Why generate your own rules deck

Printable sheets list the standard rules, but your class may use different notation or cover different chapters. Upload your own notes and DeckOwl builds math rules flashcards that match them.

Cards come from your own lecture notes, textbook pages or worksheets.
Each card has a rule name on the front and the exact statement on the back.
Spaced repetition schedules reviews for rules you keep missing.
Free plan includes 3 generations per month; Plus removes the limit.

Example algebra and calculus rules flashcards

Product rule for derivatives?d/dx[f·g] = f′g + fg′ (derivative of the first times the second, plus the first times the derivative of the second)

Quotient rule for derivatives?d/dx[f/g] = (f′g − fg′) / g² (the denominator is squared, so keep the subtraction order in mind)

Distributive property?a(b + c) = ab + ac (multiply the outside term by each term inside the parentheses)

Difference of squares?a² − b² = (a − b)(a + b) (it only works for subtraction, not for a sum of squares)

Exponent rule for multiplying powers with the same base?x^m · x^n = x^(m+n) (add the exponents, since the base stays the same)

Generate the full set

Built from your material

Upload PDFs, slides, notes or photos of a worksheet. The cards come from the rules your class actually uses.

Spaced repetition

Cards you miss come back sooner, so formulas like the quotient rule stick without re-reading the whole chapter.

Study in the browser

Start free with no credit card. Review cards on any device, and add PDF, DOCX, Anki or CSV export on Plus.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of the page you want to study.

Review the generated cards

Check the rules, edit anything that does not match your class, and keep the cards you need.

Study with spaced repetition

Open the deck daily. Missed rules return more often until you can recall them without looking.

Good math rule cards pair a name with a precise statement, such as the product rule or the difference of squares. Writing the rule in your own terms and testing yourself from the back of the card builds recall faster than rereading a sheet.

If your notes are photos, DeckOwl reads the text from the image first, so handwritten-style pages can still become a deck you can review.

Frequently asked questions

How do I memorize math rules without just rereading them?

Test yourself by stating the rule from the name alone, then check the statement on the back. Spread your reviews over several days, and add a worked example for any rule you still mix up with another.

Should I memorize formulas or learn where they come from?

Learn both if you can. Memorized rules help on timed tests, while knowing why the product rule works makes it easier to recall after a few weeks.

Can I export my math rules flashcards?

Yes, on the Plus plan at $39 per year or $7.99 per month you can export to PDF, DOCX, Anki and CSV. The free plan lets you study cards in the browser without exports.

Does DeckOwl work with photos of my class handouts?

Yes. Photos of pages are read with text recognition, so you can upload a handout and generate cards from the text it contains.
