Why generate math flashcards from your own PDF

Printable sets of math problems rarely match the chapter your class is on, which is why a math flashcards PDF from your own material is more useful than a download. Your instructor's notation, your textbook's theorem names and the examples your teacher worked in class are what show up on the test.

Upload a chapter PDF and get flashcards tied to its definitions and worked examples.
Use spaced repetition in the browser so formulas you struggle with return more often.
Export to PDF, DOCX, Anki or CSV on Plus, which costs $99.90 per year or $9.99 per month.
Students get 40% off with a school email, and no credit card is needed to start.

Example algebra flashcards from a PDF unit

What is the quadratic formula?x = (−b ± √(b² − 4ac)) / 2a, which solves ax² + bx + c = 0 for x.

What does the Pythagorean theorem state?In a right triangle, a² + b² = c², where c is the hypotenuse, the side opposite the right angle.

What is the slope of a line through (x1, y1) and (x2, y2)?(y2 − y1) / (x2 − x1), the change in y over the change in x, provided x2 is not equal to x1.

What is the derivative of sin(x)?cos(x). The derivative of cos(x) is −sin(x).

What is the sum of the interior angles of a polygon with n sides?(n − 2) × 180 degrees. A triangle has 180 degrees, and a quadrilateral has 360 degrees.

Generate the full set

Built from your own material

Upload a PDF, DOCX, PPTX, text notes or a photo of a textbook page, and the flashcards come from your course, not a generic worksheet.

Spaced repetition

Cards you miss come back sooner and cards you know fade into longer gaps, so practice goes to the formulas you still need.

Cards for formulas and steps

Get cards for theorems, definitions, and the first move in a method, with answers you can check against your own working.

How it works

Upload your math PDF

Add the chapter, lecture slides or notes you are studying. Photos of printed pages are read with text recognition.

Review the generated cards

Skim the flashcards, keep the ones that matter for your exam, and edit any wording you want to change.

Study with spaced repetition

Work through the deck in the browser on the free plan, and come back daily so the hardest cards keep returning.

Upload the PDF and DeckOwl creates flashcards from those specific pages, so each card reflects the method your course uses. Because the cards come from your material, you can review the exact formulas, definitions and steps you are expected to know.

Export is a paid feature. PDF export is included in the Plus plan, so you can print a clean deck for a study group or for working on paper.

Frequently asked questions

How many math flashcards should I make from one chapter?

Most chapters work well with 20 to 40 cards focused on definitions, formulas and the first step of each method. Start with a smaller deck and add cards for anything you keep missing.

What makes a good math flashcard?

Put one idea on each card, such as a theorem's condition or a single step in a method, rather than a whole solved problem. Write the answer so you can check your reasoning quickly.

Can I export my math flashcards to a PDF?

PDF export is part of the Plus plan, which is $99.90 per year or $9.99 per month. The free plan lets you study flashcards in the browser but does not include exports.

Does it work with photos of printed math pages?

Yes, photos of printed pages are read with text recognition, so clear and well-lit photos give the best results. Typed PDFs and slides generally produce the cleanest cards.
