CalculatorWhat We're Looking For
Fantastic work on this Monick! Your code is so clean, logical, and readable, and a lot of the things you did were particularly clever and/or elegant. I'm really happy how you practiced making methods and using the If you had more time on this, I would LOVE to see you pull the logic of getting user input and checking its validity into a method. The code that you wrote for getting both numeric input is the same! I've added a few other comments, some of them about the Overall, this project was GREAT! Great work! |

Nice! This method you defined is sooo useful and so elegant! In general, I may suggest an explicit return with return true if Float(string) rescue false, even though it ruins how elegant it looks. SORRYYY

this is so fancy and it makes me happy. Maybe consider renaming key and value to operation and symbol?

| user_operator = gets.chomp | ||
| #call on check_operator method to check if user entered a valid operation | ||
| if variations_list.include?(user_operator) == false |

Another way to write this is if !variations_list.include?(user_operator), because the ! negates it

Totally a small thing, but you named this variable results, when it never will be an array, it will always be one result. Consider renaming this to result
