Confusion with question-How to I show the variable 'c' in the string?

I am completely confused by how I am supposed to incorporate the value 'c' (a % b) into this string. I have re-watched the lesson to see what I missed and think I'm just not grasping the concept behind it. If anyone can explain to me what the question is asking and how to resolve this I'd appreciate it! Thanks.

Here is the code I have entered: 

def mod(a, b)
  puts "The remainder of #{a} divided by #{b} is #{a % b}."
  return a % b
end

I just tweaked your code to add syntax highlighting. :)

Hi Doug,

You are pretty close. First, you want you method to return a string, not print to standard output. Second, when interpolating a string, you have to use variables inside your variable placeholders. You would want to declare a variable c = a % b. e.g.

def mod(a, b)
  c = a % b
  return "The remainder of #{a} divided by #{b} is #{c}."
end
