I have used this software for my thesis project in mechanical engineering to solve some equations. It is very user friendly and easy to use. The only thing which i found confusing was how you can save the output file as an excel sheet but not pdf or word. So it would be great if they make these options available so we don't need to export our files manually every time we want to update them. Overall its good product with lot of features. My work has been made easier by solving complex equation using this tool.
