This code will pass that challenge - I just looked it up for you:

def mod(a, b)
  return a % b
end

You need to return the result of the modulus operation from the method.

Do you mean the % operator?

Actually Ruby automatically returns the result of the last expression evaluated, so why should we manually return the value?

Yeah - good point. I've been in Java all week so forgot that. Some would say adding the explicit return keyword adds clarity; others would say it doesn't. The code challenge accepts either version.
