And without app I'd be struggling really badly. When taking pictures i have no problems, my friend has problems because he has a low pixels camera, the more your pixels the better the photo.
This app helps me meet deadlines for math when my schedule is busy. It'll be hard to resist to use for every problem. I found the app really useful for a student It helps me especially to understand algebra it not only shows the answer but how to do the process it's perfect for a student or even an adult :) (In addition there are not too many ads, I've never had any anyway!).
