The most frustrating part of getting stuck in math often isn't not knowing the answer — it's not being able to see where you went wrong. Per the OECD's PISA 2022 results, roughly a third of 15-year-olds score below baseline math proficiency; but the issue is rarely intelligence, it's not spotting which step of an equation you slipped on. Staring at a problem for 40 minutes wondering "where did that −3 come from?" happens to nearly everyone.

Ryna AI doesn't just spit out the result like an answer machine. It solves the equation step by step and, on every line, states what it did and why. For a quadratic it computes the discriminant and finds both roots; for a two-variable system it tells you whether it used substitution or elimination; for an inequality it never forgets to flip the sign when multiplying by a negative. Most importantly, it plugs the root back into the original equation and shows the equality holds, so the answer isn't left hanging.

The output is always a "solution draft to be verified" — the AI can, rarely, slip on arithmetic, so double-check the last step yourself (Ryna already shows the substitution). On the free plan you can solve near-unlimited equations per day. With Plus (399.99 TRY/mo) you can photograph the handwritten problem in your notebook or a textbook page and upload it (image analysis), hand over an entire problem set as a PDF, and lean on deep-thinking mode for multi-step systems.

Why use Ryna AI for this

Every step visible: not just the result but each algebraic line and the reason for it — 'added 3 to both sides', 'factored out the common term'.

Four types under one roof: linear, quadratic (factoring / discriminant / completing the square), two- and three-variable systems, and inequalities.

Verifies by substitution: plugs the x it found back into the original equation and shows the equality holds — closing the 'is my answer right?' question.

Multiple methods for the same equation: ask 'solve x²−5x+6=0 by both factoring and the formula' and it lays out both side by side, telling you which is faster.

Catches the traps: sign flip when multiplying an inequality by a negative, zero denominators, negative under a square root, extraneous roots in radical/rational equations — it flags them.

Reads from an image (Plus): photograph the handwritten or textbook problem, upload it, and let it solve without you retyping anything.

How it works — step by step

  1. 1

    Enter the equation

    Go to chat.rynaai.com and type the equation as text (use ^ for exponents, * for multiplication), or on Plus photograph the problem in your notebook and upload it. Avoid ambiguous notation: write '2x^2', not '2x2'.

  2. 2

    Say what you want

    Don't just say 'solve'; say 'explain each step, tell me which method you used, and verify by substitution'. You can also set a level, like 'explain at a 10th-grade level'.

  3. 3

    Read the steps, ask 'why'

    If a step is unclear, ask 'why did we divide both sides here?'. The goal isn't the ready answer but learning the method — so you can apply it yourself on the next problem.

  4. 4

    Make it verify

    Say 'substitute the roots back into the original equation and check the equality'. If the substitution doesn't hold, there's an error somewhere; ask Ryna to re-examine that step.

Example: input → output

You ask

Solve 2x² − 7x + 3 = 0. Show the discriminant, find the roots, and verify by substitution.

Ryna AI returns

Given: 2x² − 7x + 3 = 0 → a = 2, b = −7, c = 3 1) Discriminant: Δ = b² − 4ac = (−7)² − 4·2·3 = 49 − 24 = 25 Since Δ > 0, there are two distinct real roots. 2) Roots (formula): x = (−b ± √Δ) / 2a = (7 ± √25) / 4 = (7 ± 5) / 4 x₁ = (7 + 5) / 4 = 12/4 = 3 x₂ = (7 − 5) / 4 = 2/4 = 1/2 3) Verification (substitution): For x = 3: 2·(3)² − 7·(3) + 3 = 18 − 21 + 3 = 0 ✓ For x = 1/2: 2·(1/2)² − 7·(1/2) + 3 = 0.5 − 3.5 + 3 = 0 ✓ Result: x = 3 or x = 1/2. Both satisfy the equation. Tip: this one also factors — (2x − 1)(x − 3) = 0 gives the same roots. Want me to show that method step by step too?

Pro tips

  • Always ask for verification explicitly: 'substitute the root and show the equality' — when Ryna does this, any arithmetic slip is caught instantly by both of you.
  • Ask for the method's name ('is this completing the square?') — so you can find the same topic in a textbook or video and reinforce it.
  • On quadratics, ask 'which method is fastest for this equation?' — some factor easily and you never need to grind through the formula.
  • Ask 'what's the most common mistake on this type?' — you see the trap before you fall into it, especially sign errors and values that zero out the denominator.
  • When uploading a photo (Plus), check in the first line that Ryna read the exponents and signs correctly — handwritten 'x²' vs 'x2' and '−' vs '=' are easy to confuse.
  • If you need a graph, Ryna doesn't draw images; instead ask for the vertex, roots, axis of symmetry, and a few (x, y) points, then plot them yourself in Desmos or on graph paper.

Common mistakes to avoid

  • Taking the final number without verifying — always have Ryna substitute the root and show the equality; arithmetic slips are rare but real, and substitution catches them instantly.
  • Writing ambiguous notation: '2x2' could read as 2x² or 2·x·2. Use '^' for exponents, '*' for multiplication, and name the variable clearly.
  • Not checking the sign flip when multiplying/dividing an inequality by a negative — confirm with your own eyes that Ryna turned '>' into '<' at that step.
  • Copying the answer without learning the method — you won't be able to solve the same problem alone in an exam; ask 'why' and internalize each step.
  • Ignoring the domain in radical/rational equations — screen out extraneous roots that make a square root negative or a denominator zero; ask Ryna to check each root against the domain.

FAQ

Does Ryna always solve math correctly?

Usually yes, but the AI can, rarely, slip on arithmetic. That's why Ryna substitutes the root back and verifies on every solution; you should also check the final number yourself. If the substitution satisfies the equality, the solution is solid.

Can I photograph the problem in my notebook and have it solved?

Yes. With Plus (399.99 TRY/mo) image analysis you can photograph a handwritten equation or a textbook page and upload it. It's worth confirming in the first line that Ryna read the problem correctly (exponents, signs).

Is it okay to have Ryna do my homework or exam questions?

Ryna is a learning and checking tool, not a source to copy from. Submitting its solution verbatim as your homework violates most schools' academic-integrity rules and undermines the real goal — learning the method; you'll be on your own in the exam. The right use: have it check your own solution, understand the step you're stuck on, and practice with similar problems.

Can it draw graphs?

No, Ryna doesn't produce images or graphs. But it will give you the parabola's vertex, roots, axis of symmetry, and a table of points; plot those yourself in Desmos or on graph paper to draw the graph.

Which equation types does it handle well?

It's strong on linear and quadratic equations, two- and three-variable systems, inequalities, and most rational/radical equations. For very advanced work (long proofs, complex integrals/differentials), always check the solution step by step.
