Math Flashcard App

Math isn't only problem-solving. Every problem you solve leans on things you have to remember: formulas, identities, definitions and the steps of a method.

Space Repeat lets you write them in real math notation, so a fraction looks like a fraction and an integral like an integral, and brings each card back right before you'd forget it.

Why spaced repetition works here

Most math exams test whether you can apply a method under time pressure, and you can't apply what you can't recall. When the quadratic formula, the derivative rules or the unit circle come to mind instantly, your working memory is free for the actual problem. Spaced repetition keeps those foundations within reach for the whole course, not just the week you learned them, while practice problems build the skill of using them.

Ideas for your flashcards

  • Formulas and identities: areas and volumes, the quadratic formula, trig identities
  • Definitions and theorems, with the conditions they need
  • Derivative and integral rules, and when each one applies
  • Method steps: completing the square, integration by parts, solving systems

Example math flashcards

Shown the way Space Repeat shows them, formulas and all: one clear question, one short answer.

Question

The quadratic formula: solutions of ax2+bx+c=0ax^2 + bx + c = 0

Answer

x=−b±b2−4ac2ax = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Question

Area of a circle with radius rr

Answer

A=πr2A = \pi r^2

Question

What is ddx ex\dfrac{d}{dx}\,e^x?

Answer

exe^x: it is its own derivative

Question

The Pythagorean identity

Answer

sin⁡2θ+cos⁡2θ=1\sin^2\theta + \cos^2\theta = 1

How to use spaced repetition for math

Make a card for each formula, rule and definition as your class reaches it, and write the formula itself on the back, not just its name. The Math & code toolbar inserts the notation if LaTeX is new to you.

Review your cards before you start a problem set: ten minutes of recall makes the problems faster. Keep doing the problems; the cards just make sure the tools are ready.

How Space Repeat works

Smart scheduling

The algorithm tracks every card and shows it again right before you would forget it. No manual planning required.

Formulas and code

Fractions, integrals, chemical equations and highlighted code look right on every card. Plain text works too.

Free during the beta

Every feature, spaced repetition included, is free to use while Space Repeat is in beta. Early users will be looked after when pricing arrives.

Frequently asked questions

Does Space Repeat come with ready-made flashcards for this?

Yes. New accounts can add starter decks for math: Pre-Algebra Essentials, Algebra 1: Equations, Lines and Factoring, Geometry Formulas, Algebra 2 and Trigonometry, Calculus: Derivatives, Calculus: Integrals, Statistics and Probability, Linear Algebra Basics. They're ordinary decks, so you can edit, add or delete cards, and write or import your own alongside them.

Can I write math formulas on flashcards in Space Repeat?

Yes. Put math between dollar signs and it's rendered with LaTeX, the notation math is written in: fractions, exponents, roots, integrals, sums, matrices and Greek letters. If you don't know LaTeX, the Math & code toolbar under each card field inserts the common pieces and shows a live preview.

Should I put practice problems on math flashcards?

Mostly no. Cards work best for things with one clear answer: a formula, a definition, the first step of a method. Keep practice problems for problem sets, and use cards so the facts those problems need are already in your head.

Is Space Repeat free for math students?

Yes, it's free while Space Repeat is in beta, with up to 50 decks and 100 cards per deck. Early users will be looked after when pricing arrives.
