Doubtnut leverages technology to make education accessible for all. We have created an App using which students can ask study questions in Math by clicking the picture of the problem or concept. Subject matter experts then create a Khan Academy style video to answer each doubt. Why video, because in our experience as teacher/educator we have seen students not being able to understand text solutions. In fact around 30% of the questions asked on doubtnut so far are actually solved examples from textbooks.
