The free version is good enough but the paid version goes more in depth on how each step is solved. Learning maths is now easy with this app because they even solve the questions and i really understand it.
I had no idea there was any app like this out here. Words cant explain my thankfulness. Very hepfull with my algebra homework, very easy to use and 100% accurate I would definately give it a 10 out of 10, never seen such a useful math app.
