If you already have the image saved, you can easily upload a screenshot directly from your photo gallery. xMath instantly scans the image, reads the math problem, and displays the correct solution on your screen in seconds.

The app breaks down every calculation into clear, step-by-step instructions. You can follow the logic from the very first step to the final conclusion. This feature allows you to learn the underlying concepts. The next time you face a similar question on a test, you will know exactly how to solve it on your own.
