The best AI math solver for learning is the one that shows every step, lets you check each one, and does not hide the explanation behind a paywall. Photomath still gives basic step-by-step explanations for free, Symbolab and Wolfram|Alpha go deeper on calculus and computation once you pay, and a few newer tools add photo input, PDF homework and voice tutoring.
Getting an answer is the easy part. The harder question is which one leaves you able to solve the next problem on your own, on a test, with no phone in your hand.
This guide compares seven math solver AI tools on that question: what each shows for free, what it accepts as input, how far its math goes, and how to use it without turning it into a crutch.

"Free steps" describes what the free version shows, as each vendor lists it today. Plans change often, so check the app store page before you rely on any one of them for a whole semester.
How We Evaluated These Math Solvers
Four criteria decided the order.
Steps you can read for free. A solver that shows only the final answer is a calculator with better marketing. We ranked tools higher when the free version explains the method, not just the result.
Input that matches real homework. Most homework arrives as a printed worksheet, a textbook page or a handwritten problem. Photo input that reads handwriting matters more than a polished keyboard.
Scope. Some apps stop at algebra and basic calculus. Others reach into differential equations, statistics, physics and chemistry. We noted where each one stops.
Room to think. The best tools let you reveal one step at a time, ask why a step works, or try the next step yourself before seeing it. That design choice turned out to matter more than raw accuracy, for reasons covered further down.
1. Photomath: Best Free Step-by-Step Camera Solver
Photomath is the app most students picture when they hear "photo math solver." You point the camera at a problem, printed or handwritten, and it returns a solution broken into small steps, often with more than one method to choose from.
What you get for free
According to its Play Store listing, step-by-step explanations are included in the basic version at no charge, along with word problem instructions, interactive graphs and a scientific calculator. That is still rare in this category, and it is the main reason Photomath ranks first.
Photomath Plus adds animated tutorials, extra "how" and "why" tips, and worked solutions for hundreds of textbooks. Those are useful but not required to learn from the app.
Where it falls short
Photomath is now a Google product, and recent reviews complain that some problems return "we can't solve this one yet" and that features once free moved behind Plus. Coverage runs from arithmetic through calculus, so a university student in linear algebra or differential equations will hit its ceiling.
Best for: high school and early college students who want free, readable steps from a photo of the problem.
2. Primo Notes AI Math Solver: Best Free Check With No Account
The free AI math solver on the Primo Notes website takes a typed problem or a photo of one, including handwriting, textbook screenshots and worksheets, and returns a full step-by-step solution with an explanation of each step. It covers algebra, geometry, trigonometry, statistics and calculus.
Why it ranks here
There is no account, no login and no trial to cancel. You get 10 free uses a day, shared across the site's free AI tools, and every solution shows the full working rather than a teaser. For checking a few homework problems at night, that is often all you need.
Where it falls short
It is a web tool, not a dedicated math app. There is no graphing calculator, no practice problem bank and no textbook library. The 10 daily uses are shared with the other free tools, so a long problem set will run out of uses.
Best for: students who want a free AI math solver with full steps for a handful of problems, without installing anything or signing up.
3. Symbolab: Best for Calculus and Practice Sets
Symbolab focuses on step-by-step solutions across a wide range, from elementary arithmetic to differential equations. Its strength is structure: it groups problems by topic, generates practice exercises and tracks progress in a dashboard.
Strengths
The calculus coverage is deep, with limits, derivatives, integrals and series handled cleanly. An interactive graphing calculator and a geometry tool with drawing support help when a picture makes the algebra click. A Chrome extension solves problems directly on a web page, which helps with online homework platforms.
Weaknesses
Full step-by-step solutions and full feature access sit behind a paid subscription, so the free experience shows less of the method than Photomath does. Review sites also flag the same risk this whole category carries: leaning on it for every problem can weaken independent problem solving.
Best for: calculus students who want practice problems alongside the solutions.
4. Wolfram|Alpha: Best for Computation Beyond Homework
Wolfram|Alpha is not an AI chatbot in the modern sense. It is a computational engine built by Wolfram Research, the makers of Mathematica, and it answers by computing rather than predicting text. That makes it unusually reliable on the math it understands.
Strengths
You can type questions in plain language, such as "integrate x squared times sine x" or "solve 3x + 7 = 22," and it parses them. Its range goes far past school math into physics, chemistry, engineering, economics and statistics. For checking a result, it is hard to beat.
Weaknesses
The free version gives answers, plots and related facts. Step-by-step solutions, practice problems and file uploads are part of Wolfram|Alpha Pro. Some universities provide Pro access free to their students, so check your school's software page before paying. It is built around typed queries rather than the camera, so it suits typed problems best.
Best for: college students in STEM and anyone who needs to verify a computation, not just a homework answer.
5. Mathos AI: Best for Homework PDFs
Mathos AI, also known as MathGPTPro, combines a step-by-step solver with an AI tutor. Its standout feature is a PDF homework helper: you upload the assignment PDF and it solves problems directly in the document, with room to annotate and take notes.
Strengths
Input options are broad. Beyond photos and PDFs, the tutor accepts voice and drawing, so you can sketch a triangle or say a problem out loud. It also bundles a graphing calculator and a set of dedicated calculators for fractions, integrals, limits and more, and it reaches into physics, chemistry and engineering.
Weaknesses
Mathos claims on its app listing that its model is 20% more accurate than ChatGPT. That is the company's own figure and not an independent test, so treat it as marketing until someone outside the company measures it.
Best for: students whose homework arrives as PDFs, and anyone who likes to talk or draw through a problem.
