MathGPT: free AI math solver
with every step explained.
Type a question or snap a photo of it, and MathGPT returns a step-by-step solution: the method, the working, the final answer, and an independent check you can repeat yourself. Free for high-school, AP, and university students.

The calculators students open most.
Each one shows the working line by line, not just the result, so you can reproduce the step-by-step method yourself in an exam where no calculator is allowed.
Which one you need depends on what you already know.
A calculator applies a method you have already chosen. The solver reads the problem in your own words and works out which method fits. If you know what to do, use a calculator; if you are stuck on the setup, start with the solver.

Questions about MathGPT.now
Is MathGPT.now free?
Yes. The AI math solver, graphing and scientific calculators, learning guides, course practice, and exam-preparation resources are free to use. Most tools work without an account.
Which levels and subjects does MathGPT.now support?
MathGPT.now supports high-school, AP, and university mathematics, including arithmetic, algebra, geometry, trigonometry, precalculus, calculus, statistics, probability, linear algebra, differential equations, and discrete mathematics. Start from the <a href="/subjects">math subjects and courses</a> page.
Does the AI math solver show its steps?
Yes. A response separates the question, method, meaningful working, final answer, and verification. You can ask a follow-up question about a doubtful step or use a <a href="/calculators">focused calculator</a> to check the result.
Can an AI-generated math answer be wrong?
Yes. AI can misread notation, choose an invalid method, or make a calculation error. Check domains, units, substitutions, graphs, or a second method, and follow your school's assessment rules.
