We're continuously working on improving calculation steps so that users can understand them easily. An entire team of highly gifted mathematicians is working on putting math steps into the app, but mistakes may happen sometimes.
If you have found an error, please use the feedback form at the end of the solution: "Was this solution helpful?" - answer NO, "Sorry to hear that. Care to explain?" - answer YES, tap ADD IMAGE & attach the screenshot of the math problem with the wrong or incomplete steps.
If you have learned a different method for solving that math problem, let us know your suggestion by sending an email to firstname.lastname@example.org.
Thank you for feedback!
Ooops! Try again...
Sorry to hear that, how can we improve?
