Adding Midterm 

On line 17 you can do `a3 = gets.strip.to_i` which will allow you to remove lines 18-31. The way it's currently written `a3` will always be set to 30 since the user input will always be interpreted as a String and not a Fixnum. If the user inputs a word `.to_i` will convert it to `0` so you could use this value in a conditional as well