6. Gauth: Best for Mixed Subjects and Live Help
Gauth positions itself as a study companion more than a math app. You take a photo, it crops the question automatically, and it returns an answer with animated step-by-step instructions. It also covers physics, chemistry and biology.
Strengths
Two features set it apart. An AI Live Tutor lets you ask follow-up questions by voice and see the explanation drawn on a whiteboard. When the AI is not enough, human experts are available around the clock for math and science questions. In October 2026 Gauth added a continuous digital canvas for working through larger topics.
Weaknesses
Gauth's own listing says it solves faster and more accurately "especially with the support of Gauth AI Pro," which signals that the best results sit in the paid tier. The ease of snapping a photo and getting a finished answer is also the exact pattern that research links to weaker learning, as the next sections show.
Best for: students who need help across several science subjects and value a live explanation.
7. Mathway: Best for Fast Answers Across Many Courses
Mathway, owned by Chegg, covers basic math, pre-algebra, algebra, trigonometry, precalculus, calculus, statistics, finite math, and even chemistry and physics. You type or photograph the problem and get an answer almost instantly.
Strengths
The breadth is real, and the interface is simple. For checking whether a final answer is right, it is quick and dependable across a wide range of courses.
Weaknesses
Full step-by-step solutions require a paid subscription. On the free plan you mostly see the answer, which makes Mathway the weakest learning tool on this list despite its range. Review aggregators rate it lower than its app store scores suggest, mostly over the paywall.
Best for: checking answers quickly, not learning the method.
What Happened to Microsoft Math Solver
If you are searching for Microsoft Math Solver, it is gone as a standalone app. Microsoft retired it on July 7, 2025. The old Math Solver address now points to Math Assistant in OneNote, which is available in OneNote for Microsoft 365 Education.
If your school gives you a Microsoft 365 Education account, Math Assistant is worth a look, because it works inside the notes you already keep. If not, Photomath and the free web solver in pick 2 are the closest free replacements for the photo-plus-steps workflow it offered.
Why an AI Math Problem Solver Needs Guardrails
Every tool on this list can make homework faster. The best evidence on whether that helps you learn comes from a large field experiment published in PNAS in 2025.
What the study found
Researchers at the Wharton School gave nearly a thousand high school math students in Turkey access to one of two GPT-4 tutors. One mimicked a standard ChatGPT interface. The other was prompted to give teacher-designed hints instead of answers.
During practice, both helped: grades rose 48% with the plain version and 127% with the hint-based tutor. Then access was removed for the exam. Students who had used the plain version scored 17% lower than students who never had AI at all, according to the published study. The hint-based tutor largely avoided that drop.
The students who learned less did not notice. They did not report that they learned less or expected to score worse.
What it means for choosing a solver
The researchers also noted that the plain GPT-4 often made mistakes on the math itself. So an unguarded chatbot can be wrong and still erode your skill at the same time.
The lesson is about design. A solver that reveals one step at a time, explains why, and lets you try first works like the hint-based tutor. A solver that hands over the finished answer works like the version that hurt exam scores.
What to Look for in an AI Math Solver
Use these questions to judge any math solver AI, including ones not on this list.
Can you see the method for free?
If the free version only shows answers, you are paying to learn. Photomath and the free web solver in pick 2 show steps without payment; Mathway, Symbolab and Wolfram|Alpha put full steps behind a subscription.
Can you reveal one step at a time?
Step-by-step reveal lets you try the next move before seeing it. That small habit converts the app from an answer key into practice.
Does it read your actual homework?
Test it on a photo of your own handwriting, not a clean demo problem. An AI math solver from a picture is only useful if it reads your sevens and your exponents correctly.
Does it reach your level?
High school algebra is handled everywhere. Linear algebra, differential equations and proofs are where tools separate. Wolfram|Alpha and Symbolab go furthest; Photomath stops at calculus.
Does it compute or predict?
Wolfram|Alpha computes. Chat-style tools predict text that looks like a solution, which is why the Wharton study saw errors. For anything graded, verify a chatbot's answer with a computational tool.
How to Use a Math Solver Without Losing the Skill
The research points to a simple routine. You get the speed of a solver while keeping the learning that the exam will test.
- Attempt first. Spend at least five honest minutes on the problem before opening any app. Write down where you got stuck.
- Reveal one step. Open only the step after your sticking point, then close the app and finish the problem yourself.
- Explain it back. Say out loud why each step works. If you cannot, you have found the gap.
- Redo it cold. The next day, solve a similar problem with no app. That is the only test that matches the exam.
The "explain it back" step is the core of the Feynman technique, and it works especially well for math, where a confident-looking step often hides a rule you never understood.
The Primo Notes app can help with the parts around the solving. Photograph your class notes or the worked example from the board, and the app turns the page into a written note. From there you can generate a quiz or flashcards on the method, or open a Feynman session and explain the steps out loud while the app probes what you skipped.
For subjects beyond math, the same rules apply to the wider group of AI homework help tools: hints before answers, and your own attempt before either.
Conclusion
The tools on this list differ in what they show you for free, what they accept as input, and whether they leave room for you to think.
Photomath remains the strongest free option for camera solving with steps. Symbolab and Wolfram|Alpha go deeper for calculus and computation once you pay. Mathos AI and Gauth add PDF input, voice and live tutoring, and Mathway is best kept for checking answers. Microsoft Math Solver now lives on only as Math Assistant in OneNote for Education.
The Wharton experiment is the reason the choice matters: unrestricted answers raised practice scores and lowered exam scores, while hints preserved learning. Pick a solver that explains, reveal one step at a time, and redo the problem on your own the next day.
