The app uses image recognition technology to identify the numbers and symbols that make up the problem: division, multiplication, parentheses, and so on. Just open PhotoMath, point the camera at the problem, and the answer appears instantly. You also have the option to view a step-by-step solution.
The app works well, both in character recognition and in solving problems, but it has some limitations, such as recognizing handwritten numbers. MicroBlink promotes the app as a learning aid. In fact, the step-by-step problem-solving process is a great help when questions arise along the way.
