Ive had this app for a long time...

...But you keep on making it better and better! One of the first apps I ever downloaded and the best one I have, at that. Thank you so much for such a wonderful application. Its easy and looks beautiful. A must-have for anyone who appreciates mathematics.
For all those who complain about how your simple calculations dont work: try using operators and learn orders of operations or gtfo.
