App is great! I've always struggled with math. But most of the time it works so I'll give you 5 stars, easy to use great for all your needs, i used it to walk me through the steps and after I figured it out I did all of my homework and used it to check if I got the correct answers.
6/5 stars, a huge help with College math homework, well worth the cost, after all it has helped a lot so I gave it 5 stars. An extremely powerful tool if used effectively.
