Absolutely amazing app. It even shows how to solve the problem in different ways for free so you can also learn how to solve it yourself. Also, when your answer isn't the same as the app it still exsplains how to get the right answer, to me it couldn't get any easier.
This is simply brilliant. Convenient to use as we can capture the pic of the question or manually type it to get the solution, the ONLY App that works without paying anything. This app explains problems to me supplementing what the instructor teaches, it's really good app it's can help u to understand the problem and give u some solving step.
