Been alot of help for my son who is taking Geometry, cheating? I don't use it for cheating, or for "checking" my homework, dISAPPOINTING, dont let your maths teachers see this or they will get a heart attack and NO MORE DIFFICULTY IN HOMEWORK. I liked this application very much, a useful, wonderful and easy application, but there is one negative and I think that it is not considered negative as well, which is the lack of diversity of languages, I hope there is the Arabic language to simplify things and thank you.

10/10 app I would definitely recommend it to others who struggle with math, 5 years to go of study for me. As a 7th grader I do believe this is the best problem solving app, best math app out there.

App is a best app for students because it has the whole book solution with explaination but some problem are not having the correct solution and not having the proper step so please try to work on this issue.
