# Best math AI solver: seven checks to run yourself

> The best math AI solver shows each step, checks its own result, says when a problem is ambiguous, reads word problems, writes math you can copy, states its price before you solve and is honest that AI can be wrong. This page lists those seven checks and a free set of eight test problems with known answers, so you can compare any tools, including this one, on the problems you actually need.

The best solver for you is the one that gets your kind of problem right and shows working you can follow. These checks and test problems let you find out in ten minutes.

## Seven checks for a math AI solver

- **It shows every step**: A bare answer cannot be checked or learned from. Look for one operation per line, with the result of each.
- **It checks its own result**: A good solution substitutes the answer back or recomputes it another way, and shows that check.
- **It flags ambiguity**: Type 6/2(1 + 2). A careful solver points out the two readings instead of silently picking one.
- **It reads word problems**: Paste a story problem. The solver should define the variables and write the equation, not just print a number.
- **Its math is easy to copy**: LaTeX code and images are hard to reuse. Plain notation such as x^2 and sqrt(x) pastes anywhere.
- **The price is clear**: You should know what a solution costs before you press solve, and a failed attempt should not be charged.
- **It is honest about limits**: No solver is always right. Prefer a tool that says so and tells you how to verify over one that promises 100% accuracy.

## How to compare math solvers in ten minutes

1. **Pick five test problems**: Use the set below or problems from your own course, with answers you already know.
2. **Run them in each tool**: Use the same wording everywhere, and note the cost and the time each one takes.
3. **Score answer and working**: One point for the right answer, one for steps you could follow, one for a check. Repeat with your hardest topic.

## A free test set with known answers

Each problem has a known answer and a trap that catches careless solvers. Copy them into any tool:

- 6/2(1 + 2): a careful reply names both readings, 9 (left to right) and 1 (implied multiplication first)
- A shirt costs $40 after a 20% discount. What was the original price? Answer: $50, not $48
- Solve sqrt(x + 7) = x - 5. Answer: x = 9 only; x = 2 is an extraneous root
- Solve x^2 = 2x. Answer: x = 0 or x = 2; dividing both sides by x loses x = 0
- Integrate 1/x dx. Answer: ln|x| + C, with the absolute value
- Two dice are rolled. What is the probability that the sum is 7? Answer: 6/36 = 1/6
- A bat and a ball cost $1.10 together, and the bat costs $1.00 more than the ball. What does the ball cost? Answer: $0.05
- What is the sum of the interior angles of a hexagon? Answer: (6 - 2) × 180° = 720°

## What this page does not claim

We have not published a benchmark of math solvers, and this page does not rank brands. A single test set is not a benchmark either: results vary with the topic and the wording, and models are updated often. Run the checks on the problems you care about, including on Math Solver Calculator, and keep the tool that does best on them.


## How Math Solver Calculator approaches the checks

It runs Claude Sonnet 5 with rules to show one step per line, write a check before the answer, note ambiguous readings and write plain-text math. The price is shown before you solve (1 credit per problem, $0.08 to $0.10) and failed jobs are refunded. It does not read photos and does not draw graphs yet, so if you need those, weigh that in your comparison.


## Kinds of math solvers compared

| | Math Solver Calculator | Symbolic algebra software | General AI chatbot |
| --- | --- | --- | --- |
| Word problems | Sets up equations from the story | Usually needs the equation typed | Reads them; the format varies |
| Steps | Required in every solution | Depends on the product and plan | When you ask for them |
| Exactness | Can slip; a written check is included | Exact symbolic computation | Can slip; checks only if asked |
| Output | Plain-text math | Rendered formulas, often graphs | Often Markdown or LaTeX |
| Pricing | 1 credit per problem | Free tiers and subscriptions vary | Free tiers and subscriptions vary |

## Simple pricing, by the problem

- Starter: $7.99 / month, 100 credits
- Pro: $19.99 / month, 250 credits
- Tutor: $49.99 / month, 650 credits
- Mini: $4.99, 50 credits
- Plus: $14.99, 160 credits
- Max: $34.99, 420 credits

## Choosing a math AI solver

### What is the best math AI solver?

The one that gets your kind of problem right and shows working you can follow. Run the seven checks and the test set on this page in two or three tools, score them, and keep the winner. We do not publish a ranking because we have not run a fair benchmark.

### Is Math Solver Calculator the best AI math solver?

It is built for the checks that matter for learning: steps, a written check and plain-text math. It also has limits: no photo input yet and no graphs. Test it on your own problems before you buy a larger pack.

### Are AI math solvers accurate?

Often, but not always. Language models can make arithmetic slips and misread problems, especially long ones. A solver that checks its own result catches some of this; you catch the rest by reading the check and comparing it with your own working.

### Can I use a math AI solver for homework?

It depends on your school and the assignment. Using steps to learn a method or check your work is usually fine; handing in AI work as your own may not be. Follow your teacher's rules.

## Run the checks on Math Solver Calculator

Paste a problem from the test set, read the steps and the check, and judge for yourself. Each problem uses 1 credit; the account is free.
