I'm not sure what else this challenge requires. How do I make sure the string is nicely formatted?

I'm not sure if I need to create the variable c here or not. It works fine when I do this in the console, so I have no idea what's wrong with this code. This is the challenge question "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."

The error I keep getting is "Make sure you return a nicely formatted string."

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

puts mod(2, 6)

Well I haven't used any Ruby yet, but from what I can tell by reading your code, you aren't returning a string, you are returning a number. I don't know what puts does but I am assuming that it is some sort of printing to console/screen/browser, and right now that is not what the challenge is calling for, it is calling for you to return the string that you formatted above, but also include the answer in it. At least that is what I think, having not used Ruby before I just copied your method from earlier and used the same concept:

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

Congrats :+1:

You understood what puts meant! It prints stuff to the screen. It's short for "put string"'

Ah, that's easy to remember put string. Thanks, maybe after my school semester dies down (so many programming and software engineering projects) I may take my time to learn some Ruby.
