Very good, good, good calculator app.. I am very happy that I can learn how to use CW calculator by using it. But some features are not working or some features are not added.

Good calculator, supposedly a close resemblance on Casio Classwiz, but with bugs. Found this bug just after trying for a short while: 1. Can never make the default Ans in surd form, despite changing in setting 2. √(72*75/288) gives Maths Error
