Great for Answers. Not for Learning.
To keep this brief, this is very useful tool, but makes it hard for one to learn from the mathematical problems as it only offers you the answers. If you want to learn step by step you have to pay a $20 monthly subscription which clearly disappointed me. I would be more than glad to pay a $20 annual subscription, but that obviously not the case.
