The app is excellent,it perform all calculations, I rate it 5 stars continue improving, if you're stuck on a question the app shows you all the different ways to solve it step-by step.

Used it in trig and calc with great results, even though sometimes I don't get the answers, i got to learn more from this app and it even has explanation which is very helpful for me! 5/5 stars. It's fantastic, but you have to wait to ad new solutions to different teniques of math which is understandable.
