Math cards fail when the notation is a mess. Interact renders LaTeX next to ordinary formatted text, so a card can hold a formula and the steps that explain it.
Four ways to study math
Write formulas in LaTeX
Wrap math in dollar signs and it renders as proper notation: fractions, integrals, matrices. Everything else on the card is Markdown, so bold text and numbered lists work beside the formulas.
Flashcards in lessonsPut the steps on the back
An answer alone doesn't tell you whether you got there the right way. Put the result first and the steps under it, then grade yourself on the method.
How lessons workMake cards from your problem sets
Upload lecture notes or a chapter as a PDF, or a photo of a handwritten page, and Interact drafts cards from it with the math written in LaTeX.
PDF to flashcardsType short answers
For facts with one short answer, like a constant or the next term in a pattern, a typed answer exercise is quicker than a card.

What cards are good for in math
Cards won't replace problem sets. They cover what problem sets assume you remember: definitions, identities, theorem statements, and the first move for each kind of problem.
A few minutes of review a day keeps those ready, so your practice time goes to the problems.
Start with a prompt
The Describe option on the Create page turns a sentence into a set of interactives. This one is a reasonable first set. Change it to match what you're studying.

Common questions
Do I need to know LaTeX?
No. Generated cards come with the math already written. If you write your own, a handful of commands covers most coursework, and the Markdown doc has examples.
Will a dollar amount turn into math?
No. Prices like $5.00 are left alone.
Does the math render in the apps?
Yes. Formulas render on the web, iPhone, iPad, and Apple TV.
Is it free?
Making cards by hand is unlimited on every plan. The free plan includes 10 AI generations a month.
