PhotoMath Is A Free App That Can Solve Equations Through Smartphone Cameras

Math is one of the hardest subjects in school, which is why owning a graphing calculator seems like a necessity for students. But what if you could use your smartphone to solve equations by pointing the camera at the problem in your textbook instead of using a graphing calculator? That is the idea behind PhotoMath. PhotoMath is a free mobile app that can read and solve mathematical expressions using your smartphone camera in real time. PhotoMath may sound like it is simply helping kids cheat, but the app also provides a step-by-step guide showing how each of the problems are solved. The step-by-step guide is beneficial to students that do not have access to a tutor and struggle with solving math problems. Parents can also use the PhotoMath app to jog their memory when teaching math to their kids. “PhotoMath currently supports basic arithmetics, fractions, decimal numbers, linear equations and several functions like logarithms. New math is constantly added in new app releases,” says the description of the PhotoMath app on iTunes. The PhotoMath app uses optical character recognition (OCR) technology to read the equation and calculates the answers within seconds. There is a red frame in the PhotoMath app that you have to use to capture the equation.
