Your problem has nothing to do with class variables.  The gets() method 
returns a *string* not a number.  When the user enters some characters 
and then hits return, gets() will return something like this:

10\n

The '\n' is the newline character that was entered when the return key 
was pressed.  The second string will look something like:

20\n

When you add those strings together, you get:

"10\n20\n"


Then when you use puts to output the string, your computer screen 
converts the '\n' characters to newlines, which produces:

10
20
