Algebra can be a bane to students and while some turn to their teachers for help, others request for assistance from parents, siblings and tutors. With PhotoMath, they now have another source of help. Best of all, it’s free!

PhotoMath, which is now available on iOS and Windows smartphones, leverage the devices’ cameras to scan a printed math problem and provide an answer in an instant — complete with the steps to solving the problem.

All the student needs to do is to install the app, scan the equation within a red frame and the app does the rest.
