Recognition and automatic solution of equations

Free PhotoMath application is useful to many students. When you hover the camera on the equation, the program recognizes mathematical symbols in the formula (OCR works), performs calculations - and gives the correct answer.

The idea is so simple that there is even nothing to explain. There are only two questions: why no one did it before and why it was not when I was in school.

Immediately you need to realize that the program was not created for cheating. In each normal textbook, the correct answers to the problems are indicated. After all, the main thing is not the answers, but in the process of their search. Knowledge is checked not by the final result of calculations, but by the algorithm for solving the problem. For example, if an error / typo occurred somewhere and the answer does not agree with the problem book, but at the same time the student demonstrated the correct logic of the decision, then he still deserves the maximum rating. Even if the answer is wrong.
