Update this app to have a nice landing home page. Remove the suggested home equations. It should not keep last answers on the home page, rather on a hidden window on an icon coman. As the equation problem grows it should not be hidden but displayed in full. The solution or answer should not be on a separate window/page from the problem, it helps to check wrong input instantly.
