A complete online math solver: free, fast, and step-by-step
Microsoft Math Solver became a popular choice for students because it offered a quick way to solve math problems by photo, drawing, or typing , and showed every step of the solution rather than just the final answer. If you have been looking for that same experience but want a tool that runs directly in your browser without downloading an Android or iOS app, Free PhotoMath AI is built to be your go-to alternative.
What can an online math solver do for you?
A good math solver removes the friction between you and a clear, well-explained solution. Whether you are stuck on a tricky algebra equation, need to evaluate a definite integral for calculus, want to verify a trigonometric identity, or are working through a multi-step word problem, an online math solver gives you the answer plus the reasoning. With Free PhotoMath AI you can type the problem into the calculator below, paste an image of your homework, or upload a PDF , and within seconds receive a step-by-step breakdown that matches what your textbook or instructor would show.
Why students choose a web-based math solver over an app
Mobile apps like Microsoft Math Solver are convenient on the go, but they have limitations: you need to download and install them, they consume phone storage, they sometimes require account login, and they only work on your phone. A web-based math solver works on any device with a browser , your laptop in the library, a tablet at home, a school computer, even a friend's phone you borrowed for a minute. There is nothing to install, nothing to update, and your work is never tied to a single device.
Step-by-step solutions for every type of math
Step-by-step explanations are what separate a real learning tool from a basic answer key. When you use the calculator above or the photo solver on our home page, you will not only get the result , you will see how the expression is parsed, which order of operations applies, where each substitution or transformation happens, and the final answer. This kind of guided walkthrough is exactly what makes Microsoft Math Solver popular among middle and high school students, and our solver delivers the same approach across algebra, geometry, trigonometry, calculus, and probability.
Algebra, calculus, trigonometry, and beyond
Our solver handles the full curriculum: linear and quadratic equations, systems of equations, polynomial factoring, rational expressions, exponential and logarithmic functions, derivatives and integrals (definite and indefinite), limits and series, sine and cosine identities, geometry proofs, matrices and vectors, probability and statistics, and word problems. If a problem can be expressed clearly, our AI can read it, parse it, and walk you through the solution , exactly the breadth you would expect from a Microsoft Math Solver alternative.
Photo input: solve math just by taking a picture
For more complex problems , especially handwritten ones, multi-line equations, or full textbook pages , the fastest workflow is photo input. Snap a picture with your phone or upload an image from your computer, and the AI reads the math, identifies the operations, and produces a clean step-by-step solution. This works whether the problem is printed or handwritten, in pencil or pen, on lined paper or a whiteboard. The same photo-to-solution capability that made Microsoft Math Solver useful is built into our solver and available without installing an app.
Better than a basic calculator
The calculator above is a fully functional scientific calculator with trig functions, logarithms, exponents, square roots, factorials, π, e, and a clean keypad you can use with your mouse or by typing directly. But unlike a typical scientific calculator, it generates step-by-step explanations of how it reached the answer , so you actually learn the method, not just the result. Combined with the photo solver on our home page, it gives you everything Microsoft Math Solver does and more, in a single web interface.
