I can't see to get this right https://teamtreehouse.com/library/ruby-basics/ruby-methods/method-returns-part-1

I've tried repeatedly to get through this code challenge and this one has me stuck. I really need some guidance, please.

method.rb 
def mod(a, b)

end

You've got the first part correct. After that, the task is just to ask the method to return the remainder of "a" when divided by "b." Simply write the method's return value as a%b.

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

you just put a return statement in the body of the function, returning what it asks for. the modulo or mod operator % returns the remainder of division, so if 8 divided by 5 is 1 with a remainder of 3, then 8 % 5 = 3.
