This might be due to the two 'a''s you have in your string. Also the .to_s-method is outside of the curly braces, which means it will just be printed, rather than executed on your ruby-code. Also I believe you do not need .to_s because the code itself is already printed as a string.

Perhaps something like this?

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

Hi Bryan,

Rogier provided good solution code. The main problem in your code is that #{mod} is the only thing being interpolated. The .to_s will literally be printed as text at the end of your puts statement just like the rest of the text before #{mod}.

Cheers,

Mike
