A Simple Questions and Answer application, just need help.

Okay. I want to make an app where you input some text and its giving you a simple text back. Kind of like a console where you input for example : “Whats 10+14” and the console answers with “24”. But still I want to do this in a good looking way. Any ideas on where to start? Or is there any good tutorials? (I’ve watched one “official” tutorial made by Unity on youtube but since its too old I can’t quite follow it because some stuff has changed. I want an app looking kind of like Hacknet. (You insert commands and get answers back)
Im happy for anything. I just want to start somewhere and don’t know how to.

Start with the unity user interface tutorials. But remember that the UI only has a basic look and feel.
So the way all this looks is up to you.
