Amazing I have got completely correct math homework that only takes me 10 seconds to do which is convenient as I ride my pony after school and so don't have much time as the annoying spanish teacher keeps replacing all our preps with spanish.
This app is great, it really solves your problems in mathematics, shows the steps, and doesn't have many adds. But atleast without paying it's worth it. The only problems math app couldn't help me solve were real advanced and if you know a roundabout way you can still solve em.
I highly recommend this app, it explains everything, even if you didn't pay the premium version, it really helps you to understand maths. I am a user of this app and yes it help a lot though the hassle of this is needs a load all the time, best for Helping and solving A Difficult problem and this is the Best so far.
