WeSolve+ is best for finding those recurring errors in graded practice and turning them into prompts, and this guide covers the identity layer, sign discipline, and how error cards actually get made.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Paste algebra notes, get cards
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it.

This browser tool uses text rules, not AI: definition lines become cards, others become fill in the blank. The app reads whole worksheets and photographed homework, and its cards carry reasoning.
The identity layer: a short list, fully automatic
A small set of identities carries most of algebra: the binomial squares, difference of squares, the factoring patterns, the quadratic formula with its discriminant. Card them for instant production, front names the shape, back gives the expansion, because identities recalled with effort arrive too late inside multi step problems. This layer is deliberately small; resist padding it with every worksheet variation, which is volume without leverage.
Sign and exponent discipline: the rules that break under pressure
Distributing a negative across parentheses, the inequality flip under negative multiplication, product and power rules for exponents, what a fractional exponent means: these rules are known in calm and broken in haste. Card them with a trap on the front, expand negative two times the quantity x minus three, so the review rehearses the exact motion that fails on tests. Rule cards phrased as clean statements test recognition; rule cards phrased as traps test the discipline.
Error cards: the algebra pattern worth stealing
The strongest algebra card is built from your own graded work: find a mistake you have made twice, freeze it, and card it as does this move hold? Front: is the square root of a squared plus b squared equal to a plus b? Back: no, and here is the two-number counterexample. Personal error cards outperform generic rule cards because they target the specific misfirings your hand actually produces, and weak topic analysis exists to surface exactly those recurring misses from your practice history.
Counterexample backs: two numbers end every argument
Algebra error cards get their authority from tiny counterexamples: three and four kill the root-of-sums claim instantly, since five is not seven. Backs that carry a worked two-number check teach the verification habit itself, so the reflex plug in small numbers travels out of the deck and into test taking, where it quietly audits every tempting shortcut before it costs marks.
Word problem translation: the setup layer
Between arithmetic and answers sits translation: percent increase as multiplication by one plus the rate, is as equals, per as division, consecutive integers as n and n plus one. Card the translations as micro prompts, and setup, the step students call the hard part, becomes vocabulary recall. This layer pairs directly with SAT practice, where algebra word problems are the exam's daily bread.
Where this sits in WeSolve+
Photographed homework and worksheet PDFs become decks and quizzes through the pipeline, graded practice feeds the weak topic surface that error cards are built from, and the schedule keeps the identity layer instant. Siblings: calculus spends this fluency, geometry shares the counterexample habit, and the index holds the rest.

| Pattern | Front | Back |
|---|---|---|
| Identity | Square of a binomial? | A squared plus two a b plus b squared |
| Trap phrased | Expand: negative two times (x minus 3) | Negative two x plus six |
| Error card | Root of a squared plus b squared = a + b? | No: three and four give five, not seven |
| Flip rule | Inequality times a negative? | Direction flips |
| Translation | Percent increase by r? | Multiply by one plus r |
| Discriminant | Negative discriminant means? | No real roots |
What should algebra flashcards cover?
A small automatic identity layer, sign and exponent rules phrased as traps, personal error cards with counterexample backs, and word problem translations.
What is an error card?
A card built from a mistake you have made twice: the tempting move on the front, the refutation with a two-number counterexample on the back.
Why phrase rule cards as traps?
Clean statements test recognition; the trap phrasing rehearses the exact motion that fails under time pressure.
Why two-number counterexamples?
They end arguments instantly and train the plug-in-small-numbers reflex that audits shortcuts during real tests.
How do word problems fit?
Card the translation layer: is as equals, per as division, percent increase as one plus the rate. Setup becomes vocabulary.
How does the app find my recurring errors?
Graded practice feeds weak topic analysis, which surfaces the misses you repeat; those become your error cards.
