I completed the challenge: 5 I feel good about my code: 5

I'm really proud of how this turned out, and in less than a few hours despite a lot of initial discouraging headaches that I might not be ready for this. I believe it works exactly as you would expect a calculator to work. The console also has some live behind the scenes feedback of what is happening.

I think the code is not at all dry and has a lot of artifacts from failed attempts. Granted I haven't tried much to clean it, but regardless would love any thoughts on ways to make it cleaner without compromising readability.

Added additional commits since creating this pull request, which mostly act as making code more dry, cleaning up old artifacts, and following OOP pillars.
