Math was not my forte so I had to break out the college algebra book from years ago. I selected several control samples, then ran the program using those samples that where gathered. I have not had any issues, problems or wrong answers. A couple of the larger in-depth questions took a little bit longer but I still had a solution, it was step by step. I've never tried any other math apps before to have a comparison but this one is a good one to have on your phone specially if you're a student.

An awesome app. It helped me out for my exams a lot. You can ask whatever question you like to the tutors. Other apps and sites take huge amount of money for doing literally the same thing. Its free here. I would recommend this app to all the students starting from class 10 to Post Graduation. Very useful. I would've given a 5 star but the only little problem is that most of the time, tutors give a direct answer without doing much of steps for the problem sums. I think thats something to improve
