Mathway

The power of the smartphones can be used in some ways, and we can do some pretty interesting things, such as scanning a written document and transcribing it to a text file. The same power can be used for more complex problems that we find in other domains, such as math.
With Mathway users just have to point the camera at the equations, take a picture, and get an instant result. Before you start taking pictures of unsolvable problems in mathematics, you need to know that the app is limited to some fields, such as basic math, algebra, trigonometry, calculus, statistics, finite math, chemistry, graphing, and a few others.
Of course, if you scan handwriting you better have good and intelligible handwriting. Otherwise, it won’t work.
