How do I interpolate a return value in a method?

"In the previous challenge, we wrote a method that returned the remainder of two arguments when divided. That's cool, but it would be nicer if the method returned the remainder in a nice full sentence. Use string interpolation to return the remainder inside the sentence “The remainder of a divided by b is c.” where a is your “a” variable, b is your “b” variable, and c is the value of a % b."

So I understand interpolating a string using #{ }. But I don't understand how to get the remainder value set to "c" Here's the coded that I have so far:

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

mod (10), (7)

c = a % b

Should C be one of the variables in the method? Or am I on the right track with setting "C = a%b"?

I feel like C has to be in the method as a third variable. Here's what I've updated the code to look like:

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


mod (10), (7), (c)

I got stuck at the same exact place a few days ago and even today, when I resumed. I have put this question to the Support.

Hi there! I suspect that you are overthinking this. Again, the challenge never asks for anything to be printed... only returned. So puts will never be used at all. Also, the string you're returning requires a period/full stop at the end. Not including this will cause the challenge to fail. Do not call the method yourself. Treehouse is going to call the method. Calling the method yourself interferes with what Treehouse is sending.

Here's a solution in one line of code:

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

Here's another solution using a third variable:

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

Hope this helps! :sparkles:

Thanks again for your help! This makes much more sense.
