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.

MUST GET THIS APP! This is unlike any other app out there that actually allows you to scan word problems and number problems at the same time with ease and it's free in that regard in the little attempts of me scanning questions. This app genuinely cares for its users and tries to make the best experience possible, which is why it deserves all the praise it can get! Sure there is a membership if you want, but there are coupons for free that are reasonable for the content provided. Bixby Thanks.

It was great until they removed the mission and free coupon option. I understand it's probably unfair because it's way too cheap to reward the teachers for it but not all students can afford to see a proper example and solutions for their specified math problems, not all students are able to afford proper education from bad teachers who didn't had the patience to teach them properly. Or my app just glitched I'm confused
