It can help you learn math like a privet teacher, it can take questions or take pictures and solve the problem, it makes math a lot easier, the scaning works well too, this app is just too perfect! The app itself gives language optional (such as Malay, Indo etc.

Phenomenal app, not only can I cheat on my math tests but I can also write the questions down on a ripped off piece of paper, put in my pocket, ask to go to the bathroom and scan it. Incredible data at your finger tips in the matter of seconds.
