Ruby basics - Method Arguments

I am using the exact same code as Jason:

def add(a)
  puts a + 2


But its outputing the error code he showed.

irb(main):006:0> ruby methods.rb                                             
NoMethodError: undefined method `rb' for #<Array:0x007f7994a30650>           
        from (irb):6                                                         
        from /usr/local/bin/irb:11:in `<main>' 

I am confused.

You're running the script from within irb. You just need to run ruby methods.rb from the command line instead.
