This project is from The Odin Project. This project was completed before TOP clarified the instructions to only evaluate a single pair of numbers at a time. If you are doing TOP, do not attempt to re-create this functionality!

I had to re-factor my work several times as I realized how different functions and variables interacted with each other. I hope to learn more on how to plan and execute a project like this more efficiently. As I am learning, I just took everything one step at time and then re-factor when necessary.

I really enjoyed working with regular expressions and probably over-used them to format the display numbers.

The calculator is not 100% scientifically accurate. Although, I did use the order of operations published by Wolfram:

1. Parenthesis
2. Factorial
3. Exponentiation
4. Multiplication and division
5. Addition and subtraction
