- Attempting to create a simple four or five function calculator in Ruby. Originally did something like this in college written in C. That's where the idea came from.
- Initially checked in the code. Needs a lot of rework.
- Can I, or should I, separate this into classes and modules?
- DRY, there's a lot of repeated code, e.g.
gets.chomp.to_iSee about defining it in a module and then call it
-
Refactor so the output repeats the expression and displays the answer
-
Refactor to work with more than two numbers
- Etc.
