Snap a math problem. See every step.
A free AI math problem solver inside MathPad. Take a photo of a problem and get a step-by-step solution for algebra, calculus, geometry, trigonometry and more, explained so a student can follow it.
Snap, see the steps, learn it.
Built for kids and teens learning math, not for skipping it.
Snap the problem
Point your phone at the problem on the worksheet or in the textbook. You can also upload a picture or type the problem in.
See it one step at a time
Each step comes with a short explanation of why it works. The next step stays hidden until you ask, so you can try it first. The answer comes last.
Learn the method
The goal is the next problem, the one you do yourself. Work through the steps on paper, then try a similar problem on the pad.
From times tables to derivatives.
Arithmetic
Whole numbers, decimals, fractions, order of operations and percentages.
Algebra
Linear and quadratic equations, simplifying, expanding and factoring expressions.
Geometry
Area, perimeter, volume, angles and the Pythagorean theorem.
Trigonometry
Sine, cosine and tangent, right triangles and trig equations.
Calculus
Derivatives, integrals and limits, with each rule named as it is used.
Statistics
Mean, median, mode, range and simple probability.
MathPad checks the AI’s work.
- Arithmetic is recomputed by MathPad’s own math.
- Linear and quadratic equations: every solution is plugged back in, and none can be missing.
- Derivatives, integrals and simplified expressions are tested at several points.
- Each solution says whether it was double-checked. If MathPad can’t check it, or its check disagrees, you see that too.
- MathPad checks the math, not how the photo was read, so compare the problem shown with your page.
What “free” means here.
- Solving uses AI credits from MathPad’s free AI allowance. New accounts start with a 14-day trial with more.
- When the day’s credits are used, they refill the next day. The pad and practice never use credits.
- AI can misread a messy photo or make a mistake, so check answers that weren’t double-checked.
- Photos are not saved, and nothing about your child is sent with them.
Questions about the solver
Is the math solver really free?
Yes, within MathPad’s free AI allowance. Each solve uses a few AI credits. New accounts start with a 14-day free trial with a larger daily allowance; after that the free plan includes a smaller daily and monthly allowance, which covers a few photos a day up to a monthly limit. Daily credits refill each day. Children linked to a parent share the family’s allowance. No card is needed.
What kinds of math can it solve?
Arithmetic, fractions and decimals, algebra (linear and quadratic equations, simplifying, expanding and factoring), geometry, trigonometry, calculus (derivatives and integrals) and basic statistics. It works best on one or two clearly written problems per photo, and solves up to five at a time.
How does it check the answers?
After the AI writes a solution, MathPad re-checks it with its own math where it can: it recomputes arithmetic, plugs solutions back into linear and quadratic equations and makes sure none are missing, and tests derivatives, integrals and simplified expressions numerically at several points. Solutions that pass are marked double-checked. When a problem type can’t be checked, the solution says so, and if MathPad’s own check disagrees, it tells you to look again.
Can the solver make mistakes?
Yes. AI can misread a messy photo or make an error, which is why MathPad shows whether each answer was double-checked. Treat an answer that wasn’t checked as a starting point and work through the steps yourself.
Won’t kids just copy the answers?
The solver is built for learning. Students see one step at a time, with a nudge to think about the next move before revealing it, and the answer comes last. Grown-ups can open all the steps at once. A child who has homework open in MathPad sees a reminder that the solver is for learning how, not for doing the homework.
Do you keep the photos?
No. The photo is read in memory, sent to the AI service to be solved, and then discarded. MathPad does not save the image, and nothing about the child, such as their name or grade, is sent with it.
Do I need an account?
Yes. Sign in with an email link, with no password and no card, and the solver is in the MathPad app on phones, tablets and computers.
