Ratings and reviews

The app cannot even solve an algebraic equation... 90% of the time it says "Problem solver failed for the imput problem!" Come on guy, I paid for this to work. Back in 2017 when I downloaded the app for the first time it used to work like a charm. But after a while, when I bought it, several updates made it worse every time. Get to work and fix this.

I love this app very well because it solve and explain difficult for me. But sometimes it will tell me that it needs premium pack to continue which I don't understand. But it is the best I have ever seen that solve calculus and explain it very well. Please I want to learn how to purchase this application my fellow users. If you see this message reply to me. Please.

How do I find the key for the mathematical constant 'e'? I looked for it in the menu "+keys" but it's nowhere to be found! I tried the alphabetical 'e' key but it doesn't seem to work! Please respond.
