Comprehension Questions

Question	Answer
Describe how you stored user input in your program?	I stored user input into three different variables (num_1, num_2, and operator) using gets.chomp. I used a simple regex to test that user input included and integer, and I tested num_2 to make sure it was greater than zero (for the case of division by 0)
How did you determine what operation to perform?	First I defined four different methods to compute addition, subtraction, multiplication, and division. Then I wrote a case statement that evaluated the user input for operator and then ran the appropriate method based on that operator. Within the case statement I converted the values stored in my num variables to floats, in case the answer contained a remainder.
Do you feel like you used consistent indentation throughout your code?	Yes...? thanks to the new command+i shortcut.
If you had more time, what would you have added to or changed about the program?	I plan to revisit this program later and tackle the optional enhancements!

Great job! The calculator has all the expected functionality

We did not have a requirement that the second number must be greater than 0 ;) Only in the case of dividing by 0 should you handle it.

Your check for if num_2 is greater than 0 only happens once because you put it in an if instead of until. (For example, you could just type "-2" two times)

I actually don't know what Ruby's loop do does, but from what I've learned about it, I wouldn't recommend using it!

Looks good otherwise!
