Only bad thing is you have to pay for an upgrade to see how the problem was solved, also listening to calming music so thats why i sound like that. The app has all the symbols you need.
Really helps not only dose it give you the answers it also shows you and explains the answer thoroughly. And I don't understand my teacher's lessons. I'd say it's a good app especially due to the calculator and the scanner. It include all the functions a student would need in high school math and some college math too.
