Photomath application uses your phone camera to calculate both simple and complex math problems. The app uses your phones camera to solve the problems. We can solve linear and quadratic equations. The idea is simple just focus your phones camera on printed or written math problems and the app calculates the problems and gives you the answer in a giffy.
The best thing about the app is that it shows the step-by- step calculation rather than giving just the answer. A good app to do math problems. I being a math student recomments this app to every student out there.
