Code Challenge: Method Returns: Part 2

Hi,

What is the challenge asking when it says to make sure the string is formatted nicely?

I have a code that works perfectly but it still says Bummer.

Thank you!

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

a = 15
b = 4
mod(a, b)

Once a function returns a value it stops executing. In other words everything after the return line is completely ignored and never ran. On top of that this challenge want the function to return the string, not the value of a % b.

It's also worth noting that if you had placed the puts line above the return line then you would end up with an infinite recursive loop since your function calls itself which results in it calling itself again and then again and so on.

If you actually return the string and just use the a % b equation directly for the c placeholder like this:

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

Then your code will work.
