Version 3.1.1

Fixed two small layout issues which bubbled up in iOS 11.2:
- line above keyboard kept shrinking in certain scenario
- some subscripts in Detailed solution of quadratic equation were missing

Only turned out one mistake!


Seriously saved me when I was super late for class, simple and easy to use. Even lets tells you how to solve on your own~ only mistake was the it flipped the positive and negative of a specific factor so its always good to check your answers!

Need to be able to use large decimals/scientific notation


I like the set up and it is very simple, however you cannot put large decimals. I won't be able to use this app since a lot of the problems I need to solve are large decimals/scientific notations.



The app idea is awesome for students learning this stuff, that is why I rated it 2 stars instead of 1. But the issue is it will not open, it keeps crashing when I try to open it
