root of 2.
Can I export my quiz to another tool?
Yes, exports are part of the paid plans. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML export.
