AI Math Solver

What the math solver does

Type an equation or a word problem and get a solution in numbered steps, with every calculation written out. Before it gives the final answer, the solver checks the result by putting it back into the problem or by solving another way. If the check fails, it looks for the error and corrects it. The final answer appears in bold, with units when the problem has them.

The tool uses Grok 4.20, the fast model in our chat, and all formulas come out as plain text with symbols such as ×, ÷, √, ² and π, so they display properly on any phone or computer without special formatting. It handles arithmetic, percentages, algebra, geometry, unit conversions, basic statistics and many school and university topics.

How to solve a problem

1. Type the problem. Write equations the way you would on paper: 5x − 3 = 2x + 9, x² − 5x + 6 = 0, or a full word problem in your own words. Use ^ or ² for powers and / for fractions if that is easier.
2. Choose the solution style. Every step explains each move briefly. Key steps only is compact, for when you just need to compare with your own work. First step and a hint starts you off without giving the final answer away. Check my solution reviews your own working, written after the problem, and points to the first wrong step.
3. Set the level: middle school, high school or university. It changes the wording and the methods used.
4. Generate, then copy the solution, regenerate, or continue in the chat to ask about a particular step.

Tips for reliable results

• Use brackets generously. (x + 3)/2 and x + 3/2 are different problems, and the model can only solve what you wrote.
• Copy word problems in full. Every number and unit matters, including the ones that look unimportant.
• Do the problem yourself, then check. Check my solution shows exactly where your working went wrong, which is the quickest way to improve.
• For harder problems, give it time to think. Grok 4.20 answers immediately without a reasoning phase. For proofs, multi-step calculus or competition-style puzzles, continue in the chat and switch to Grok 4.3 Thinking, which works through the problem before it replies.

Example from a real run

We gave the solver the second sample with default settings:

A phone costs 360 dollars after a 25% price cut. What was the price before the cut, and how much money was saved?

Final answer: 480 dollars before the cut, 120 dollars saved. The common trap here is taking 25% of 360 and adding it back, which gives 450; the step-by-step layout makes it clear why that is wrong.

Limits you should know

• AI can still slip. Language models occasionally make arithmetic or algebra errors even with a built-in check. For anything that counts, such as an exam answer, a tax figure or an engineering value, verify with a calculator or a second method.
• Text only. This page does not read photos of handwritten problems. In the chat, you can attach a clear picture of the problem instead.
• No graphs or diagrams. It can describe a graph in words but does not draw one.
• Learning matters more than answers. If you are preparing for a test, the hint style will do more for you than full solutions.

Math Solver FAQ

Is the math solver free?

Yes, with no sign-up. A solution takes one of the 30 free messages each visitor gets per day; the chat and the other tools count toward the same number.

How do I type powers, roots and fractions?

Write x^2 or x², sqrt(9) or √9, and 3/4 for fractions. Brackets make the meaning clear when expressions get longer.

Can it explain in my language?

Yes. Write the problem in Portuguese, French, Vietnamese or another language and the steps come back in that language.

Why are there no fancy formulas?

On purpose. Plain-text math works everywhere, can be copied into any document and does not break on small screens.

Can it explain why a method works?

Yes, ask in the chat: explain the method behind a problem. For questions beyond maths, try the Homework Helper, and see how thinking models differ in our guide to reasoning models.
