Missing : end of the line

[programmin1]

def is missing : at end of the line.

Funny, it kept giving me syntax errors, but I got this to work:

  def self.add(a, b)#:
    a + a
  end

  def self.subtract(a, b)#:
    b - a
  end

Hey @programmin1. Thanks for looking into making this project better!

Actually, the :s would be for python. In ruby we don't need anything at the end of the method definition.

Most likely, the reason that it worked with the # is because that's the ruby version of a comment -- so it would have ignored the : afterwards.

Let us know if you find anything else we need to address.
