How come Photomath is not recognizing problems from my textbook?

One day we hope to explain every type of problem that exists in the world, but today Photomath Plus is limited to problems in supported textbooks.
Our math experts are working hard to write helpful answers to problems for the most commonly used textbooks, but there are still a whole lot of textbooks out there to cover.

If the app doesn't recognize your textbook, it means that we haven’t solved it just yet ― but you can vote for it (you’ll see the prompt when searching for it in the Textbook Solutions library by name or ISBN), and we'll do our best to solve it as soon as possible! You can find the list of books currently covered by clicking the textbook icon at the top right of the scan screen.
