学渣福音：数学APP拍照就出答案

 　　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, subtraction¹, division and multiplication². It can handle fractions. It knows what 2? 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 doesn'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 scribbling³ it on a restaurant napkin. (Don't worry, there's already a million apps for that.)

　　The app may pose a problem for schools are already dealing⁴ with smartphone overload⁵. Math teachers will have to be extra vigilant⁶ 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.

　　跟着我们一起说：今天的孩子们过得太舒服了。

　　据CNN10月22日报道，Microblink公司推出了一款新型智能手机应用PhotoMath， 能轻松帮助学生解决数学题——只要不是太复杂。只需要将手机的摄像头对准要计算的方程式，PhotoMath便会给出清晰的解题步骤。

　　PhotoMath目前可以解决基本运算加减乘除，还能处理分数。例如，它可以计算出246的根以及2?的值。它甚至还能解决简单的线性方程。不过，在使用时，用户需保证x是斜体的，否则PhotoMath不能区分出x和乘号。

　　不过，PhotoMath目前只能识别打印字体的方程，手写的还无法识别。因此，不要去尝试用PhotoMath去解决写在餐巾纸上的问题。（别担心，其它很多应用都能识别手写体。）

　　这款应用可能会造成问题，因为学校已经在处理智能手机的很多问题。为了防止学生在考试时用PhotoMath作弊，数学老师在监考时需十分警惕。

　　目前，这款应用支持iPhone和Windows phone用户，而Android用户则要等到2015年。
