Mrs.

Waste of money, no good examples or tutorials, very poor. I want my money back.

not interactive

Examples are poor. No interaction. If you are going to read something, read your textbook. Save your money.

This is not a program

As a guide this app is OK but it does NOT solve anything for you. You find an equation from its list then use the steps provided to solve it yourself. If this app allowed you to input any of the equation types provided in the guide and then solved it for you, step by step, just like in the guide, I would rate this a 5.
