( CNN ) -- Say it with us : Kids today have it sooooo easy . A new smartphone app will do their math homework for them , provided it 's not too complicated . PhotoMath by microblink uses a phone 's camera to solve equations and then teaches you the step-by-step method for solving it yourself . The app can do arithmetic : addition , subtraction , division and multiplication . It can handle fractions . It knows what 23 is and can calculate the root of 246 . It can even do simple linear equations , provided the x you 're solving for is italicized so the app does n't confuse it with the x multiplication symbol . The only catch is that the equation you 're trying to solve must be printed text , rather than handwritten . So forget trying to calculate that tip by scribbling it on a restaurant napkin . ( Do n't worry , there 's already a million apps for that . ) The app may pose a problem for schools are already dealing with smartphone overload . Math teachers will have to be extra vigilant during tests to prevent students from cheating . The PhotoMath app is available for iPhones and Windows phones and is coming to Android phones in 2015 .
