# Photo Math Solver

> Photo Math Solver is a free Chrome and Edge extension that solves maths from a screenshot: select a problem anywhere on screen and a sidebar returns typeset step-by-step working, without retyping it into a solver.

- The extension runs in the browser on Windows, Mac and Chromebook. There is no web solver on this site: every page below is documentation or explanation, and problems are solved in the extension.
- Every math page opens with a three-sentence answer-first block; https://photomathsolver.app/llms-full.txt carries those blocks and each page's FAQ in full.
- Content is English unless a page is listed under "Other languages".

## Math areas

- [Pre-Algebra Solver](https://photomathsolver.app/en/pre-algebra): Photo Math Solver covers the pre-algebra core: one-step and two-step equations, percentages, ratios, fractions and the word problems built on them.
- [Algebra Solver](https://photomathsolver.app/en/algebra): Photo Math Solver handles the algebra a school or first-year course actually sets: linear equations, quadratics, systems of equations, and the word problems that turn into them.
- [Geometry Solver](https://photomathsolver.app/en/geometry): Photo Math Solver works through geometry problems involving lengths, angles, area, perimeter, surface area and volume, including diagrams captured straight from the page.
- [Trigonometry Solver](https://photomathsolver.app/en/trigonometry): Photo Math Solver covers trigonometry from right-triangle ratios through identities, the laws of sines and cosines, and trigonometric equations.
- [Calculus Solver](https://photomathsolver.app/en/calculus): Photo Math Solver handles the working core of a single-variable calculus course: limits including indeterminate forms, derivatives by every standard rule, and both indefinite and definite integrals.

## Math topics

- [One-Step Equations Solver](https://photomathsolver.app/en/pre-algebra/one-step-equations): A one-step equation is solved by applying the single inverse operation to both sides: add what was subtracted, subtract what was added, multiply by what divided, divide by what multiplied.
- [Two-Step Equations Solver](https://photomathsolver.app/en/pre-algebra/two-step-equations): A two-step equation is solved by undoing addition or subtraction first and multiplication or division second — the reverse of the order you would use to evaluate it.
- [Percentage Word Problems Solver](https://photomathsolver.app/en/pre-algebra/percentage-word-problems): A percentage word problem is solved by working out which of the three quantities is missing — the part, the whole, or the percent — and then applying $\text{part} = \text{percent} \times \text{whole}$.
- [Linear Equation Calculator — Free, With Steps](https://photomathsolver.app/en/algebra/linear-equations): A linear equation is solved by collecting every variable term on one side and every constant on the other, then dividing by the coefficient that remains.
- [Quadratic Equation Solver — Roots, Steps, Free](https://photomathsolver.app/en/algebra/quadratic-equations): A quadratic equation is solved by factoring when it factors cleanly, and by the quadratic formula $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ when it does not.
- [System of Equations Solver — Free, With Steps](https://photomathsolver.app/en/algebra/systems-of-equations): A system of linear equations is solved by substitution when one variable is already isolated, and by elimination when adding or subtracting the equations cancels a variable outright.
- [Pythagorean Theorem Calculator — Free, With Steps](https://photomathsolver.app/en/geometry/pythagorean-theorem): The Pythagorean theorem finds the third side of a right triangle from the other two: $a^2 + b^2 = c^2$, where $c$ is always the hypotenuse.
- [Area and Perimeter Calculator — Free, With Steps](https://photomathsolver.app/en/geometry/area-and-perimeter): Area measures the surface a shape covers and perimeter measures the distance around its edge — each shape has its own formula for both, and they are never interchangeable.
- [Surface Area and Volume Calculator — Free, With Steps](https://photomathsolver.app/en/geometry/surface-area-and-volume): Surface area totals the outside faces of a solid while volume measures the space enclosed inside it, and each standard solid has its own formula for each.
- [Similar Triangles Calculator — Free, With Steps](https://photomathsolver.app/en/geometry/similar-triangles): Two triangles are similar when their corresponding angles are equal, and their corresponding sides are then in one constant ratio throughout.
- [Right Triangle Trigonometry Calculator — SOHCAHTOA](https://photomathsolver.app/en/trigonometry/right-triangle-trigonometry): Right-triangle trigonometry finds an unknown side or angle using SOH-CAH-TOA — sine, cosine and tangent as ratios between two sides of a right triangle.
- [Trig Identities Solver](https://photomathsolver.app/en/trigonometry/trig-identities): A trigonometric identity is an equation true for every angle, used to rewrite an expression as a simpler equivalent one rather than to find a value.
- [Law of Sines and Cosines Solver — Triangle Calculator, Free](https://photomathsolver.app/en/trigonometry/law-of-sines-and-cosines): The law of sines and the law of cosines solve triangles with no right angle — the law of sines pairs each side with its opposite angle, and the law of cosines generalises the Pythagorean theorem.
- [Trigonometric Equation Solver — Free, With Steps](https://photomathsolver.app/en/trigonometry/trigonometric-equations): A trigonometric equation is solved by isolating the trig function, applying the inverse to get one angle, and then adding every other angle in the required interval.
- [Limits Solver](https://photomathsolver.app/en/calculus/limits): A limit is evaluated by direct substitution whenever that produces a number; getting $\frac{0}{0}$ means the expression needs algebraic work before the limit can be read off.
- [Derivative Calculator — Free, With Steps](https://photomathsolver.app/en/calculus/derivatives): A derivative is found by applying whichever rule matches the structure of the expression: power, product, quotient, or chain.
- [Integrals Solver](https://photomathsolver.app/en/calculus/integrals): An integral is found by reversing differentiation — recognising which function would differentiate to give the integrand, then adjusting for constants.
