Every now and then, an app comes along that combines two existing technologies in a way that just makes sense.

PhotoMath does just that, utilizing your smartphone's camera to quickly solve math problems.

PhotoMath only works with printed text, so unfortunately it won't be solving your scribbles anytime soon; you'll need a printed sheet of paper or a textbook.

You then position the math problem you want solved within the red frame and PhotoMath does the rest, crunching the numbers and popping out an answer.

While it seems likely that most will use PhotoMath to sidestep actual learning, PhotoMath includes a "Steps" button that cleverly walks you through the steps from the original equation to the final answer.

For now, PhotoMath only handles math problems that include fractions, decimal numbers, linear equations, and several functions like logarithms. The PhotoMath team says they'll be including support for more-advanced math equations in the future, but for now, it won't get you through your calculus homework.

You can download PhotoMath for free for both iOS and Windows Phone, and an Android version is in the works and scheduled for an early 2015 launch.
